Entropy engineering of La-based perovskite for simultaneous photocatalytic CO2 reduction and biomass oxidation

Herein, the high-entropy perovskite, i.e. La(FeCoNiCrMn)O3, was prepared for simultaneous CO2 reduction and biomass upgrading. Based on the synergistic effect between the elements in the high-entropy material, an excellent CO evolution rate of 131.8 μmol g-1 h-1 and a xylonic acid yield of 63.9% were gained.
