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

The high-entropy perovskite, i.e. La(FeCoNiCrMn)O 3 , was prepared for simultaneous CO 2 reduction and biomass upgrading. An excellent CO evolution rate of 131.8 μmol g −1 h −1 and an xylonic acid yield of 63.9% were gained.
