Abstract Fe/Mn bimetallic heterogenized catalyst [Fe/Mn(THPP)@MWCNT] was prepared by the simultaneous attachment of Mn and Fe porphyrins onto the surface of functionalized multi-walled carbon nanotubes. This new bimetallic nanohybrid displays a superior catalytic performance (81%) in comparison with their analogous monometallic counterparts (36% and 44% for Fe- and Mn-porphyrin respectively) in the oxidation of hydrocarbons with molecular oxygen as the sole oxidant. Experiments comparing bimetallic catalyst with equivalent physical mixtures of monometallic catalysts revealed the catalytic synergistic effect amongst metallic active centers onto the surface of the same nanotube, introducing a new class of bimetallic porphyrin-based catalysts for oxidation reactions.

多壁碳纳米管表面改性制备新型双金属 Fe/Mn 催化剂用于碳氢化合物的有氧氧化

摘要 Fe/Mn双金属异质化催化剂[Fe/Mn(THPP)@MWCNT]是通过将Mn和Fe卟啉同时附着在功能化的多壁碳纳米管表面上制备的。在以分子氧作为唯一氧化剂氧化碳氢化合物时，这种新型双金属纳米杂化物与类似的单金属对应物（Fe 和 Mn 卟啉分别为 36% 和 44%）相比，表现出优异的催化性能（81%）。将双金属催化剂与单金属催化剂的等效物理混合物进行比较的实验揭示了同一纳米管表面上金属活性中心之间的催化协同作用，引入了一类新的双金属卟啉基催化剂用于氧化反应。
