摘要:

分别制备合成了碳载5单羧基10,15,20三苯基钴卟啉(CoMCP)、 铁卟啉(FeMCP)、 锰卟啉(MnMCP)、 铜卟啉(CuMCP)和镍卟啉(NiM
CP)复合催化剂, 并通过线性电势扫描法研究该复合材料对氧还原的电催化性能和抗甲醇能力. 结果表明: MnMCP对氧还原有较高的电催化活性, 其氧还原起始电位为0.513 V, 催化性能最好; 其他金属复合材料按照CoMCP,FeMCP,CuMCP顺序降低, 而NiMCP的起始电位仅为0.198 V, 对氧还原的催化性能相对最弱; 在抗甲醇性能测试中, CoMCP,FeMCP,CuMCP,NiMCP的氧还原起始电位正移, 具有较好的抗甲醇能力.

Abstract:

Carbonsupported CoMCP,FeMCP,MnMCP,CuMCP,NiMCP as cathodic catalyst were prepared. And the performance of MeMCP electrocatalysts was investigated by linear sweep vol\|tammetry(LSV). The electrochemical measurements demonstrate that MeMCP catalysts have good catalytic activity. The initial potential of MnMCP is 0.513 V, which has better catalytic performance. However, the initial potential of NiMCP is 0.198 V, which is the lowest among the five central metal catalysts. DMFC test shows that CoMCP,FeMCP,CuMCP and NiMCP have good catalytic performance in the DMFC.

Key words: direct methanol fuel cell, MeMCP, catalytic oxygen reduction, linear sweep voltammetry(LSV)
