- W2379926438 abstract "Honeycomb-like hierarchical porous carbon was prepared and employed as substrate to support nickel nanparticles via an impregnation-chemical reduction method.The synthesized carbon-supported nickel(denoted as Ni/C) was used as catalysts for hydrogen generation from hydrolysis of ammonia borane(AB).Results of XRD,BET,SEM,Raman,and TEM measurements showed that the synthesized carbon possessed high specific surface area of 737 m2·g-1and partially graphited structure;the supported amorphous Ni nanoparticles had an average particle size of 10 nm and were uniformly dispersed on the porous carbon substrate.The synthesized Ni/C exhibited high catalytic activity towards the hydrolysis of AB.At hydrolysis temperature of 298 K,Ni/C with30wt% Ni loading was the most active,resulting in a high hydrogen release rate of 1 304.67 m L·min-1·g-1and a low activation energy of 29.1 k J·mol-1.In addition,the Ni/C catalyst could be repeatedly utilized with respectable activity reservation for several times.The results indicate that Ni/C is a promising low-cost catalyst for hydrolytic dehydrogenation of AB." @default.
