CuAg nanoparticles immobilized on biomass carbon nanospheres for high-efficiency hydrogen production from formaldehyde

A low-cost and high-efficient catalyst (denoted as CuAg/BC) was fabricated by immobilizing Cu-Ag bimetal on green and renewable biomass carbon nanospheres derived from sucrose for the first time. The prepared CuAg/BC catalyst exhibited high catalytic activity and stability toward the dehydrogenation...

Description
Summary:A low-cost and high-efficient catalyst (denoted as CuAg/BC) was fabricated by immobilizing Cu-Ag bimetal on green and renewable biomass carbon nanospheres derived from sucrose for the first time. The prepared CuAg/BC catalyst exhibited high catalytic activity and stability toward the dehydrogenation of formaldehyde at 30 °C. The rate of H2 generation can reach 306.7 mL min−1 g catalys−1, which is among the highest values reported so far. The superior catalytic performance is derived from that the synergistic effect between Cu and Ag nanoparticles, and the relatively small size of CuAg nanoparticles greatly increased the utilization efficiency of the metals. [Display omitted] •Cu and Ag nanoparticles were successfully immobilized onto carbon spheres.•Cu-Ag/BC exhibits high activity for the dehydrogenation of formaldehyde.•The initial rate of hydrogen generation was 306.7 mL min−1 g catalys−1.
