Co-B Nanoparticles Supported Over FSM Type Mesoporous Silica: An Efficient Nanocatalyst for Hydrogen Production by Hydrolysis of Ammonia Borane

摘要

Chemical impregnation-reduction method was used to synthesize nanocatalyst in the form of Co-B nanoparticles (NPs) supported over FSM type mesoporous silica. The catalytic activity of the nanocatalyst was tested for hydrogen production using Ammonia Borane as a source. TEM showed that Co-B NPs are located into the pores with average size of 2.5 nm, while XRD confirmed the amorphous nature of the catalyst powder. The pore coverage by Co-B NPs was established by BET surface area measurement. H_2 generation rate of FSM supported Co-B NPs was found to be significantly superior than that of unsupported and nonporous silica supported Co-B catalyst.
