- Abstract
Selective hydrogenation of biomass-derived maleic anhydride (MAH) to succinic anhydride (SA) is valuable but remains a challenge due to the complicated reaction network. We here report that single Pt atoms decorated onto the edges of two-dimensional (2D) 1T-phase MoS2 (Pt1/1T-MoS2 SAC) as a proof-of-concept catalyst can efficiently convert biomass-derived MAH to SA with 100% conversion and 100% selectivity under mild conditions. The kinetic data and characterization results suggest that the catalytic performance of the edge-anchored Pt1/1T-MoS2 SAC originates from the facile H2 dissociation induced by the electron-deficient Pt1 atoms and the pocket-like configuration of Pt1 active site confines the adsorption configuration of MAH by the steric effect. The strategy of fabricating edge-confined catalysts offers a new direction to design novel SACs for biomass-derived transformations.
