随着不可再生能源的急剧消耗以及众多环境污染问题的出现,人类对“绿色”能源的需求也更加迫切。作为众多“绿!色”能源的一种,直接甲醇燃料电池(DMFC)可以将甲醇和氧化剂的化学能直接转化成电能。由于其燃料廉价、结构简单、!能量密度和转换率高及近乎零污染等优点,这种燃料电池吸引了众多研究者的关注。目前,直接甲醇燃料电池使用的电!极催化剂大多为铂基催化剂,而这种催化剂制备成本高,催化活性及稳定性差,严重阻碍了DMFC的商业化。因此,合成 With the rapid consumption of non-renewable energy and the emergence of many environmental pollution problems, the human demand for “green” energy is even more pressing. As one of the many “green” energy sources, direct methanol fuel cells (DMFCs) convert the chemical energy of methanol and oxidizer directly into electricity. Due to its low fuel cost, simple structure, high energy density and conversion efficiency, and near-zero contamination, this fuel cell has attracted the attention of many researchers. At present, most of the catalysts used in direct methanol fuel cells are platinum-based catalysts. However, this catalyst has high preparation cost, poor catalytic activity and poor stability, which seriously hinders the commercialization of DMFC. Therefore, synthetic
