In recent times, leakage of the organic pollutants into water reserves because of the uncontrolled and ill-planned industrial development was regarded as one of the most fundamental worldwide concerns. The hazardous and deleterious effects associated with these pollutants demand the invention of effective degradation methodologies, which could be industrially employed prior to the discharge of industrial effluent into the aqueous environment. Various removal methods have been explored from the perspective of addressing this issue. The nanoparticles-(NPs) mediated photocatalytic degradation is one of such approaches which has attracted attention. Recently, the use of Zinc oxide (ZnO) NPs as heterogeneous photocatalysts has been under much review due to the improvements that have been presented for enhancing its catalytic efficacy and inhibiting photo-corrosion problems. Hence, a critical analysis summarizing and discussing these recent advances on ZnO NPs modification is needed. In this study, the descriptions of (1) stabilization mediums for NPs into producing more suitable and appropriate supports, (2) the revision of the architecting routes for ZnO NPs, (3) the introduction of various sorts of metal doping for enhancing the electron transduction capabilities of ZnO NPs and (4) the development of bi/polymetallic assemblies for combining the most-suited features of different metals in a single catalytic system are discussed. This article presents a comprehensive overview of the latest modifications achieved for the nanoassemblies of ZnO NPs employed for the light-mediated decomposition of organic pollutants.

氧化锌基光催化组件设计方案的最新进展

近年来,由于工业发展不受控制和计划不周而导致有机污染物渗入水储备被视为世界上最基本的问题之一。与这些污染物相关的有害和有害作用要求发明有效的降解方法,该方法可以在将工业废水排放到水性环境中之前在工业上使用。从解决该问题的角度出发,已经探索了各种清除方法。纳米颗粒-(NPs)介导的光催化降解是引起关注的此类方法之一。最近,氧化锌(ZnO)NPs作为非均相光催化剂的使用受到了广泛的审查,这是由于已经提出了用于增强其催化效力和抑制光腐蚀问题的改进方法。因此,需要进行总结和讨论这些有关ZnO NPs修饰的最新进展的关键分析。在这项研究中,描述了(1)NP的稳定介质以产生更合适和合适的载体,(2)ZnO NP的构造途径的修订,(3)引入各种金属掺杂以增强电子讨论了ZnO NPs的转导能力,以及(4)在单个催化系统中结合不同金属的最适合特征的双/多金属组件的开发。
