In 2017, the latest development on Ni-based catalysts for both oxygen reduction/evolution reaction (ORR/OER) and as well as hydrogen evolution reaction (HER) have been carefully established and published by Vij, V. et al . Indeed, several kinds of nickel-based and nickel-incorporated materials have been issued as an interesting materials to outperform the state-of-art materials for (ORR/OER/HER). These nickel-based or incorporated include nickel alloyed with transition metals (TMs), non-metallic dopants, and as well as Ni-MOF-based materials. These kinds of materials made of nickel demonstrated outstanding properties toward the targeted reactions with high efficiency. It is mentioned that although these nickel-based materials present high catalytic efficiencies and thermal stabilities, there exist always low electrochemical stability under extremely concentrated acid/alkaline conditions, which is a major setback in offering their commercial viabilities. So, due to these shortcomings researchers always are seeking further improvement of the entire performances of nickel-based catalysts in order to lower overpotentials, and increase both the current density and electrochemical stability. A nickel-based bicarbonate Ni0.9Fe0.1(HCO3)2 has been engineered for catalytic purposes especially to be used in the alkaline oxygen reduction and evolution reactions as highlighted in Gui, L et al's paper . Indeed, it was found that inducing 10% of the iron defect into nickel-based bicarbonates catalyst can significantly boost the real valence of nickel ions, and hence mold the electrocatalytic aptitude of bicarbonates. Among the designed Nibased bicarbonates, Ni0.9Fe0.1(HCO3)2 shows high catalytic activity for both oxygen evolution and reduction reaction with a potential difference of 0.86 V, beating most of the reported precious-metal-free catalysts. So, this article demonstrates that bicarbonates and carbonates can deserve powerful potential as precious metal-free catalysts for both OER and ORR. Also, Cheng,Y et al reported the synthesis of atomically dispersed bimetallic FeNi catalysts embedded over N-doped carbon nanotube with catalyst packing of 2-7 wt% with different Ni: Fe ratios as highly and stable reversible OER and ORR catalyst for metal-air batteries. The dispersed bimetallic FeNi demonstrated superior catalytic activity than the single dispersed (Fe or Ni) for both OER and ORR catalysis. When compared to Ni0.9Fe0.1(HCO3)2, FeNi@N-CNT exhibit a lower potential gap of almost 0.81 V between oxygen evolution and oxygen reduction reactions. It is suggested that this FeNi@N-CNT exhibit better stability compared to the state-of-the-art Pt/C and Pt/C+Ir/C catalysts for the reversible OER and ORR. So, the enhanced catalytic performances might be attributed to the contribution of the synergistic effect coming from both Ni and Fe, as well as the conductive support (N-CNT). Therefore, this study might be inspiring as a new platform for developing highly active bimetallic catalysts for catalytic purposes. A computational method has been adopted to elucidate the mechanism of the carbon dioxide reduction to formic acid over a Ni-based catalyst as described in Zhao, Z et al's work . In this study, it is demonstrated the origin of the metal surface poisoning by CO and it also provides a strategy to eliminate this poisoning species through the HCOO* activation pathway and deactivation of the COOH* competing pathway. So, different Ni-based nearsurface-alloys (NSAs) have been identified to possess both high selectivity and reactivity of efficient formic acid production from CO2. These catalysts include Ni/Ti, Cu*/Ni, and as well as strained Cu/Ni NSAs. Moreover, Wang, C et al demonstrated that the catalyst properties such as surface acidity/basicity, oxygen species, redox properties, and so on are the key parameters, which are needed to be focused on in order to improve the engineering of nickel-based catalysts, which subsequently can yield high conversions of greenhouse gases (CO2/CH4) into syngas generation while decreasing catalyst poisoning through carbon deposition. It is carefully highlighted the lasted innovations before 2015 in terms of Ni-based catalysts for further development of a catalyst for (CO/H2) production from greenhouse gases, which has more advantages than (CO/H2) synthesized from the steam reforming of methane (SRM), as it can be directly realistic to flue gases and doesn't require the CO2 separation from the flue gases. The syngas (CO/H2) generated from the dry CO2 reforming of methane (DRM) over these nickel-based catalysts is valuable for successive usage in the Fischer-Tropsch process for the synthesis of heavy hydrocarbons. Also, in 2017, Bian, Z et al carefully reviewed and published the latest advances on Nickel-based bimetallic catalysts for the dry CO2 reforming of methane (DRM) reaction. Their review focused especially on metallic Ni alloyed with both noble metals (Pt, Ir, Ru, etc.) and transition metals (Co, Fe, Cu) for further improvement of the catalytic performances of bimetallic Ni-based catalysts for syngas production from (DRM) reaction with a distinctive accent on the fundamental principles which lead to synergistic effects. Also, some outlooks are reported for future engineering of Ni-based bimetallic catalysts. So, it is noticed that inducing a second metal on Ni-based catalysts boosts the Ni catalyst's performance with high carbon resistance, hence avoiding the catalyst deactivation during the reaction. The development of mesoporous Ni(OH)2/CeNixOy composites catalyst has been established through a hydrothermal method as described in Dou, J et al's work . Indeed, due to the thermal treatment at 500°C, Ni(OH)2 was reduced to Ni nanoparticles Ni NPs. The size of Ni NPs was in perfect correlation to the Ni loading, which means as the charge of Ni increases, the size of Ni NPs follows the same trends. Catalysts 0.4 Ni/CeNixOy and 0.5 Ni/CeNixOy, which means Ni/(Ni+Ce) ratios of 0.4 and 0.5 respectively, showed the best catalytic properties for DRM reaction than the other ratios especially 0.6 and 0.8. This might be attributed to the good dispersion of Ni NPs with the smallest size (10 nm). Therefore, due to the strong exchanges between dispersed Ni NPs and CeNixOy, 0.5 Ni/CeNixOy catalyst exhibited good stability for DRM up to 140 h. In 2021, Zhang, X et al tested diverse Ni-Co bimetallic catalysts supported over θ-Al2O3 as a highly active, selective, and stable catalyst for dry methane reforming at 700°C in a static bed reactor. In general, 10 wt% Co/θ-Al2O3 shows low activity than the bimetallic catalyst 5wt%Ni-5wt%Co/θ-Al2O3 for DRM. This superiority might be due to low bimetallic charges, its small particle size, and as well as the contribution of synergistic effects of the catalyst components. While 5wt%Ni-5wt%Co/θ-Al2O3 exhibited superior performance than 10 wt% Co/θ-Al2O3, it presented a deficiency from catalyst poisoning due to extensive coking under DRM. So, it was discovered that 10 wt% Ni/θ-Al2O3 exhibited the highest stability under 100 h time-on-stream, for which H2 yield decreased from 56% to 45%. Also, it does not present any trace of catalyst sintering. Therefore, the superior performance of 10 wt% Ni/θ-Al2O3 was attributed to its appropriate metal oxide particle size, electronic nickel properties, and as well as higher reducibility of nickel over θ-Al2O3 support. Moreover, a NiAl2O4 was obtained over Ni/Al2O3 by increasing the final calcination temperature to 900°C as reported in Zhou, L et al's paper . So, a catalyst with strong metalsupport exchanges was engineered, which shows high catalytic performance with high catalytic resistance to sintering and coking at 700 °C under 100 h DRM operation. Also, as reported in Han, J.W et al's work a highly active and coke-resistant Ni-based catalyst was designed by using (5.2 nm) Ni NPs immobilized over functionalized SiO2 support. Ni/SiO2 catalyst coated with SiO2 overlayers exhibited superior catalytic activity and stability up to 170 h of DRM operation without any deactivation of the catalyst. Indeed, physicochemical analysis demonstrates that SiO2 overlayers enable the transfer of both reactants and products while avoiding aggregation of the Ni NPs. However, the uncoated Ni/SiO2 presented severe sintering, and the establishment of filamentous carbon was noticed after the DRM reaction. Recently, Chai,Y et al developed La0.46Sr0.34Ti0.9Ni0.1O3 (LSTN0.1) a perovskite-type catalyst with a bimodal size distribution of Ni particles through a combustion route. Subsequently, LSTN0.1 was used for catalytic dry reforming of methane under mild conditions (CH4:CO2 = 1:1.2 at 700°C). In this condition, no carbon deposition was noticed on the catalyst layer (LSTN0.1). However, under harsh conditions (CH4:CO2 = 2:1 at 700°C), the coking process speeded up on the catalyst layer (LSTN0.1). Furthermore, it was noticed that this bimodal Ni catalyst with a huge amount of small particles possesses higher coke resistance than the catalyst with few small particles. Also, it was found that large Ni particles (14.5 nm average size) are more exposed to the coking effect, whereas small Ni particles (2.5 nm) stayed unchanged. So, as issued here and in several other research articles, nickel-based catalysts deserve advanced properties for dry reforming of methane. Nickel-based catalysts can be extended in diverse electrocatalytic and catalytic and as well as environmental industrial applications. Hence, in the next section, it will be focused on the lasted development of Ni-based catalysts for catalytic oxidation reactions (COR).
