Boosting mineralized organic pollutants by using a sulfur-vacancy CdS photocatalyst.

Photocatalytic mineralization of organic pollutions and simultaneously converting CO to CO (tetracycline → CO → CO) represents a fascinating way to solve the environmental and energy crisis. This work demonstrates the excellent mineralization and CO reduction performance of S-vacancy CdS and reveals the high efficiency of the carbon self-recycling two-in-one photocatalytic system.
