Title : The use of environmental catalysis for wastewater treatment: Advancement and future perspectives
Abstract:
Environmental catalysis refers to green catalysis applied for pollutant breakdown or production of chemicals without producing an undesirable byproduct. For example, a catalyst which is derived from waste or less expensive materials is promising for circular economy. Here we review environmental photocatalysis, biocatalysis, and electrocatalysis, with a focus on catalyst synthesis, structure, and applications. The removal of toxic chemicals from the wastewater to keep a cleaner and greener environment is a challenging area nowadays for managing liquid waste. Therefore, scientists are in search of novel technologies to treat and recycle wastewater, and nanotechnology. Rapid industrialization and urbanization put significant quantities of hazardous pollutants in the marine environment, creating serious risks to human health and ecosystem. Conventional wastewater treatment methods have limited removal of stubborn organic contaminants, heavy metals, and emerging pollutants. Environmental catalysis has arisen as a gifted approach for addressing these challenges through the expansion of well-organized technologies.
Recently, in nano catalyst design have meaningfully improved the efficiency and removal of pollutants from wastewater. Nanostructured materials, including metal oxides, semiconductor nanoparticles, carbon-based nanomaterials, and hybrid nanocomposites, exhibit high surface area, improved catalytic activity, and superior selectivity compared to conventional catalysts, and catalytic reduction reactions for the treatment of industrial effluents. In current years, many researches have been working on the treatment using photo catalysts [2]. Environmental catalysis has emerged as a key approach for sustainable pollution control and green chemical processes, as discussed in recent studies.
This study reviews recent developments in nano catalysts useful for environmental remedies, with a specific focus on photocatalytic scarcity of organic pollutants and wastewater treatment policies. The instruments governing catalytic activity are discussed. Furthermore, opportunities for integrating nano catalytic technologies into large-scale wastewater treatment systems are highlighted.
The results show that environmental catalysis gives substantial efficient pollutant removal in water treatments. Carry on research in catalyst design, optimizing, and industrial employment is expected to go faster the adoption of environmentally friendly catalytic technologies for future wastewater treatment applications.
