The basic aim of this study is to develop a feasible new catalyst system for the hydrogen generation by catalytic hydrolysis of NaBH4. The method is an alternative approach for the hydrogen production with metal catalysts. Ni–Co bimetallic complex catalysts with different Co–Ni contents were derived from 4-4'-methylene bis (2,6-diethyl)aniline-3,5-di-tert-butylsalisilaldimin ligand and their catalytic performances were investigated with hydrogen generation by catalytic hydrolysis of NaBH4. Experimental results showed that the Co–Ni contained catalysts exhibited much higher activity than the monometallic complex catalyst. The optimal mixture percentage of Co–Ni complex catalyst was 80:20. It was found that a combination of 2.5 wt% NaBH4 solution concentration and 5 wt% NaOH yields the highest performance for the hydrogen generation. The catalysts were characterized by XRD, FT-IR and SEM techniques.eninfo:eu-repo/semantics/openAccessBimetallic Co–Ni based complex catalyst for hydrogen production by catalytic hydrolysis of sodium borohydride with an alternative approachArticleQ12-s2.0-84997113423
