Tailored highly efficient Co-doped TiO2/CoTiO3 heterojunction photocatalyst for methylene blue degradation under visible light

Synthesis of silver nanoparticles from oleander using a green method, and their application in enhancing photocatalytic degradation of MB with TiO2 &CuO Nanocomposite

“…Next, the best performing photocatalyst, TC 1 was modi ed with Ag nanoparticles as shown in Fig, 4b. Hence; Ag NPs modi cation of photocatalysts TCA 1, TCA 2 and TCA 3 endowed the TiO 2 /CuO @ Ag ternary composites the lowest re ectance the optimum composite TCA2, as a result of the synergetic effect among components [41,42]. It has been demonstrated that lowering the composite's band gap energy improves the photocatalytic reaction by allowing the produced photocatalyst to absorb more photons and become more sensitive to visible light.…”

“…It was tested against MB dye at a concentration of 20 ppm, with a catalyst dose of 0.5 g/L. The degradation percentage achieved was 83.00% [42].…”

“…Ag@CuO: This catalyst, prepared using an apolyol-mediated re uxing method, was tested against MB dye at a concentration of 20 ppm with a catalyst dose of 2 g/L. It achieved a degradation percentage of 94.43% [42].…”
