摘要:
以二氧化铅（PbO2）和还原氧化石墨烯(RGO)为原料，采用水热法制备掺氮还原氧化石墨烯(NRGO)负载PbO2纳米复合材料PbO2/NRGO，并采用线性扫描伏安法（LSV）检测其氧还原（ORR）电催化性能。研究结果表明，该纳米复合物在碱性条件下具有较好的催化活性（E1/2=0.68 V）；12 000 s后，在碱性介质中相关电流比仍有62.35%（商业Pt/C催化剂的相关电流比值为49.91%），其稳定性和甲醇抗毒性均优于商业Pt/C催化剂。扫描电镜和拉曼的样品表征结果显示，其反应机理是PbO2颗粒作为助催化剂，增大了NRGO的比表面积，使活性位点增加，进而增加了其催化活性。
Abstract:
The nanocomposites of PbO2 nanoparticles and N-doped reduced graphene oxide（PbO2/NRGO）were synthesized by the hydrothermal method. PbO2 and N-doped reduced graphene oxide were used as the starting materials. The electrocatalytic performance of the nanocomposite in ORR was tested by linear sweep voltammetry (LSV).Results show that that PbO2/NRGO-0.9 exhibit remarkable catalytic activity in the alkaline solution (E1/2=0.68V). The relative current ratio in alkaline medium was still 62.35% after 12 000 seconds while that of the commercial Pt/C was 49.91% after 12 000 seconds. Such results indicate that the stability and methanol tolerance of this sample are better than those of commercial Pt/C. The scanning electron microscope and Raman sample characterization reveal the mechanism, i.e., when PbO2 granules are used as the catalyst, the specific surface area of NRGO is increased and the active sites are increased, thus facilitating the catalytic activity.
