Plasmonic Au Nanoparticle of a Au/TiO2–C3N4 Heterojunction Boosts up Photooxidation of Benzyl Alcohol Using LED Light

OH) act as the reactive oxygen species during photooxidation. Furthermore, the experimental results combined with density functional theory calculations reveal that the chemisorbed benzyl alcohol population, surface oxygen vacancies, and lifetime of photoexcited electrons and holes are largely improved by plasmonic Au NPs. This study on nanogold composites provides some hints for developing new efficient and practical photocatalysts.
