采用微波辐射法制备了氮硫共掺杂石墨烯（NSG），并在其上负载了钯钨（PdW）合金纳米粒子。采用X射线衍射、透射电子显微镜、X射线光电子能谱、循环伏安和扫描电化学显微镜等技术对样品的物理和电化学性能进行了表征。结果表明，PdW合金纳米粒子均匀地分散在NSG表面，PdW/NSG的电化学性能明显优于Pd/NSG和Pd/G。PdW/NSG的电化学性能得到改善的原因被认为是PdW纳米颗粒和NSG之间的强相互作用和协同效应。
Nitrogen and sulfur co-doped graphene (NSG) is prepared by a facile microwave irradiation method and palladium-tungsten (PdW) alloy nanoparticles are supported on the NSG substrate. Several techniques, including X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, cyclic voltammetry and scanning electrochemical microscopy etc. are used to characterize the physical and electrochemical properties of the as-prepared samples. It is found that the PdW alloy nanoparticles are uniformly dispersed on the surface of NSG and the electrochemical performance of PdW/NSG is much better than those of Pd/NSG and Pd/G. The reason for the improved electrochemistry performance of PdW/NSG is considered to be the strong interactions and synergetic effects between PdW nanoparticles and NSG.
