Summary: Ti3+/Ti4+ co-doped FeOCl was prepared by a simple calcination process, which exhibited 7 times higher photo-Fenton catalytic activity compared to FeOCl. The doping of Ti3+/Ti4+ in FeOCl resulted in a significant increase in the surface area by 16.4 times. The fast reduction of Fe3+ by photogenerated electrons and the presence of Ti3+ promoted the decomposition of H2O2 to generate hydroxyl radicals. These findings provide insights for the design and synthesis of novel structured photo-Fenton catalyst.

Summary: Carbamazepine (CBZ) is a contaminant of emerging concern in water environments. Various photo-Fenton reactions using FeOCl as catalyst were evaluated for enhanced CBZ removal, achieving a high removal rate of 92% under UV/H2O2/FeOCl system. The study also analyzed the effects of common anions on CBZ degradation and identified three possible degradation pathways and byproducts.

Summary: This study investigates the adsorption and Fenton activity of FeOCl using rhodamine B and bromocresol green as pollutant models at different pH values. The results show that adsorption and Fenton reactions occur simultaneously, with the extent depending on the pH and the type of pollutant. FeOCl exhibits potential as a catalyst for Fenton, photo-Fenton, and photocatalysis, but its activity is greatly influenced by humidity and the ionic charge of the contaminant.

Summary: In this study, nitrogen and sulfur co-doped nanocarbon materials (NSC) were designed and synthesized, which showed superior catalytic performance in enhancing the Fe(III)/H2O2 system for sulfamethoxazole (SMX) degradation. The introduction of NSC increased the kobs by 18 times compared to the Fe(III)/H2O2 system under the same experimental conditions. NSC also expanded the working pH range of the Fe(III)/H2O2 system. The results suggested that the presence of NSC promoted direct reduction and in-situ binding of Fe(III), contributing to the enhanced degradation of SMX.

Summary: Solar cells are a promising source of energy conversion. However, the traditional use of Pt as a counter electrode (CE) in solar cells is expensive, scarce, and corrosive. To address this issue, a novel quaternary nanocomposite of rGO/MnO2/NiO/CuO (RMNCu) was employed as the CE in DSSCs with different photoanodes. The DSSCs with RMNCu as the CE exhibited a power conversion efficiency (PCE) of 93.31% compared to Pt-CE in the same conditions, making RMNCu a promising candidate for DSSC counter electrodes.

Summary: CuFe2O4 was prepared by coprecipitation method, and 1T/2H-MoS2/CuFe2O4 composite catalyst (MC-x for short) was first prepared by hydrothermal method. The MC-200 catalyst exhibited the best performance in Phenol degradation, with a degradation rate of 95.8% within 20 min. XPS analysis confirmed that 1T MoS2 promoted the cyclic transformation of Fe3+/Fe2+ and Cu2+/Cu+ in the reaction system. Active radical trapping experiment and ESR showed that SO4•- was the main active substance in MC-200/PMS system. This study provides a new insight into the application of MoS2/spinel ferrite/PMS in wastewater treatment.
