“…Cocatalysts are considered to be an effective strategy to reduce the overpotential and activation energy of hydrogen reduction, expose more active sites, accelerate the separation/migration of photogenerated electron/hole pairs, and ultimately improve the photocatalytic activity. Until now, many researchers have developed various cocatalytic materials, such as noble metals, alloys, , sulfides, , and other cocatalysts . Zhu and co-workers loaded Au onto ZIS by an in situ photodeposition method and found that 0.5% Au/ZIS had the highest photocatalytic activity, which was 4.4 times higher than that of pure ZIS .…”

Photocatalytic technology still faces enormous challenges to design and synthesize highly efficient photocatalytic materials with a high electron/hole separation efficiency, rapid charge migration, low carrier recombination rate, and strong visible light-harvesting capability. Herein, Cu-doped ZnIn2S4/Ni x P (marked Cu y ZIS/NP) composites were successfully synthesized by a simple two-step method. The synergistic effect of Cu2+ doping and the Ni x P cocatalyst on hydrogen evolution performance was investigated in detail. The results showed that superior photoactivity over Cu y ZIS/NP composites was achieved. The optimal Cu0.5ZIS/NP-1/2 sample had a hydrogen evolution rate of 4746.3 μmol·g–1·h–1 under visible light irradiation, which was approximately 15.98 times higher than that of pure ZnIn2S4 (297 μmol·g–1·h–1). This work may offer a valuable insight into understanding the synergistic effect of doping and cocatalysis and provide a guideline for designing and developing highly efficient visible light-driven photocatalysts toward a water splitting system.

“…However, DCF waste is poorly treated and reaches water treatment plants, resulting in the residue of DCF in surface and groundwater. In addition, DCF at low concentration can cause cytological changes in animals in aquatic environment (Li et al, 2021, Acuña et al, 2015, which can cause a risk to aquatic ecosystems. Thus, DCF exposed to the natural environment needs to be removed urgently.…”

“…Sodium diclofenac sodium, a non-steroidal drug, acts in the body by decreasing the production of prostaglandins, which play an important role in causing inflammation, pain, and fever. The unbridled consumption of this drug linked to a wide diversity of applications, which does not restrict its purchase in drugstores, consequently contributes to the contamination of effluents when it comes to the issue of disposal and waste production (Li et al, 2021;Lima et al, 2015;Santos & Bergold, 2007).…”

“…These technologies submerge reactive oxygen species (ROS), which makes possible the degradation of organic pollutants with various chemical structures and functional groups to fewer toxic substances. The correct management, recycling and treatment of these wastes should be performed, in order to ensure that the emission of substances of high concern and contamination is avoided, ensuring environmental protection of human health (Hahladakis et al, 2018;Li et al, 2021;Hu, Zhai and Zhu, 2021).…”

Worldwide, there is an increasing incidence of contaminants in aqueous matrices, among them, antibiotics, pesticides and pharmaceutical products. This problem, coupled with the occurrence of these pollutants at trace levels, creates unique challenges for the analytical detection and performance evaluation of the removal of these contaminants from water. The purpose of this experiment was to optimize the operational conditions of the Photo-fentom like process of sodium diclofenac residues by Response Surface Methodology (RSM), based on analysis in aqueous solution. The drug was determined via UV-Vis spectrophotometry using a 23 factorial design with a central point to evaluate the degradation of the sodium diclofenac. The design was composed of two levels and three factors: (X1) Irradiation time, ranging from 2 to 4 h; (X2) Hydrogen peroxide content, ranging from 1 to 7%; and (X3) Fe2+ concentration, ranging from 25 to 100 mg L-1. According to the levels defined for each parameter, the optimized methodology showed that the best degradation of the drug was achieved by combining 2 h of irradiation, 1% Hydrogen peroxide solution and 25 mg L-1 of solution containing Fe2+, where 97.04% of drug degradation was achieved. From ANOVA it could be inferred that the concentration of Fe2+ (p = 0.13044) and the interaction irradiation time with Fe2+ concentration (X1X3) (p = 0.0439) had the highest significance in the degradation process. The experimental planning was useful to indicate the region of maximum degradation, therefore, the methodology was suitable for degradation of residues of this drug in water samples.
