| 中文摘要 | The catalyst with high activity and durability plays a crucial role in the hydrogen generation systems for the portable fuel cell generators. In the present study, a ruthenium supported on graphite catalyst (Ru/G) for hydrogen generation from sodium borohydride (NaBH(4)) solution is prepared by a modified impregnation method. This is done by surface pretreatment with NH(2) functionalization via silanization, followed by adsorption of Ru (III) ion onto the surface, and then reduced by a reducing agent. The obtained catalyst is characterized by transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS). Very uniform Ru nanoparticles with sizes of about 10 nm are chemically bonded on the graphite surface. The hydrolysis kinetics measurements show that the concentrations of NaBH4 and NaOH all exert considerable influence on the catalytic activity of Ru/G catalyst towards the hydrolysis reaction of NaBH(4). A hydrogen generation rate of 32.3 L min(-1) g(-1) (Ru) in a 10 wt.% NaBH(4) + 5 wt.% NaOH solution has been achieved, which is comparable to other noble catalysts that have been reported.
