Synthesis and photocatalytic properties of visible-light-responsive, three-dimensional, flower-like La-TiO/g-CN heterojunction composites.

We prepared a new three-dimensional, flower-like La-TiO/g-CN (LaTiCN) heterojunction photocatalyst using a solvothermal method. Analysis and characterization were performed by conducting scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform-infrared spectroscopy, ultraviolet-visible spectrophotometry, and nitrogen adsorption and desorption. The prepared g-CN nanosheets could reach 100 nm in size and covered the TiO surface.
