Synthesis of highly efficient g-CN@CuO nanocomposite for photocatalytic degradation of phenol under visible light

Photocatalytic Degradation of Toxic Phenolic Compound and Bacterial Inactivation by Ternary Li doped Zn0.5Ni0.5Fe2O4

“…The advanced oxidation process (AOP), which uses highly oxidizing reactive oxygen species (ROS) to degrade persistent organic pollutants adsorbed on the photocatalyst surface, is one of the most favourable and versatile water technologies. [14][15][16] Four fundamental concepts govern heterogeneous photocatalysis: (a) photochemistry, (b) heterogeneous catalysis, (c) sub-atomic spectroscopy of adsorbed particles, and (d) semiconductor materials science. The absorption of photons by the semiconductor/catalytic material induces electron-hole separation, which migrates to the material sur-face and is a precursor to the creation of reactive oxygen species (ROS).…”

“…Single metal semiconductors such as ZnO, WO 3 , TiO 2 , g ‐CN@CuO, SiO 2 , and ZrO 2 −GO are some of the most commonly utilized heterogeneous catalysts for phenol‐containing wastewater treatment [1,2,16,17] . The usage of single‐metal semiconductors has been stated to have varying degrees of success by the authors.…”

“…[14] Single metal semiconductors such as ZnO, WO 3 , TiO 2 , g-CN@CuO, SiO 2 , and ZrO 2 À GO are some of the most commonly utilized heterogeneous catalysts for phenol-containing wastewater treatment. [1,2,16,17] The usage of single-metal semiconductors has been stated to have varying degrees of success by the authors. However, there are disadvantages, such as the difficulty in separating them from the reaction system after use; the wide bandgap and high recombination rate limit their photoresponses in the UV region (4-5 % of the solar spectrum) and minimize photocatalytic reactions.…”
