New strategies of Designing Nickel-based Multifunctional Materials for Various Catalytic Applications: New advances

The search for new avenue of designing of novel candidate materials is on the cutting edges research and nanotechnology fields. Highly active, selective and as well as stable materials are required for many catalysis and environmental applications. These avenues include, both simulation and physicochemical methods. Indeed, in the past few decades, the utilization of Ni based materials for nickel composite catalysts synthesis have grown exponentially, as they exhibit powerful catalytic performances. Ni-based catalysts anchored on various forms of matrixes like (Carbons, Polymers, metal oxides, metal carbide, metal sulphide, zeolite, and so fourth) revealed themselves to possess high intrinsic catalytic activity, selectivity and fully stable for hydrogen (H2) release from diverse sources as (Ammonia, and Amine) borane, water splitting, hydrogen iodide, and so on. Also, nickel-based catalysts deserve advanced properties for dry reforming of methane (DRM). Furthermore, Ni-based materials have enhanced properties for several catalytic oxidation reactions including oxygen evolution (OER), alcohol oxidation (AOR), hydrogen oxidation reactions (HOR), and so forth. It is explained that, Ni NPs anchored over aluminosilicates seems to be a perfect model catalyst for organic sulfur removal through the catalytic adsorption process, and also might be extended to other catalysis and environment applications. Hence, it is taught that the upcoming research careers can be deeply focused on these aspects: i) making bimetallic catalysts, ii) the use of a promoter, iii) the use of three distinct supports for a catalyst, and the last one is to fully consider the design route of the catalyst as each method has its unique benefits. Therefore, these aspects will affect the performance of the resulting materials, which will lead to raise the Ni active site, low-temperature processability, and excellent resistance to coke, deactivation, and as well as sintering effects over Ni-based catalysts. These will lead to a suitable advantages for catalyst engineering and their related applications, as Ni-based materials are cost-effective as compared to platinum based materials.
