Crystal violet (CV), a cationic dye, has been demonstrated to be a powerful carcinogen, a mitotic toxin and poisonous to mammalian cells such that the predominant presence of the dye invariably causes several effects of destruction to mankind and it necessitates a clarion call to do away with this nuisance before it can produce a snowball effect. The recent widespread reporting of the photocatalysis-mediated degradation of CV as an emerging technique for removing this dangerous dye from aqueous mediums highlights its effectiveness. Numerous researchers have contributed substantially to describing how photocatalysis-based nanomaterials could be used to degrade CV. The fundamentals and the factors that predominantly influence CV degradation are highlighted in this work. These factors include the nature of nanomaterials, catalyst concentration, dye dosage, pH of the solution in use, temperature and light intensity. Additionally, thorough kinetics and mechanistic descriptions are also included to give crucial insights into the light-mediated reaction of CV. The present study's findings have the potential to alleviate practitioners and researchers of the burden of having to navigate through numerous studies under each category of parameters to get an exhaustive overview of all of the different variables that may affect the photocatalytic degradation of CV dye. In order to further enhance the photocatalytic degradation efficiency of CV, researchers can expand on this study by investigating novel strategies to lessen the impact of certain elements that adversely affect the photocatalytic reaction process. The potential prospects for extending the advancement of scientific study in this area are also explored. © 2024 Society of Chemical Industry (SCI).

影响采用不同纳米结构材料的阳离子结晶紫染料光催化降解的重要因素概述

结晶紫 (CV) 是一种阳离子染料,已被证明是一种强致癌物、一种有丝分裂毒素,对哺乳动物细胞有毒,因此该染料的大量存在必然会对人类造成多种破坏作用,因此有必要大声疾呼在它产生滚雪球效应之前将其消除。最近广泛报道了光催化介导的 CV 降解作为一种从水介质中去除这种危险染料的新兴技术,突显了其有效性。许多研究人员为描述如何使用基于光催化的纳米材料来降解 CV 做出了重大贡献。这项工作强调了主要影响 CV 退化的基本原理和因素。这些因素包括纳米材料的性质、催化剂浓度、染料用量、使用溶液的pH值、温度和光强度。此外,还包括全面的动力学和机制描述,以提供对 CV 光介导反应的重要见解。本研究的结果有可能减轻从业者和研究人员的负担,他们必须浏览每一类参数下的大量研究,以获得可能影响 CV 染料光催化降解的所有不同变量的详尽概述。为了进一步提高 CV 的光催化降解效率,研究人员可以通过研究新策略来扩展这项研究,以减少某些对光催化反应过程产生不利影响的元素的影响。还探讨了扩大该领域科学研究进展的潜在前景。 © 2024 化学工业协会 (SCI)。
