The continuous upsurge in water pollution caused by harmful organic and inorganic contaminants has led to a shortage of nontoxic, clean effective waste management. Therefore, it is crucial establish an eco-friendly approach using sustainable, biodegradable, recyclable materials treat the wastewater. In this regard, photocatalysts are highly for mitigating certain degree through energy-efficient greener approach. Among various photocatalysts, polymeric nanocomposites have attracted considerable consideration owing their several advantageous characteristics like higher surface area, extended volume ratio, advanced adsorption efficiency, application degradation contaminants. comprehensive review, we focused on recent synthetic approaches development nanocomposites. Also, these also been extensively summarized. This article further discusses process photocatalysis provide clear understanding reader.

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.

Plasmonic Nanocomposites of ZnO-Ag Produced by Laser Ablation and Their Photocatalytic Destruction of Rhodamine, Tetracycline and Phenol

Materials, Год журнала: 2024, Номер 17(2), С. 527 - 527

Опубликована: Янв. 22, 2024

Hydrosphere pollution by organic pollutants of different nature (persistent dyes, phenols, herbicides, antibiotics, etc.) is one the urgent ecological problems facing humankind these days. The task water purification from such can be effectively solved with help modern photocatalytic technologies. This article devoted to study properties composite catalysts based on ZnO modified plasmonic Ag nanoparticles. All materials were obtained laser synthesis in liquid and differed their silver content preparation conditions, as additional irradiation and/or annealing produced powders. prepared ZnO-Ag powders investigated electron microscopy, X-ray diffraction UV-Vis spectroscopy. Photocatalytic tests carried out well- known test molecules dye rhodamine B, phenol common antibiotic tetracycline) using LED light sources wavelengths 375 410 nm. introduction small concentrations (up 1%) nanoparticles shown increase efficiency photocatalyst expanding its spectral range. Both conditions material composition optimized obtain photocatalysts highest efficiency. Finally, operation mechanisms distribution are discussed.

Fossil fuels play a powerful role in the global economy and are therefore referred to as strategic raw materials. However, their massive use around world is associated with concerns about sufficiency of energy sources for future generations. Currently, fossil fuel resources heavily depleted, limited supplies. According forecasts, demand will constantly increase, so it necessary find solution that reconciles ever-increasing need protect environment. The main this problem acquire from renewable resources, especially direction obtaining alternative substitutes transportation fuels. One can replace existing hydrogen. An efficient way obtain compound through modern photocatalysts. Hence, purpose paper review recent literature on effective catalysts photocatalytic processes (e.g., glycerol conversion) enable synthesis
