Effect of contact interface between TiO2 and g-C3N4 on the photoreactivity of g-C3N4/TiO2 photocatalyst: (0Â 0Â 1) vs (1Â 0Â 1) facets of TiO2

Direct Z-scheme g-C3N4/TiO2 hybridized photocatalyst shows superior photocatalytic activity by contacting g-C3N4 with exposed (1 0 1) facets due to efficient removal of the photo-generated electrons accumulated on (1 0 1) facets of high-energy TiO2.
