Active Facets on Titanium(III)-Doped TiO2: An Effective Strategy to Improve the Visible-Light Photocatalytic Activity

Partially reduced TiO2 with highly active facets has been fabricated: Ti3+ was successfully incorporated without any additional reducing agent and surfactant, and highly active facets developed preferentially. The product shows improved photocatalytic activity in H2 production over previously report...

Description
Summary:Partially reduced TiO2 with highly active facets has been fabricated: Ti3+ was successfully incorporated without any additional reducing agent and surfactant, and highly active facets developed preferentially. The product shows improved photocatalytic activity in H2 production over previously reported material. Photocatalytic activity over an extended time period demonstrates the stability of reduced TiO2 made by this approach.
