Zinc Oxide Nanophotocatalysts in Textile Dye Degradation: A Mini Review

Water is the essence of the universe. In recent years, Industrialization have put adverse impacts on our environment especially aquatic ecosystem. Industrial dyes are one of the main waste pollutants [1]. Dyes contaminate water ecosystem and this effects aquatic habitat. These dyes also have severe impacts on human health. So, this is alarming to treat wastewater containing hazardous coloring agents(dyes) specially belonging to the textile industry. The textile industry is of the biggest contributors for water pollution, due to large amounts of synthetic dyes released into water bodies and enhance pollution. These dyes can cause serious health and environmental issues because they resist natural degradation. The best solution to this problem is photocatalytic degradation in which nanomaterials help to the breakdown of these dyes which are basically pollutants. Zinc oxide nanoparticles have gained a lot of attention among various photo catalysts due to their strong photocatalytic activity, cost-effectiveness and environment friendliness. This review explores how the zinc oxide nanoparticles break down the dyes, the factors that influence their efficiency, and recent developments in improving their performance. In this review we also highlight future directions, which include green synthesis methods and integration of zinc oxide with renewable energy sources for applications that are more environmentally friendly
