Abstract:
A non-noble metal oxygen reduction reaction (ORR) catalyst labeled as Co-C-N(800) was synthesized by heat-treating a mixture of urea, cobalt chloride and acetylene black for 2 h at 800 oC in an inert nitrogen atmosphere. X-ray diffraction pattern indicates that a metallic β-Co is generated after the heat-treating process. The results from cyclic voltammograms show that the obtained Co-C-N(800) catalyst has good ORR catalytic activity in 0.5 mol/L H2SO4 solution. The catalyst is also good at methanol tolerance and stability in the acidic solution.

摘要:
机械研磨尿素、氯化钴、乙炔黑混合物并经800 oC热处理后,制备出了非贵金属Co-C-N(800)催化剂. X射线衍射测试表明催化剂中有单质β-Co生成. 用循环伏安法表征了催化剂的电化学特性,结果表明Co-C-N(800)具有良好的催化活性和耐甲醇性能. 45 h浸泡实验表明,催化剂在酸性电解液中具有较好的稳定性.
