Emission of volatile organic compounds (VOCs) has resulted in various environmental issues. Therefore, development of effective VOC removal technology is essential for reducing the adverse effects associated. This work provides a systematic review on VOC removal from gas stream via catalytic oxidation, plasma degradation, and plasma catalysis. For catalytic oxidation of VOCs, possible reaction mechanisms and how physicochemical properties of catalyst influences catalytic performance are presented and discussed, followed by plasma removal of VOCs, VOC degradation, and byproduct formation mechanisms. Next, interactions between plasma and catalyst are interpreted for comprehensive understanding. Last, perspectives are provided for further development of VOC removal technology.

挥发性有机化合物（VOC）的排放已导致各种环境问题。因此，开发有效的VOC去除技术对于减少相关的不良影响至关重要。这项工作提供了有关通过催化氧化，等离子体降解和等离子体催化从气流中去除VOC的系统综述。对于VOC的催化氧化，提出并讨论了可能的反应机理以及催化剂的物理化学性质如何影响催化性能，然后介绍了VOC的等离子体去除，VOC降解和副产物形成机理。接下来，解释等离子体和催化剂之间的相互作用以进行全面理解。最后，为VOC去除技术的进一步发展提供了前景。
