摘　　要：近年来,能高效净化H_(2)S并回收硫资源的选择性催化氧化技术(H_(2)S-SCO)受到了广泛关注.开发高性能、高选择性及低成本的催化剂是H_(2)S-SCO技术的研究重点,其中富氮碳基催化剂(RNCC)具有高活性、无金属、易制备、低成本且易再生等优点,被认为是一类极具潜力的H_(2)S-SCO催化剂.本文介绍了金属基催化剂的发展,总结和归纳RNCC的制备方法、催化活性和物化性质,系统地讨论RNCC的构-效关系及影响RNCC性能的关键因素,并总结了RNCC的H_(2)S-SCO反应机理.最后指出RNCC目前存在机遇和挑战,并展望了未来的发展方向.In recent years,selective catalytic oxidation(H_(2)S-SCO)technology,which can efficiently purify H_(2)S and recover sulfur resources,has received much attention.Research on the development of high-performance,high-selective,and low-cost catalysts is the focus of H_(2)S-SCO technology,among which the nitrogen-rich carbon-based catalysts(RNCCs),which have the advantages of high activity,metal-free,easy-to-prepare,low cost,and easy to be regenerated,are considered as a class of highly promising catalysts for H_(2)S-SCO.In this article,the development of metal-based catalysts is introduced,the preparation method,catalytic activity,and physical-chemical properties of RNCC are summarized and generalized,the structure-efficacy relationship of RNCC and the key factors affecting the performance of RNCC are systematically discussed,and the H_(2)S-SCO reaction mechanism of RNCC is concluded.Finally,the current opportunities and challenges of RNCC are also pointed out,and the future development direction is envisioned.
