Abstract

ABSTRACT Nanophotocatalysts have numerous applications in the field of water splitting, dissociation of volatile organic pollutants, organic synthesis, degradation of dyes/hazardous contaminants, cancer cells inactivation, self-cleaning surfaces, hydrogen evolution, photo-electrochemical conversion, etc. Typically, to produce nanophotocatalysts, diverse conventional physicochemical strategies have been reported with some important drawbacks/limitations such as the utilization of toxic/hazardous materials, complex/expensive instruments, and time-consuming reactions. Therefore, there is a high demand for developing green, environmentally friendly, and cost-effective synthetic tactics, which can reduce or eliminate the rigorousness and complications of the conventional approaches. These nanophotocatalysts have shown high stability, good recyclability, and remarkable catalytic activity. Typically, the significant specific surface areas, the abundant functional groups, large amounts of active sites are the important advantages of the nanoscaled structures for highly photocatalytic degradation of organic pollutants. However, more elaborative studies are still needed to overcome some important limitations/drawbacks of nanophotocatalysts for industrial applications, which include the difficult separation, low selectivity, aggregation/sedimentation, low-usage of visible light, fast charge recombination, and low migration potential of photo-generated electrons and holes. This review highlights recent advances related to the greener and eco-friendly synthesis of nanophotocatalysts, as well as their environmental photocatalytic applications. Graphical Abstract

绿色环保纳米光催化剂的合成研究进展

纳米光催化剂在水分解、挥发性有机污染物解离、有机合成、染料/有害污染物降解、癌细胞灭活、表面自清洁、析氢、光电转化等领域有着广泛的应用。通常，为了生产纳米光催化剂，各种传统的物理化学策略都有一些重要的缺点/限制，如使用有毒/有害材料，复杂/昂贵的仪器，以及耗时的反应。因此，开发绿色、环保、高性价比的合成策略，以减少或消除常规方法的严谨性和复杂性是一个很高的要求。这些纳米光催化剂具有较高的稳定性、良好的可回收性和显著的催化活性。具有显著的比表面积、丰富的官能团、大量的活性位点是纳米结构光催化降解有机污染物的重要优势。然而，为了克服纳米光催化剂在工业应用中的一些重要限制/缺陷，包括难以分离、选择性低、聚集/沉降、可见光利用率低、快速电荷重组以及光生电子和空穴的低迁移潜力，还需要进行更详细的研究。本文综述了纳米光催化剂的绿色环保合成及其环境光催化应用的最新进展。图形抽象

期刊介绍： Comments on Inorganic Chemistry is intended as a vehicle for authoritatively written critical discussions of inorganic chemistry research. We publish focused articles of any length that critique or comment upon new concepts, or which introduce new interpretations or developments of long-standing concepts. “Comments” may contain critical discussions of previously published work, or original research that critiques existing concepts or introduces novel concepts. Through the medium of “comments,” the Editors encourage authors in any area of inorganic chemistry - synthesis, structure, spectroscopy, kinetics and mechanisms, theory - to write about their interests in a manner that is both personal and pedagogical. Comments is an excellent platform for younger inorganic chemists whose research is not yet widely known to describe their work, and add to the spectrum of Comments’ author profiles, which includes many well-established inorganic chemists.
