| 英文摘要 | the ptsn/c-ni catalyst was prepared by adding ni(no3)(2) in the reduction process of sncl2, and h2ptcl6 with ethylene glycol. the coexistence of the sn(ii) /sn(iv) redox couple was detected in the catalyst by temperature-programmed reduction experiments. linear sweep voltammetry, single cell test, and co stripping voltammetry experiments showed that the ethanol electro-oxidation activity and co tolerance can be obviously enhanced by increasing the sn(h)/sn(iv) ratio in the catalyst. the reason might be attributed to that the sn(ii)/sn(iv) redox couple accelerates the transfer rate of (oh)(ads) and then promotes the consequent oxidation of co-like intermediates that are produced in the ethanol electro-oxidation process on the surface of pt. |
