Title: Catalyst for hydrogen production
Inventor: MORISHITA MASAO
IPC: B01J27/22
Filed: 2021-10-20
Abstract: To stably produce hydrogen from an ammonia borane which is a hydrogen-containing compound storing a high concentration of hydrogen with high efficiency.SOLUTION: A catalyst for hydrogen production, which is used for producing hydrogen from an ammonia borane (NH3BH3), is made of a tungsten carbide which is a carbide of cobalt solid solution tungsten alloy powder having ferromagnetic cobalt (Co) solidified into solution in a tungsten grating (W) and a given internal magnetic field having a Co-W-C solid solution phase included to be ferromagnetic. The ferromagnetic tungsten carbide realizes high catalytic activity, and functions as a catalyst for hydrogen production, which is used for generating hydrogen from the ammonia borane. In the tungsten carbide including the Co-W-C solid solution phase, cobalt is made a nonequilibrium forced solution in the tungsten grating to be a uniform solid solution in a cobalt grain boundary, thus increasing the catalytic activity.SELECTED DRAWING: Figure 2
