Oxygen vacancy-engineered titanium-based perovskite for boosting H₂O activation and lower-temperature hydrolysis of organic sulfur.

ABSTRACT: Modulation of water activation is crucial to water-involved chemical reactions in heterogeneous catalysis. Organic sulfur (COS and CS₂) hydrolysis is such a typical reaction involving water (H₂O) molecule as a reactant. However, limited by the strong O-H bond in H₂O, satisfactory CS₂ hydrolysis performance is attained at high temperature above 310 °C, which is at the sacrifice of the Claus conversion, strongly hindering sulfur recovery efficiency improvement and pollution emissions control of the Claus process. Herein, we report a facile oxygen vacancy (V_O) engineering on titanium-based perovskite to motivate H₂O activation for enhanced COS and CS₂ hydrolysis at lower temperature. Increased amount of V_O
