Abstract

Abstract : Novel conjugated microporous polymers for photocatalytic hydrogenation and oxidation reactions of biomass derived chemicals with efficient utilization of natural sunlight have been demonstrated. Abstract : Photocatalytic conversion of biomass derived chemicals to valuable products is a highly sustainable process. Herein we report the photocatalytic hydrogenation of maleic acid to succinic acid and oxidation of 5-hydroxymethylfurfural to 2, 5-diformylfuran using the same conjugated porous polymers (CMPs). The CMPs were constructed from 2, 4, 6-(tri-2-thienyl)-1, 3, 5-triazine as the knots and different benzene derivatives as linkers, and their morphologies, redox potentials, charge separation efficiency, and the consequent photocatalytic performance have been controlled. As a result, the CMP with benzene as the linker features the highest photocatalytic activities with production rates of 4.66 mmol g −1 h −1 for succinic acid and 0.53 mmol g −1 h −1 for 2, 5-diformylfuran, respectively. Most importantly, high photocatalytic activity has also been achieved under natural sunlight irradiation, implying its feasibility as an efficient photocatalytic platform for solar-to-chemical energy conversion.
