Abstract

Volatile organic compounds (VOCs) are critical gaseous air pollutants attracting increasing attention. Isopropanol, recognized as a hazardous pollutant, has been studied for its potential use in removing this contaminant through various methods. Among these approaches, catalytic oxidation stands out as an effective technique that avoids secondary contamination from isopropanol degradation products. This review discusses isopropanol catalytic oxidation, considering the medium, catalysts, and factors influencing the various processes. The benefits of precipitation, oxygen addition, and water usage are notably highlighted. Furthermore, the progress and performance of several families of catalysts, particularly noble and transition metals, are presented individually. Finally, the catalytic oxidation of isopropanol in a mixture with other VOCs is also examined. The primary aim of this review is to investigate the isopropanol catalytic oxidation process using novel composites and evaluate their effectiveness.

异丙醇的催化氧化：综述

挥发性有机化合物（VOCs）是一种重要的气态大气污染物，越来越受到人们的关注。异丙醇是一种公认的有害污染物，人们研究了异丙醇通过各种方法去除该污染物的潜在用途。在这些方法中，催化氧化是避免异丙醇降解产物二次污染的有效技术。本文综述了异丙醇的催化氧化反应，包括介质、催化剂和影响各反应过程的因素。特别强调了降水、加氧和用水的好处。此外，还分别介绍了几种催化剂的进展和性能，特别是贵金属和过渡金属。最后，还研究了异丙醇在与其他挥发性有机化合物混合物中的催化氧化作用。本综述的主要目的是研究新型复合材料在异丙醇催化氧化过程中的应用，并评价其有效性。

期刊介绍： The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water, aqueous solutions and other hydrogen-bonded liquids – Lubricants, polymer solutions and melts – Molten metals and salts – Phase transitions and critical phenomena in liquids and confined fluids – Self assembly in complex liquids.– Biomolecules in solution The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include: – Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.) – Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.) – Light scattering (Rayleigh, Brillouin, PCS, etc.) – Dielectric relaxation – X-ray and neutron scattering and diffraction. Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
