摘要
直接乙醇燃料电池(DEFC)因为其能量密度高,稳定性好,存储方便和毒性低等优势使其应用得到推广。对催化剂研究和载体研究是提高醇类电氧化效率的两种方法。铂作为阳极重要金属,克服其不稳定性及电催化能力和抗CO中毒能力成为科研者努力的方向~(【1】)。过渡金属氧化物载体不仅因为其能抵抗酸性和氧化环境中的腐蚀,而且能与铂产生相互作用提高铂的电催化性质~(【2)】。本实验所合成的NiC o2o4修饰的石墨烯载铂催化剂(pt-NiCo_2O_4/rGO)在酸性介质中对乙醇电电催化氧化具有很高的催化活性及抗中毒能力和稳定性,在燃料电池的研究中有很好的应用前景。
Direct ethanol fuel cells(DEFC) has so many advantges, so it can be widely used. It hsa two methods to increase the alcohol electro oxidation efficiency. To overcome disadvantages of Pt based catalysts is become the direction of the research effort. Transition metal oxide support not only because it can resist corrosion in acid oxidation environment, but also can interact with pt to improve the electrocatalytic properties of pt. In this experiment, the NiCo_2O_4 modified graphene supported platinum catalyst in acidic medium on the electrocatalytic oxidation of ethanol has a high catalytic activity, anti poisoning ability and stability, it will has a good application prospect.
