Co-B catalyst supported over mesoporous silica for hydrogen production by catalytic hydrolysis of Ammonia Borane: A study on influence of pore structure

- Co-B catalyst particles were supported over three type of mesoporous silica of different pore sizes.
- Co-B supported over SBA-15 showed highest H2 generation rate for hydrolysis of AB.
- Confinement of Co-B within the pores creates smaller NPs (6 nm) with uniform size distribution.
- Thicker pore walls of SBA-15 avoid agglomeration of Co-B NPs at elevated temperature (873 K).
