The in situ Ni and Ni0.5Fe0.5 nanoparticles exhibited considerable catalytic activity but suffer from severe activity degradation when they are isolated from reaction solution and subjected to post treatment including washing, drying and annealing.
The nanoporous Ni1-xPtx (x = 0.01, 0.08 and 0.19) catalysts, which are synthesized ex situ via a Ni-Pt replacement route, show significantly enhanced catalytic performance.
-> The synthesized nanoporouse Ni0.81Pt0.19 afforded a high hydrogen release rate.
The nanoporouse Ni0.99Pt0.01 that feature low Pt content result in respectable activity with high hydrogen generation efficientcy and low activation energy
The result indicated potential application of nanostactured Ni-based catalysts for on-borad hydrogen storage/production from AB hydrolysis.
