Defective ReS Triggers High Intrinsic Piezoelectricity for Piezo-Photocatalytic Efficient Sterilization.

Rhenium disulfide (ReS) is a promising piezoelectric catalyst due to its excellent electron transfer ability and abundant unsaturated sites. The 1T' phase structure leads to the evolution of ReS into a centrosymmetric spatial structure, which restricts its application in piezoelectric catalysis. Herein, we propose a controllable defect engineering strategy to trigger the piezoelectric response of ReS.
