Photothermal Catalysis: Enhanced Solar Photothermal Catalysis over Solution Plasma Activated TiO₂ (Adv. Sci. 16/2020)

In article number 2000204, Changhua Wang, Xintong Zhang, and co-workers demonstrate a solution plasma strategy to introduce H dopant into oxygen vacancy type TiO2. The combination of H dopant and oxygen vacancy endows a 300 times higher conversion rate for CO2 reduction with H2O. The H dopant is believed to bridge the gap between oxygen vacancy and the conduction band, resulting in extraction of trapped electrons at oxygen vacancy to the conduction band in photothermal catalysis.
