| 英文摘要 | oxygen spillover and back spillover on pt/tio2 catalysts have been studied by a potential dynamic sweep method. the characteristics of i-v profiles of pt/tio2 electrodes in the three potential sweep regions are different from those of pt and tio2 electrodes. the catalytic role of pt/tio2 in oxygen spillover and back spillover is identified. it decreases, and the electrochemical oxygen adsorption (or desorption) increases with elevating temperature of hydrogen post-treatment of pt/tio2; to a certain extent (hydrogen post-treatment of pt/tio2 at 700 degrees c), the control step of oxygen electrode process (anodic oxidation or cathodic reduction) changes from oxygen diffusion to electrochemical oxygen adsorption or desorption, respectively. increasing the amount of pt supported on tio2 enhances the processes of oxygen spillover and back spillover.
