A green and highly efficient visible-light-driven synergistic photoelectrochemical (PEC) catalysis system was systematically demonstrated for selective oxidation of biomass alcohols to the corresponding aldehydes in an O₂ atmosphere under the mild conditions by employing the Au/CeO₂–TiO₂ NTs as photocathodes. Results showed that the conversion of benzyl alcohols was as high as 98% and the selectivity of benzaldehyde was >99% at the bias potential of −0.8 V under the visible light irradiation for 8 h…
