碳纳米管(CNTs)具有比表面积大、热稳定性高、电子传递性好及吸附能力强等独特的性质,近年来其作为催化剂应用于催化氧化脱氢(ODH)反应受到广泛关注。作为ODH反应的非金属催化剂,CNTs具有催化效率高、选择性好、稳定性强及污染小和可重复利用等优点。本文综述了由CNTs催化的ODH反应类型、催化机理及影响因素,以期为今后CNTs作为催化剂更好地应用于ODH反应奠定理论和实验基础,同时也为进一步发掘CNTs作为其他反应的催化剂提供借鉴。
Carbon nanotubes (CNTs) have unique properties such as large specific surface area, high thermal stability, good electron transfer ability and strong adsorptive capacity. In recent years, CNTs have attracted extensive attention as catalysts for catalytic oxidative dehydrogenation (ODH) reactions. As a non-metallic catalyst for ODH reaction, CNTs has the advantages of high catalytic efficiency, good selectivity, strong stability, small pollution and reusability. In this paper, the types, catalytic mechanisms and influencing factors of ODH catalyzed by CNTs are reviewed in order to lay the theoretical and experimental foundation for the future application of CNTs as a catalyst in ODH reaction, and provide references for further exploration of CNTs as a catalyst for other reactions.
