用旋转环盘法研究了293-333 K温度范围内Ag单晶表面的氧还原反应。总之，反应通过4 e（-）反应途径进行，形成非常少（约0.5-2%）的过氧化物。在相同的温度和过电位下，氧化还原反应动力学总是以（100）的数量级增加
The rotating ring disk method is applied to investigate the oxygen reduction reaction on Ag single-crystal peratures, the oxygen reduction surfaces in alkaline solution over the temperature range 293-333 K. At all tern reaction proceeds through the 4e(-) reaction pathway with a very small (approximate to 0.5-2%) peroxide formation. At the same temperature and overpotentials, the kinetics of the ORR always increases in the order (100)
