Abstract
, which produces more pronounced cyano groups under high-temperature calcination and alkaline environment while promoting the formation of N vacancies. This design effectively promotes the separation of electron-hole pairs and the optimization of carrier transport capacity, and as a result, KOH doping exhibits better photocatalytic performance. The current work provides a more favorable modification strategy for future solar energy conversion.
