Abstract

The present study reports a rapid and simple one-pot modified sol–gel process to prepare a hybrid Cu-doped Au@ZnO nanocomposite. Dimethyl sulfoxide (DMSO) was used as a solvent which plays a crucial role in elaborating this hybrid nanocomposite without any surfactant or ligand. Characterization techniques, including XRD, TEM, and UV–Visible highlighted the critical role of Cu in enhancing the photocatalytic activity of the sample. On the other hand, experimental studies on the structural, microstructural, and optical properties of the obtained nanomaterial have been reported. The resultant hybrid Cu-doped Au/ZnO heterostructures exhibit excellent photocatalytic activity in the photodegradation of diuron under UV light irradiation, which is much higher than Au/ZnO heterostructures. The performance of the prepared photocatalyst can be also attributed to the simple experimental protocol which generated highly pure nanoparticles with controllable size and shape. We expected that this method could be developed to prepare more semiconductor nanomaterials for different applications.

快速、简单的一锅修饰溶胶-凝胶法制备cu掺杂和au修饰ZnO纳米粒子：微观结构和光催化性能

本研究报道了一种快速、简单的单锅修饰溶胶-凝胶法制备掺杂cu的Au@ZnO纳米复合材料。二甲基亚砜（DMSO）作为溶剂，在制备这种不含任何表面活性剂和配体的杂化纳米复合材料中起着至关重要的作用。表征技术，包括XRD， TEM和UV-Visible都强调了Cu在提高样品光催化活性方面的关键作用。另一方面，对所获得的纳米材料的结构、微观结构和光学性质进行了实验研究。在所制备的杂化cu掺杂Au/ZnO异质结构中，在紫外光照射下表现出优异的光催化活性，远高于Au/ZnO异质结构。所制备的光催化剂的性能也可以归功于简单的实验方案，产生了高纯度的纳米颗粒，尺寸和形状可控。我们期望这种方法可以用于制备更多不同用途的半导体纳米材料。图形抽象

期刊介绍： The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
