A review on the effects of TiO₂ surface point defects on CO₂ photoreduction with H₂O Academic Article

abstract

• 2016 The Chinese Ceramic Society Photocatalytic reduction of CO2with water by photocatalysts such as TiO2to produce solar fuels is an attractive approach to alleviate the environmental influences of greenhouse gases and in the meantime produce valuable carbon-neutral fuels. Among the materials properties that affect catalytic activity of CO2photoreduction, the point defect on TiO2is one of the most important but not frequently addressed and well understood in the literature. In this review, we have examined the major influences of TiO2point defects on CO2photoreduction with H2O, by changing the catalysts' gas adsorption capabilities, optical properties, and electronic structures. In addition, the performances of various defective TiO2toward CO2photoreduction are summarized and compared in terms of productivity, selectivity, and stability. We hope this review can contribute to understanding the mechanism of CO2photoreduction on defective TiO2and provide insights to the design of highly efficient defect-rich TiO2to boost the CO2utilization.
