摘要

采用简单、无模板的方法制备了氮掺杂多孔石墨烯/碳复合材料(NPGC)。采用SEM、XRD、Raman、XPS等分析手段对NPGC的形貌、组成以及结构进行了表征，利用旋转圆盘电极技术测试了其电催化氧还原反应(ORR)活性。结果表明，葡萄糖在水热后生成的碳与石墨烯成功复合，并在950℃炭化、活化后形成了相互渗透、结构良好的三维片状多孔网络结构；其氮含量高达9.47%。NPGC作为一种高效的非金属ORR电催化剂，在碱性溶液中具有较高的起始电位[0.87 V(

RHE)

]

和较大的极限电流密度(4.7 mA∙cm

-2

)，以及其ORR平均转移电子数为3.8。与商业Pt/C催化剂相比，NPGC具有较强的耐甲醇性和长期耐久性，且制备成本较低，具有广阔的应用前景。

Abstract

Nitrogen-doped porous graphene/carbon composites(NPGC) were prepared by a simple and template free method.Its morphology

composition and structure were characterized by SEM

XRD

Raman and XPS. The electrocatalytic performance of NPGC on oxygen reduction reaction(ORR) was measured by a rotating disk electrode. The results showed that porous carbon generated by hydrothermal treatment of glucose was successfully compounded with graphene. After carbonization and activation at 950℃

a three-dimensional lamellar porous network structure with good permeability and structure was formed. The N content of NPGC is as high as 9.47%. NPGC showed relatively high initial potential [0.87 V(

RHE)

]

and limiting current density (4.7 mA∙cm

-2

) for ORR in KOH solution

and the average number of ORR transferred electrons was 3.8. Compared with commercial Pt/C electrocatalyst

NPGC showed high methanol tolerance and long-term durability

and had the advantage of low preparation cost

which has broad application prospects in industry.
