Abstract

The efficiency of photocatalytic pollutant removal largely depends on the ability of the photocatalytic system to produce hydroxyl radicals (•OH). However, the capability of photocatalyst to produce •OH is not strong at present. Advancing the capacity of photocatalytic system to produce •OH has always been a tough problem and challenge in the field of environmental science. In this research, it was found that introducing nitric oxide (NO) into the graphitic carbon nitride (g-C₃N₄) photocatalytic system could memorably enhance the ability of producing •OH group. This study provides a new idea for improving the capacity of photocatalytic •OH production.
