采用光化学还原法制备了磷钼酸还原氧化石墨烯(PMoA-rGO)纳米复合材料。通过紫外-可见光谱、扫描电子显微镜图像、傅里叶变换红外光谱、拉曼光谱和X射线光电子能谱对其进行了表征，以证实PMoA取代了GO上的含氧官能团，并在光还原过程中将GO还原为rGO。用循环伏安法对PMoA-rGO的电化学性质进行了研究，结果表明，PMoA-rGO修饰的玻碳电极在酸性溶液中通过快速、表面控制的电子转移过程具有较高的电催化活性。结果表明，由于rGO的高导电性，不仅增加了其电活性表面积，还促进了电子的转移。
Phosphomolybdic acid-reduced graphene oxide (PMoA-rGO) nanocomposites are fabricated by a photochemical reduction method. They are characterized by ultraviolet-visible spectra, scanning electron microscope images, Fourier transform infrared spectroscopy, Raman spectra and X-ray photoelectron spectroscopy in order to confirm that oxygen-containing functional groups on GO are replaced by PMoA and that GO is reduced to rGO in the photo-reduction process. The electrochemical properties of PMoA-rGO are investigated by cyclic voltammetry, which shows that the PMoA-rGO modified glassy carbon electrode has high electrocatalytic activity in acid solution via a fast, surface-controlled electron transfer process. The results indicate that the use of rGO not only increases the electroactive surface area, but also facilitates electron transfer due to its high electric conductivity.
