• )–CaTiO3 (CTCN) organic–inorganic heterojunction photocatalyst was synthesized by a facile mixing method, resulting in the deposition of CaTiO3 (CT) nanoflakes onto the surface of g-C3N4 nanosheets. The photocatalytic activity of the as-synthesized heterojunction (along with the controls) was evaluated by

In addition, the two-dimensional (2D) morphology of g-C3N4nanosheets and CT nanoflakes provides enough reaction sites due to their larger surface area and enhances the

• such materials possess a large surface area, providing abundant active sites for reaction, and the short bulk diffusion length reduces the probability of recombination of the photogenerated charges. Herein, we report the optimized synthesis of sheet-like 2D CT nanoflakes for the first time via the
