Optimal Structure and Photocatalytic Performance of C3N4@TiO2 Composite by Controlling the Molar Ratio of Components

“…The lattice spacing of 0.35 nm corresponding to the (101) crystal facets of anatase-type TiO 2 , and a lattice spacing of 0.32 nm derived from the (002) crystal plane of C 3 N 4 . Moreover, obvious interlacing of lattice fringes can be detected from the HRTEM image, indicating an effective recombination between C 3 N 4 and TiO 2 . , That is to say, the uniform TiO 2 coating is obtained after water bath reaction, which is also reported in our previously published literature …”

“…Due to its graphene-like layered structure and unique electronic properties, graphitic carbon nitride (g-C 3 N 4 ) has gained recognition as a promising candidate for photocatalysis, particularly in the degradation of environmental pollutants. − The two-dimensional planar structure with a conjugated system has facilitated charge carrier transport, and its narrow bandgap energy of approximately 2.7 eV has endowed it with the capability to absorb visible light of up to 475 nm. Additionally, g-C 3 N 4 exhibits remarkable properties such as excellent thermal and chemical stability, affordability, and easy control of the energy band structure.…”
