Customized Ultrathin Oxygen Vacancy‐Rich Bi ₂ W _0.2 Mo _0.8 O ₆ Nanosheets Enabling a Stepwise Charge Separation Relay and Exposure of Lewis Acid Sites toward Broad‐Spectrum Photothermal Catalysis (Small 51/

Photothermal Catalysis More in article number 2404579, Min-Quan Yang, Qingrong Qian, and co-workers designed a two-dimensional ultrathin oxygen vacancy (Ov)-rich Bi2W0.2Mo0.8O6 catalyst is designed, which realizes stepwise charge separation, exposure of abundant active Lewis acid sites, and extending of light absorption. Especially, the introduction of Ov induces a significant solar heating effect, providing additional thermal energy to accelerate photocatalytic processes, ultimately contributing to a higher photothermal catalytic activity.
