“…The most widely used photocatalyst is TiO 2 . In order to allow it to absorb visible light, a large number of modification studies have been carried out, including ion doping, noble metal deposition, dye sensitization, and coupling with other substances. − Simultaneously, many researchers are dedicated to the development of non-TiO 2 photocatalysts, including complex metal oxides, sulfides, nitrides, and nitrogen oxides. − PC has recently emerged as a “green” water disinfection technology with several advantages. ,− One of the advantages is that it can directly use sunlight to achieve various chemical reactions, which can show a more excellent bacterial inactivation effect than sunlight disinfection . In addition, UV-driven PCs show better disinfection performance than UV alone .…”

The emergence of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment has created obstacles when treating infectious diseases with antibiotics. Wastewater treatment plants (WWTPs) serve as reservoirs for ARB and ARGs and can disseminate them into the environment. It is important to understand and address these risks. Generally, professional disinfection processes have been used in WWTPs to disinfect the target water body, with the goal of eliminating pathogenic microorganisms in the water. However, ARGs are not generally considered, and antibiotic resistance has spread and developed through horizontal gene transfer (HGT). This Review provides a detailed overview of the application progress of different traditional and new disinfection technologies in removing ARB and ARGs, mainly focusing on the bacterial inactivation mechanisms of chlorination, ozonation, ultraviolet (UV) (including UVA, UVB, and UVC), sunlight, sunlight-dissolved organic matter (DOM), and photocatalysis (PC)/photoelectrocatalysis (PEC). In addition, this Review also focuses on the disinfection technology involved in the transfer of ARGs and clarifies the underlying transfer mechanisms in water environments. Furthermore, by linking the mechanisms of bacterial inactivation, the Review describes how SOS response and cell membrane permeability may be the key step in the conjugation, transformation, and transduction of ARGs. Finally, given the applications and current problems associated with traditional water disinfection technologies and light-based disinfection technologies in removing and controlling ARB and ARGs, this Review describes the current challenges and opportunities to facilitate the development of future disinfection technologies. The Review also highlights future research directions related to ARG transmission control.

“…Many researchers have conducted studies on compounding different noble metals, such as Au, Ag, Pt, Pb and semiconductor materials. [33][34][35] Generally, one photoactive material can only produce a single photoelectric signal, and dual photoelectric signal sensors have recently attracted the research interest of scientists. The two materials produce anodic and cathodic photocurrent signals when Li 36 applied various bias voltages to two neighboring sections of electrodes coated dropwise with ZnIn 2 S 4 and poly (neutral red), respectively.…”

Many charged organic molecules behave as persistent and hazardous pollutants with harmful effects on human health and ecosystems. They are widely distributed related to their charged molecular structure that provides water solubility. In order to track the fate and behavior of such pollutants, charged dyes with specific absorption in the visible spectra serve as convenient model compounds. We provide a platform of smart adsorbers that efficiently remediate positively and negatively charged dyes (crystal violet and Amaranth) from water. Metal oxide nanoparticles serve as a core with an intrinsically large surface area. The surface potential was tuned towards positive or negative by decorating the cores with self‐assembled monolayers of dedicated long‐chained phosphonic acid derivatives. Selective remediation of the dyes was obtained with corresponding oppositely charged core‐shell nanoparticles. Mixed dye solution can be cleaned by a cascade approach or by applying both particle systems simultaneously. The removal efficiency was determined as a function of particle concentration via UV‐spectroscopy. The results of remediation experiments at different pH values and using superparamagnetic iron oxide nanoparticle cores lead to a simple process with recycling capability.
