Base-free hydrogen generation from formaldehyde and water catalyzed by copper nanoparticles embedded on carbon sheets

Abstract

Catalytic dehydrogenation from formaldehyde and water provides a promising pathway to produce the renewable and clean energy resource of hydrogen. Copper-based heterogeneous catalysts show promises to catalytically generate hydrogen from formaldehyde. However, those catalysts incompletely dehydrogenate formaldehyde into formic acid and hydrogen in the presence of base, leading to only partial utilization of carrier. Herein, we report a simple and facile synthesis of uniform Cu nanoparticles embedded on carbon sheets (Cu@CS), which enable hydrogen generation through the complete dehydrogenation between formaldehyde and water in the absence of any additives under mild reaction conditions. The exceptional performance is linked to the unique embedded structure of catalysts by confining Cu nanoparticles within carbon sheets as well as the strong interaction between Cu and supports.
