摘要

采用简单的水热合成法制备了氧化钼（MoO3）/石墨烯（GNS）/碳纳米管（CNT）复合材料。用扫描电子显微镜（SEM）和X射线衍射仪（XRD）表征了材料的形貌和结构。用循环伏安（CV）和线性扫描（LSV）测试了材料的氧还原催化性能，结果发现，复合材料的氧还原电流和起始电位均大大优于单一的MoO3，表现出较好的催化性能。含有3 mg·cm-2 MoO3/GNS/CNT复合材料作为阴极催化剂的MFC最大功率密度为510 mW·m-2，达到商业铂碳的83%。因此，廉价的MoO3/GNS/CNT复合材料作为MFC阴极氧还原催化剂具有巨大的应用潜力。

Abstract

The MoO3/graphene/carbon nano-tube composites were synthesized via a facile hydrothermal method. The morphology of the materials were observed using scanning electron microscope (SEM) and the structures were characterized

with X-ray diffraction (XRD). The electro catalytic activity of oxygen reduction of the materials were measured by cyclic voltammetry (CV) and linear sweep voltammetry (LSV). The results revealed that the composites exhibited better electro catalytic activity towards oxygen reduction with a higher oxygen reduction current and more positive oneset potential than pure MoO3. The microbial fuel cell assembled with 3 mg·cm-2 MoO3/GNS/CNT composites as cathode catalyst delivered a higher power density of 510 mW·m-2

which was 83% as much as the MFCs using Pt/C-catalyst cathode. Therefore

the inexpensive MoO3/GNS/CNT composites as MFCs cathode oxygen reduction catalyst had great potential for application.
