Construction of a 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 the photoenzyme in the prepared composites, a remarkable CO (27.15 μmol g_cat⁻¹ h⁻¹) and CH₄ (64.88 μmol g_cat⁻¹ h⁻¹) production rate and a benzaldehyde yield of 84.1% were gained.
