Abstract

Photocatalytic alcohol decomposition is crucial for the preparation of valuable organics, and efficient treatment of isopropyl alcohol (IPA)-contaminated water is a priority in the semiconductor industry. In this study, Fe₂O₃ nanoparticles were developed as a photoactive, environmentally friendly catalyst for the oxidation of isopropanol to acetone. The catalyst demonstrated high efficiency in an oxidative process utilizing O₂ as the sole oxidant, without the need for additional surfactants or nitrogenous bases. The novelty of the process lies in the combination of sonolysis and photocatalysis, which enhances mass transfer and accelerates acetone production. Characterization of the Fe₂O₃ nanoparticles was conducted using X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Dynamic Light Scattering (DLS), Transmission Electron Microscopy (TEM), and Scanning Electron Microscopy (SEM). This approach provides a promising strategy for the rapid mineralization of isopropanol, offering potential applications in the semiconductor industry by reducing both processing time and costs.

Fe₂O₃纳米颗粒超声辅助光催化氧化异丙醇

光催化酒精分解对于制备有价值的有机物至关重要，有效处理异丙醇（IPA）污染的水是半导体工业的优先事项。在这项研究中，Fe2O3纳米颗粒被开发成一种光活性的、环境友好的催化剂，用于异丙醇氧化成丙酮。该催化剂在使用O2作为唯一氧化剂的氧化过程中表现出高效率，不需要额外的表面活性剂或含氮碱。该工艺的新颖之处在于声波分解和光催化相结合，增强了传质，加速了丙酮的生产。利用x射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、动态光散射（DLS）、透射电子显微镜（TEM）和扫描电子显微镜（SEM）对Fe2O3纳米颗粒进行了表征。这种方法为异丙醇的快速矿化提供了一种有前途的策略，通过减少处理时间和成本，在半导体工业中提供了潜在的应用。
