Abstract
TiO2−x/W18O49with core-shell or double-shelled hollow microspheres were synthesized through a facile multi-step solvothermal method. The formation of the hollow microspheres with a double-shell was a result of the Kirkendall effect during the solvothermal treatment with concentrated NaOH. The advanced architecture significantly enhanced the electronic properties of TiO2−x/W18O49, improving by more than 30 times the CO2photoreduction efficiency compared to the pristine W18O49.OperandoDRIFTS measurements revealed that the yellow TiO2−xwas a preferable CO2adsorption and conversion site.
