Abstract

Cooking oil fumes contain complex particulate matter and volatile organic compounds (VOCs), which pose a significant threat to the atmospheric environment and human health. This review offers a detailed analysis of the chemical compositions and emission characteristics of VOCs from cooking oil fumes and their corresponding treatment methods, with the highlight being put on the current state of catalytic VOC oxidation, which covers the oxidation of various VOCs, including alkanes, aromatics, oxygenated VOCs, and mixed VOCs. The review also explores the types and formation mechanisms of the byproducts of VOC oxidation. Moreover, it offers an in-depth examination of catalytic oxidation performance, mechanisms, and future development directions of various catalysts, including noble-metal-based, transition metal oxide, and rare-earth-doped catalysts. The conclusions drawn from this review can provide useful insights into efficient elimination of VOCs from cooking and related industries.

期刊介绍： ACS ES&T Engineering publishes impactful research and review articles across all realms of environmental technology and engineering, employing a rigorous peer-review process. As a specialized journal, it aims to provide an international platform for research and innovation, inviting contributions on materials technologies, processes, data analytics, and engineering systems that can effectively manage, protect, and remediate air, water, and soil quality, as well as treat wastes and recover resources. The journal encourages research that supports informed decision-making within complex engineered systems and is grounded in mechanistic science and analytics, describing intricate environmental engineering systems. It considers papers presenting novel advancements, spanning from laboratory discovery to field-based application. However, case or demonstration studies lacking significant scientific advancements and technological innovations are not within its scope. Contributions containing experimental and/or theoretical methods, rooted in engineering principles and integrated with knowledge from other disciplines, are welcomed.
