Abstract
The synthesis and characterization of novel p-type copper delafossite CuBO2 microstructures were performed using an eco-friendly and cost-effective hydrothermal process. This study aims to explore the potential of these microstructures for environmental applications, specifically in the photo-induced degradation of hazardous dyes in wastewater. Various growth times were investigated to determine their influence on the morphology and photocatalytic performance of the synthesized microstructures. The characterization was carried out using X-ray diffractometer (XRD), field emission scanning electron microscope (FESEM), and transmission electron microscope (TEM). The energy dispersive X-ray (EDX) studies and UV-Vis spectrophotometer were used to analyze the optical properties and compositional purity. The synthesized CuBO2 microstructures demonstrated significant photocatalytic activity, with the optimal sample synthesized in 2 h exhibiting a high degradation rate constant of 0.263 min−1, it was found that the materials synthesized for the ideal 2 h exhibited good photocatalytic activity. The results indicated that the photocatalytic activity of the CuBO₂ samples improved with increasing growth time, attributed to the enhanced crystallinity and larger surface area of the microstructures. Moreover, The findings suggest that these hierarchical microstructures have a strong potential for use in wastewater treatment applications. This work indicates that CuBO2 can be a versatile and effective material for environmental remediation, highlighting its importance in developing sustainable solutions for pollution control.
本研究采用环保且经济高效的水热法合成了新型 p 型铜 delafossite CuBO2 微结构，并对其进行了表征。本研究旨在探索这些微结构在环境应用方面的潜力，特别是在光诱导降解废水中的有害染料方面。研究了不同的生长时间，以确定它们对合成微结构的形态和光催化性能的影响。表征采用了 X 射线衍射仪（XRD）、场发射扫描电子显微镜（FESEM）和透射电子显微镜（TEM）。能量色散 X 射线（EDX）研究和紫外可见分光光度计用于分析光学特性和成分纯度。合成的 CuBO2 微结构表现出显著的光催化活性，2 h 内合成的最佳样品表现出 0.263 min-1 的高降解速率常数，发现理想的 2 h 内合成的材料表现出良好的光催化活性。结果表明，CuBO₂样品的光催化活性随着生长时间的延长而提高，这归因于微结构的结晶度提高和比表面积增大。此外，研究结果表明，这些分层微结构在废水处理应用中具有很大的潜力。这项研究表明，CuBO2 是一种多功能、有效的环境修复材料，在开发可持续的污染控制解决方案方面具有重要意义。
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.
