The photocatalytic valorization of glucose has attracted more and more attention for producing value-added chemicals. Herein, value-added chemicals like arabinose and formic acid were obtained by selective photocatalytic oxidation of glucose irradiated with visible light, which was realized using Bi2O3/TiO2 composite as the photocatalyst and atmospheric O2 as the oxidant in water. It was found that the photocatalytic performance of Bi2O3/TiO2 composite in the glucose oxidation was obviously superior to that of pure Bi2O3 and pure TiO2, the significantly enhanced photocatalytic efficiency was m...
