چکیده انگلیسی
The nanostructured NiB catalysts were synthesized on the Cu sheet by electroless plating at ambient temperature. The catalytic performance for hydrogen generation from hydrolysis of sodium borohydride solution has been investigated. The concentration of the reducing agent was shown to have a significant influence on the hydrogen generation performance. The NiB catalyst deposited with 0.08 g Lâ1 reducing agent showed excellent catalytic activity due to the smaller particle or crystal size and the higher surface roughness. The highest hydrogen generation rate could reach 4991.8 mL minâ1 gâ1 and the lower activation energy was 36.3 kJ molâ1. The NiB catalyst also displayed high stability. The catalytic activity could retain about 80.5% of its initial value after 5 cycles.
