A 1D/2D BiO/g-CN step-scheme photocatalyst to activate peroxymonosulfate for the removal of tetracycline hydrochloride: insight into the mechanism, reactive sites, degradation pathway and ecotoxicity.

A novel 1D/2D step-scheme BiO/g-CN was prepared using a simple reflux method. BiO photocatalysts showed lower photocatalytic activity for the degradation of tetracycline hydrochloride under visible light irradiation. After compositing with g-CN, the photocatalytic activity of BiO was enhanced obviously.

Synthesis of a ternary BiO/CQDs/rGO photocatalyst to active peroxymonosulfate for the removal of tetracycline hydrochloride.

In this paper, the ternary BiO/CQDs/rGO photocatalyst was synthesized by a solvothermal method. The as-fabricated BiO/CQDs/rGO composites showed stronger visible-light response and higher photocatalytic activity. In order to further enhance the degradation efficiency of tetracycline hydrochloride, BiO/CQDs/rGO was used to activate peroxymonosulfate under visible-light irradiation.

Efficient degradation of VOCs using semi-coke activated carbon loaded ternary Z-scheme heterojunction photocatalyst BiVO-BiPO-g-CN under visible light irradiation.

The coal chemical industry generates large amounts of solid waste and volatile organic compounds (VOCs). In this study, the solid waste semi-coke powder obtained in the semi-coke production process was used as a raw material to prepare high-specific surface area semi-coke activated carbon (SAC) by a carbonization and activation process, and a ternary z-scheme heterojunction photocatalyst with high catalytic performance was loaded for synergistic treatment by adsorption and photodegradation to achieve waste treatment with waste. The prepared semi-coke activated carbon has a specific surface area of 619.

Synergetic effect of photocatalysis and peroxymonosulfate activated by MFeO (M = Co, Mn, or Zn) for enhanced photocatalytic activity under visible light irradiation.

Nanosized MFeO (M = Co, Mn, or Zn) photocatalysts were synthesized a simple sol-gel method. MFeO photocatalysts exhibited lower photocatalytic activity for the degradation of levofloxacin hydrochloride under visible light irradiation. For enhancement of photocatalytic activity, MFeO was used to activate peroxymonosulfate and degrade levofloxacin hydrochloride under visible light irradiation.
