The rapidly expanding industrialization and global increase in economic activities have drawn attention to the concerning accumulation of waste. The textile industry plays a significant role in environmental pollution, especially in and water pollution. Harmful dyes used during the fabrication process are mixed with water bodies through sewage or wastewater ejected from industrial factories. These toxic dyes are not only applied in textile industries but also used in other industries like pharmaceutical companies and rubber manufacturing. Therefore, scientists have adopted alternative techniques for the degradation of organic dyes because of eliminating the drawbacks from the traditionally used techniques. Catalytic degradation of organic dyes with the help of a safe and easy nanocatalyst is one of the best alternatives. Accordingly, the use of biomaterials or waste materials offers an easy, cost-effective and eco-friendly approach for the synthesis of such nanocatalysts. Several nanocatalysts have been used for the degradation of dyes present in industrial wastewater. The well-known semi-conductor selenium has several important properties, , optoelectronic, photovoltaic, thermoconductivity, and anisotropy, and has drawn significant research attention for its catalytic application in dye degradation. Considering all these points, selenium nanoparticles synthesized green techniques provide the best possible alternative catalyst for the degradation of organic dyes in industrial wastewater. The current review covers various aspects of the biosynthesis of selenium nanoparticles; their application as a catalyst for the degradation of harmful organic dyes, , methylene blue, methyl orange, rhodamine B, alizarin S, malachite green, sunset yellow, fuchsin, safranin T, Congo red, and bromothymol blue; and their mechanism for the degradation process. This review will also shed light on the importance of using green chemistry towards the synthesis of selenium nanoparticles and different biosynthesis procedures and explores all aspects of the interesting catalytic activity towards the dye degradation mechanism. Hence this article will be beneficial to both industrialists and acdemicians bridging the gap between industrial and academic sceintists.
迅速扩张的工业化进程以及全球经济活动的增加，已使人们开始关注令人担忧的废物积累问题。纺织工业在环境污染中扮演着重要角色，尤其是在水污染方面。制造过程中使用的有害染料通过工业工厂排放的污水或废水混入水体。这些有毒染料不仅应用于纺织工业，还用于制药公司和橡胶制造等其他行业。因此，由于传统技术存在缺陷，科学家们采用了替代技术来降解有机染料。借助安全简便的纳米催化剂催化降解有机染料是最佳替代方案之一。相应地，使用生物材料或废料为合成此类纳米催化剂提供了一种简便、经济高效且环保的方法。几种纳米催化剂已被用于降解工业废水中的染料。著名的半导体硒具有多种重要特性，如光电、光伏、热导率和各向异性，并且因其在染料降解中的催化应用而备受研究关注。考虑到所有这些因素，采用绿色技术合成的硒纳米颗粒为工业废水中有机染料的降解提供了最佳的替代催化剂。本综述涵盖了硒纳米颗粒生物合成的各个方面；它们作为催化剂用于降解有害有机染料（如亚甲基蓝、甲基橙、罗丹明B、茜素S、孔雀石绿、日落黄、品红、番红T、刚果红和溴百里酚蓝）的应用；以及它们的降解过程机制。本综述还将阐明绿色化学在硒纳米颗粒合成中的重要性以及不同的生物合成程序，并探讨其对染料降解机制有趣催化活性的各个方面。因此，本文将对弥合工业科学家和学术科学家之间差距的实业家和学者都有益。
