The residues of daily-used antibiotics are difficult to be removed and very harmful to the environment. 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. This study displays an alternative strategy of surface engineering to design novel heterostructured materials for the efficient photo-Fenton treatment of wastewater containing antibiotic residues as well as other organic pollutants.

g-C3N4 has great potential in photocatalytic inactivation of algal cells but still faces challenge due to the high recombination rate of electron-hole pairs, negative surface charge and low oxidation ability of photo-generated holes. Herein, the high temperature oxidation and protonation were used to synergistically improve the photocatalytic performance of g-C3N4 on Microcystis aeruginosa inactivation. 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. While the protonation endowed the g-C3N4 with positive surface charge which was beneficial for their adsorption on the negative charged algae cells. Therefore, it is helpful to increase the charge transfer between g-C3N4 and algae cells because of their inter-attraction. All the above factors induced to the high activity on the inactivation of Microcystis aeruginosa. This work provides a new design idea for the efficient inactivation of algal cells by carbon nitride-based photocatalysts.
