Dr. Xiaxi Yao as the first author from School of Materials Engineering recently published research paper entitled “Mie resonance in hollow nanoshells of ternary TiO2-Au-CdS and enhanced photocatalytic hydrogen evolution” in Applied Catalysis B: Environmental (IF:16.683). This work designed a ternary TiO2-Au-CdS photocatalyst with controllable Mie scattering peak for the first time to verify if matching the Mie scattering peak with the absorption peak of semiconductors could greatly improve their photocatalytic performances under visible light irradiation. By varying the inner diameter of TiO2 nanoshell from 150 to 255 nm, the Mie scattering peak was controlled from below 370-510 nm. When the Mie scattering peak of TiO2 nanoshell (inner diameter = 185 nm) matches the absorption band of CdS, a highest visible-light photocatalytic hydrogen production rate was observed among all the ternary photocatalysts with different inner diameters. The backscattering calculation based on Mie’s theory and the comparison of photocatalytic performances of different composite catalysts including TiO2, TiO2-Au, and TiO2-CdS hollow nanoshells also confirmed that the scattering phenomenon in hollow nanoshells is beneficial for photocatalysis. This work may favor various technological applications of Mie scattering for effective light utilization.
