Herein, FeOx@FeP heterostructure was constructed by surface phosphorization of hematite (α-Fe2O3) synthesized via a facile hydrothermal method for efficient photo-Fenton degradation of antibiotic norfloxacin (NOR). Compared with the bare α-Fe2O3, the FeOx@FeP heterostructure exhibits much-enhanced photocatalytic Fenton-like performance, with NOR degraded by 75% within 5 min by sunlight-driven photo-Fenton reactions. It was suggested that the surface phosphorization-derived metallic FeP overlayer could accelerate the separation and migration of photogenerated charge carriers in α-Fe2O3, which benefits the generation of •OH and O2•− reactive radicals from photo-Fenton reaction and thus give rise to the great enhancement in NOR degradation activity.

Under visible light, inactivation percent of Microcystis aeruginosa by the best sample 15NCN reached 92.6%, much higher than that of g-C3N4 (6.8%). Results showed that high temperature oxidation induced to higher separation efficiency of photo-generated electron-hole pairs and higher oxidizing capacity of the generated holes.

Therefore, it is helpful to increase the charge transfer between g-C3N4 and algae cells because of their inter-attraction.

More recently, SACs have become ideal catalyst materials and have been extensively applied in water treatment. This review summarizes the classification of advanced oxidation processes (AOPs, e.g., photocatalysis, electrocatalysis, Fenton-like reactions, persulfate oxidation and multi-technology coupling reaction) for the degradation of organic pollutants in water on SACs. The corresponding mechanisms for the removal of organic pollutants over SACs in the above technologies are also discussed. Distinguished from traditional nanoparticles and nanoclusters, the unique electronic properties of single metal atoms and the formation of covalent bands between metallic and nonmetallic atom promote the rapid generation of reactive oxygen species (SO4•-, O2•-, •OH and 1O2), which endow SACs with excellent removal efficiency of organic pollutants.
