Abstract

original image

Small and active: Co nanoparticles supported on graphitized activated carbon are highly stable and selective for acetone steam reforming. DFT calculations were performed to analyze the reaction mechanism. The present work provides insight into the rational design of catalysts that can selectively oxidize species arising from C[BOND]C bond cleavage of biomass-derived oxygenates to maximize H2 selectivity and minimize the formation of coke and methane.
