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.

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.
