碳纳米管负载四硝基金属酞菁-MnO2双催化剂催化氧还原性能
Catalytic Oxygen Reduction Property of Carbon Nanotubes Supported Tetra-nitro-metal Phthalocyanines-MnO2 Dual Catalysts
摘要
Abstract
The transition metal phthalocyanine has a high catalytic activity for oxygen reduction. MnO2 can catalyze the oxygen reduction reaction. However, the use of transition metal phthalocyanine and MnO2 as dual catalysts for oxygen reduction is quite few. Four types of carbon nanotubes supported tetra-nitro-metal phthalocyanines assemblies (CNT/TNMPc) were synthesized by phthalic anhydride-urea method. Dual catalyst CNT/TNMPc-MnO2 was prepared via adding γ-MnO2 into CNT/TNMPc. The optimal ratio of CNT/TNMPc to MnO2 was obtained by means of cyclic voltammetry. Effects of central metal ions of CNT/TNMPc on the catalytic performance for oxygen reduction reactivity were investigated. The results show that the catalytic efficiency order of the dual catalyst for oxygen reduction reactivity is CNT/TNFePc-MnO2> CNT/TNCoPcMnO2> CNT/TNNi Pc-MnO2> CNT/TNCuPc-MnO2. All of those suggest that the catalytic activity of dual catalysts for oxygen reduction reaction is mainly affected by the nature of metal ions. In addition, the anti methanol performance of dual catalyst was tested in 0. 1 mol/L KOH + 0. 5 mol/L CH3OH electrolyte solution.The results indicate that methanol-tolerant abilities of the CNT/TNMPc-MnO2 are excellent.关键词
