Noble Metal-Free TiO₂-Coated Carbon Nitride Layers for Enhanced Visible Light-Driven Photocatalysis.

ABSTRACT: Composites of g-C₃N₄/TiO₂ were one-step prepared using electron impact with dielectric barrier discharge (DBD) plasma as the electron source. Due to the low operation temperature, TiO₂ by the plasma method shows higher specific surface area and smaller particle size than that prepared via conventional calcination. Most interestingly, electron impact produces more oxygen vacancy on TiO₂, which facilitates the recombination and formation of heterostructure of g-C₃N₄/TiO₂. The composites have higher light absorption capacity and lower charge recombination efficiency. g-C₃N₄/TiO₂ by plasma can produce hydrogen at a rate of 219.9 μmol·g^-1·h^-1 and complet
