| 英文摘要 | One of the major challenges encountered in CO2utilization is the development of available and cost-efficient catalysts with sufficient activity, selectivity, and stability for the generation of useful methane. Here, conductive black titania, TiO2−x, is found to be efficient in photocatalyzing the reduction of CO2to CH4. This unique material comprises a crystalline core–amorphous shell structure (TiO2@TiO2−x) with numerous surface oxygen vacancies, which facilitates the adsorption and chemical activation of CO2molecules. Under full solar irradiation, the optimized 500-TiO2−xmaterial with narrowed band gap and intermediate states below the conduction band tail exhibits a high space-time yield of CH4of 14.3 μmol g−1h−1, with 74 % selectivity and excellent photostability. The present findings can make a significant contribution, not only to develop the surface electron-modified black TiO2catalyst to boost photocatalytic efficiency, but also to establish a really viable and convenient CH4production process for CO2conversion and renewable solar energy storage. © 2017 Wiley-VCH Verlag GmbH & Co.
