Antibiotic overuse and indiscriminate disposal ultimately lead to overexploitation of the ecosystems expanding requirements, producing significant environmental and biological consequences. Advanced oxidation processes (AOPs) have kindled the interest of many researchers in targeting the destruction of antimicrobial and waterborne pollutants. As a result, an improvement of low-cost, high-efficiency photocatalysts for the successful decomposition of antibiotics is critical for the cleaning of harmful contaminants in rivers and lakes. In the current work, a simple hydrothermal approach was used to create the bismuth vanadate nanoballs (BiVO 4 ) anchored to the exterior of the ultrathin g-C 3 N 4 . It was named g-C 3 N 4 /BiVO 4 (X) (X = 5, 10, 15, and 20%) nanocomposites, and the photocatalytic removal of ciprofloxacin (CPX) and amoxicillin (AMX) was investigated using synthesized composites. According to the advanced characterization techniques, the synthesized composites exhibit superior purity and crystalline nature. The electron transfer occurring within the g-C 3 N 4 , in conjunction with the extension of BiVO 4 nanoballs, enhances the generation of photoexcited electron−hole (e − /h + ) pairs. This phenomenon contributes significantly to the improved photocatalytic activity observed in the g-C 3 N 4 /BiVO 4 system. Furthermore, the photocatalytic efficiency exhibited by g-C 3 N 4 /BiVO 4 (10%) nanocomposites in antibiotic removal surpasses that of both bare materials and other composite counterparts. The elimination of antibiotics was aided by reactive oxygen species (ROS) such as O 2 •− , h + , and OH. Finally, g-C 3 N 4 /BiVO 4 (10%), the intermediate byproduct of CPX and AMX decomposition, was discovered, and a probable CPX and AMX removal route was postulated. The g-C 3 N 4 /BiVO 4 (10%) composite exhibits long-term stability after five cycles. This study applies a green and ecologically responsive technique to the development of high-performance photocatalysts for wastewater remediation.

“…Other efforts to improve the morphological and textural features have been made by acting directly on inorganic active phases, as in the examples of entries 10 and 11 in Table 1, where crystalline porous solids [119] (zeolites and a metal-organic framework, MOF) have been used, taking advantage of to their large surface area, tunable porosity and chemistry [120][121][122]. In particular, in entry 11, MIL (Materials of Institute Lavoisier) indicates one of the most popular MOFs and MIL-101 (Fe) is the one assembled by 1,4benzene dicarboxylate ligand and iron(III) cation [123].…”

The use of hydrogen peroxide (produced in situ or ex situ) as the main agent in oxidative processes of environmental pollutant removal is widely studied. The degradation of water pollutants, such as dyes, pharmaceuticals, cosmetics, petroleum derivatives, and even pathogens, has been successfully obtained by different techniques. This review gives an overview of the more recent methods developed to apply oxidative processes mediated by H2O2 and other reactive oxygen species (ROS) in environmental catalysis, with particular attention to the strategies (Fenton-like and Bio-Fenton, photo- and electro-catalysis) and the materials employed. A wide discussion about the characteristics of the materials specifically studied for hydrogen peroxide activation, as well as about their chemical composition and morphology, was carried out. Moreover, recent interesting methods for the generation and use of hydrogen peroxide by enzymes were also presented and their efficiency and applicability compared with the Fenton and electro-Fenton methods discussed above. The use of Bio-Fenton and bi-enzymatic methods for the in situ generation of ROS seems to be attractive and scalable, although not yet applied in full-scale plants. A critical discussion about the feasibility, criticalities, and perspectives of all the methods considered completes this review.
