Abstract

The presence of volatile organic sulfur compounds (VOSCs) poses serious hazards to both the environment and human health, highlighting the importance and urgency of developing efficient abatement technologies. Effective desulfurization catalysts should demonstrate sufficient catalytic activity at low temperatures, high selectivity, and robust resistance to carbon and sulfur. Achieving these attributes needs careful optimization of three key factors of the catalysts: acidity, redox properties, and active oxygen species. In this review, we explore the design and optimization of multiple catalysts by focusing on the three key factors mentioned. We also discuss the synergistic degradation of multicomponent VOSCs, along with the mechanism of catalytic reaction, catalyst deactivation, and regeneration. It is noteworthy that an innovative catalysis at room temperature is highlighted, which combines chemical and biological methods to enhance the desulfurization performance through the integration of enzymes and inorganic components. The catalytic reaction mechanism and the catalyst design by coupling the biological enzymes and inorganic substances to achieve room catalysis is systemically elaborated. It is hopeful that this review will inspire researchers in academia and industry and promote their collaborations to address future environmental desulfurization challenges by combining chemical and biological approaches.

vocs脱硫研究进展：多种催化剂和偶联酶

挥发性有机硫化合物（vocs）的存在对环境和人类健康构成严重危害，突出了开发有效减排技术的重要性和紧迫性。有效的脱硫催化剂应在低温下具有足够的催化活性、高选择性和对碳和硫的抗性。实现这些特性需要仔细优化催化剂的三个关键因素：酸度、氧化还原性能和活性氧。在本文中，我们将围绕上述三个关键因素探讨多种催化剂的设计和优化。我们还讨论了多组分vocs的协同降解，以及催化反应、催化剂失活和再生的机理。值得注意的是，重点介绍了一种创新的室温催化方法，该方法将化学和生物方法相结合，通过酶和无机组分的整合来提高脱硫性能。系统阐述了生物酶与无机物耦合实现室内催化的催化反应机理和催化剂设计。希望这篇综述能够启发学术界和工业界的研究人员，并促进他们的合作，通过化学和生物方法的结合来解决未来环境脱硫的挑战。
