In the process of developing low cost, high activity, and high selectivity catalysts for selective hydrogenation of benzene acetylene . How to combine high activity and selectivity of catalysts has been a major challenge in this field. Metals with catalytic activity for alkyne hydrogenation are mainly Pd , Au , Ni , Fe , Pt , and Cu . In recent years, the research on catalysts for selective hydrogenation of alkynes has been further deepened, and the research direction has shifted to the development of more environmentally friendly and efficient catalysts. There are mainly two kinds of hydrogenation catalysts: One is the noble metal catalyst, such as Pt , Pd based alloy nanoparticles, etc. The other is non-noble transition metal catalysts such as Raney Ni , Cu 34-37 catalyst, etc. Among the noble metal catalysts, supported Pd catalyst has a high conversion rate for selective hydrogenation of phenylacetylene . While for the non-noble metal catalysts, Ni-based catalysts are typical, which have attracted much attention due to their low cost and good catalytic hydrogenation performance . Donphai reported the synthesis of a mesoporous silica (MS) support Ni-carbon nanofibers (CNFs) catalyst. First, the MS support was prepared by modifying the pore size of SBA-15 mesoporous silica using a swelling agent, 1,3,5-trimethylbenzene (TMB). After that, nickel nanoparticles were loaded onto the MS support via an impregnation method, and Ni-CNFs were consecutively synthesized using nickel nanoparticles in the catalytic chemical vapor deposition (CCVD) process. The obtained Ni-CNFs/MS catalyst with unique composite structure, which shows excellent catalytic performance than Ni/MS. Panwar 43 synthesized polyaniline/graphene oxide composites by liquid-liquid interface polymerization of aniline in a sulfonated graphene oxide suspension using hydrogen peroxide and ferric chloride as oxidants. Nanonickel was then decorated on the synthetic hybrid material and used for hydrogenation of phenylene and its derivatives at room temperature and hydrogen pressure. And the yield of styrene reached 82%. The synthesized hybrid catalyst had good catalytic activity and was recovered by centrifugation at the end of the reaction. There was no obvious loss of catalytic activity after several cycles. Using SiH4 as a silicon source, Chen 44 prepared nickel-silicon intermetallic compounds by direct silicification. The interaction between nickel and silicon in nickel silicide led to a strong modification of the electronic structure around the Fermi level compared to the metallic Ni, which caused good selective hydrogenation of phenylacetylene to styrene. Using carbon template, silicide oxides, and SiH4/H2, Chen 45 successfully synthesized nano-silicide modified nickel catalyst with significant catalytic activity and high selectivity for hydrogenation of benzene acetylene. The XRD, magnetic measurements, HRTEM, and EDX confirmed the formation of NiSix which involved the following sequence: Ni (cubic) →Ni2Si (orthorhombic) →NiSi (orthorhombic) → NiSi2 (cubic), with the increasing siliconized temperatures. They found that Si atoms reside in the gaps between Ni atoms, which changed the crystal lattice of the nickel unit cell and further affected the activity of the catalyst and the selectivity of the product. As it is well known that the catalyst's support has a great effect on the catalytic reactivity, stability, and selectivity. Hence, the development of a cost-effective, more stable, and sustainable support carrier is of great importance.
