In August 2020, Li, Y.T et al reported a hierarchical porous CuNi bimetal-organic framework as a highly active catalyst for the hydrolysis degradation of AB to hydrogen gas. H2 production from AB hydrolysis. Using diverse techniques, it is confirmed that CuNi-MOFs display outstanding performance including catalytic activity and as well as amazing durability for hydrogen release via hydrolytic dehydrogenation of AB. These features allow CuNi-MOFs to deliver a turnover frequency of (40.85 molH2/molmetal min) with an apparent activation energy of (28.99 kJ/mol), making it the strongest catalyst among many scientific reported catalysts including Ni/Pt catalysts, Pt catalyst, Ni/CNTs engineered by ALD method, Ni@h-BN, Co-Ni-P/Pd-TiO2, Ni-M@HAP, and so forth. Therefore, due to the availability of copper and nickel, their affordable cost, and the facile solvothermal route of these CuNi-MOFs, as well as the enhanced catalytic performances, it seems that CuNi-MOFs might be considered a promising candidate catalyst for AB hydrolysis to H2 gas and as well as other applications. In March 2020, Ozkar, S published a review article related to the use of transition metal (0) nanoparticles as an active catalyst for the methanolysis of AB to release dihydrogen gas. Several metal catalysts have been discussed in his study including Co (0), Cu (0), Ni (0), Pd (0), and Rh (0) highly dispersed and stabilized over diverse matrixes within the void spaces of zeolite, nano-SiO2, nano-Al2O3, nano-HAP, nano-CeO2, and so forth. It is noticed that Ni (0), Ru (0), and Pd (0) nanoparticles, stabilized as colloidal and dispersed in methanol are extremely active and durable catalysts for AB methanolysis. The embedded TM (0) NPs on the surface of solid materials displayed significantly enhanced catalytic features (catalytic activity, durability, recyclability, and so forth). It is carefully ascribed that Rh (0) NPs anchored over a wide range of oxides supports revealed to be powerfully active in the H2 production from the methanolysis of AB. Especially, Rh (0) NPs/nano-Al2O3 shows the highest TOF among these oxide-supported Rh (0) NPs, with a TOF value up to 218 min -1 . At room temperature of H2 release from AB, a long-lived with a full turnover value as high as 26,000 was noted. Also, it is specified that AgPd bimetallic alloy NPs deposited over conductive carbon give the best catalytic activity in producing H2 from the AB methanolysis. In short, as carefully shown by these articles, Ni-based materials anchored on diverse kinds of matrixes stand to be a potential candidate for active, selective, stable, and as well as a reusable catalyst with suitable activation energy and higher turnover frequency for hydrogen release from the hydrolytic dehydrogenation of ammonia-borane, and we believe that these Ni-based catalysts can be useful for other hydrolysis reactions. So, section five will be focused on the newest research published papers on Ni-based catalysts for the catalytic hydrogenation reactions.
