Abstract In this study, the effect of Co-Cr(0) and Co-Cr-B nanocatalysts on sodium borohydride hydrolysis was investigated. The extract obtained from pods bean plant produced using environmentally friendly green synthesis method, along with chemical reduction method as production procedure for catalysts. analyses used to study structure surface morphology catalysts are SEM, TEM, EDX, XRD, FTIR, XPS. From SEM TEM pictures, shape comprises tiny spheres has a porous nanostructure, particle size is 35–40 nm. XRD investigation revealed that had an amorphous structure. catalysts’ been confirmed include components Co, Cr, B EDX XPS analyses. It examined how different amounts catalyst, NaBH 4 /NaOH concentrations, solution temperatures affected borohydride. n-th order kinetic model utilized determine activation energies nanocatalysts, which were found be 24.39 kJ/mol 43.09 kJ/mol, respectively. Also, turnover frequency (TOF) values synthesized at 60 °C calculated 19,210 mLmin − 1 g 12,410 , repeatability in showed high activity even after fifth use. Graphical
