Abstract Human existence and societal growth are both dependent on the availability of clean fresh water. Photocatalysis is a type artificial photosynthesis that uses environmentally friendly, long-lasting materials to address energy environmental issues. There currently considerable demand for low-cost, high-performance wastewater treatment equipment. By changing structure, size, characteristics nanomaterials, use nanotechnology in field water filtration has evolved dramatically. Semiconductor-assisted photocatalysis recently advanced become among most promising techniques fields sustainable generation ecological cleanup. It beneficial, cost-effective, strictly linked zero waste discharge principle used industrial effluent treatment. Owing reduction or removal created unwanted byproducts, green synthesis photoactive nanomaterial more beneficial than chemical approaches. Furthermore, unlike methods, method does not require expensive, dangerous, poisonous ingredients, making it less costly, easy, photocatalyst synthesis. This work focuses distinct greener utilized production new photocatalysts, including metals, metal doped-metal oxides, plasmonic nanostructures, application intelligence machine learning design selection an innovative context challenges. A brief overview applications photocatalysts also presented. Finally, recommendations future research given create photocatalytic systems with greatly improved stability efficiency.

The emerging field of using titanium dioxide (TiO 2 )-based photosensitizers for enhancing photocatalytic removal thiazine dyes such as methylene blue (MB) from water has long been recognized its exceptional properties, making it an attractive material environmental remediation and energy conversion. However, wide bandgap limits responsiveness to visible light. As such, the utilization TiO -based dyes, presents a promising avenue diverse applications. In addressing dual challenges pollution harnessing sustainable sources, this review focuses on their subsequent application materials. Thiazine ubiquitous in industrial effluents, pose concerns due persistence potential toxicity. Conversely, innovative approach involves employing materials photocatalysts, utilizing unique properties enhance light absorption. Studies have shown that beyond conventional role colorants, they can serve effective when coupled with . This tandem not only facilitates elimination MB, but also augments improvement performance synergy between dye sensitizers enhances overall efficiency processes like degradation splitting. Dye sensitizers, acting absorbers, efficiently transfer , thereby promoting electron generating reactive oxygen species (ROS). These ROS, turn, initiate chemical reactions, rendering valuable applications wastewater treatment, solar conversion, remediation. is crucial acknowledge drawbacks associated including toxicity non-biodegradability. Consequently, careful consideration must be given disposal. Therefore, manuscript delves into comprehensive exploration photosensitizers, shedding efficacy various removal.

It is a challenging task to design piezoelectric photocatalyst with excellent performance under mechanical agitation instead of ultrasonic irradiation. Integrating vacancy defects into heterojunction seems be an effective strategy for synergistically increasing its piezo-photocatalytic performance. For this goal, two-step hydrothermal method was adopted architect type-I oxygen-vacancy-rich BaTiO3/BiOBr surge the degradation Rhodamine B (RhB) combined action simulated sunlight irradiation and agitation. Various instrumental techniques demonstrated formation high crystallinity. The existence surface oxygen vacancies confirmed by XPS EPR tests. PFM results manifested that had properties, response value 30.31 pm V–1. Comparative experiments indicated RhB efficiency piezo-photocatalysis over largely exceeded total sum those piezocatalysis photocatalysis. h+, ·O2–, 1O2 were dominant reactive species degradation. improved separation photogenerated charges verified electrochemical measurements. DFT calculations polarization BaTiO3 could affect electronic band structure BiOBr. This work will provide comprehensive insights mechanism at microcosmic level help develop new-styled photocatalysts.

The incidence of water pollution in developing countries is high due to the lack regulatory policies and laws that protect bodies from anthropogenic activities industrial wastewater. Industrial wastewater contains significant amounts heavy metals are detrimental human health, aquatic organisms, ecosystem. focus this review was evaluate sources treatment methods wastewater, with an emphasis on technologies, advantages, disadvantages, innovation. It observed conventional (such as flotation, coagulation/flocculation, adsorption) had shown promising results but posed certain limitations, such generation volumes sludge, relatively low removal rates, inefficiency treating metal concentrations, sensitivity varying pH. Recent technologies like nanotechnology, photocatalysis, electrochemical coagulation have advantages over for removing metals, including higher improved energy efficiency, greater selectivity specific contaminants. However, costs associated these advanced remain a major drawback. Therefore, we recommend future developments technology reducing both waste generation.
