TiOF2/g-C3N4 composite for visible-light driven photocatalysis

A novel TiOF2/g-C3N4 composite was obtained by hydrothermal formation of TiOF2 when g-C3N4 powders were present. The performance of relevant samples in photocatalysis was studied under visible light. The efficiencies of the photocatalysts in degrading Rhodamine B followed the sequence of TiOF2/g-C3N4 > TiO2/g-C3N4 > g-C3N4 > TiOF2. In water splitting using Pt as a co-catalyst and triethanolamine (TEOA) as a sacrificial agent, the efficiencies followed the same sequence. Various tools were used to characterize the structures of the photocatalysts and understand the reasons for the superior performance of TiOF2/g-C3N4. Photocatalytic mechanisms involving TiOF2/g-C3N4 were proposed.
