Construction of Laccase/CeO2/attapulgite nanocomposite for photoenzymatic catalytic CO2 reduction coupled with biomass oxidation

Abstract

Herein, a photoenzymatic synergistic catalytic material, i.e. Laccase/CeO2/attapulgite, was prepared for simultaneous CO2 conversion and biomass conversion. Based on the synergistic effect of photoenzyme in the prepared composites, a remarkable CO (27.15 umol gcat-1 h-1) and CH4 (64.88 umol gcat-1h-1) production rateand a benzaldehyde yield of 84.1% were gained.
