                 摘要:以钼酸铵和氯铂酸为原料,通过原位程序升温碳化过程,合成了 Pt 负载量不同的 Pt/Mo x C y (x∶y≤2)催化
                 剂,并考察了其在电解水析氢反应(HER)中的催化性能。利用 XRD、BET、SEM、TEM、XPS 对催化剂的微
                 观结构及物理化学性质进行了表征。结果表明,Pt 的负载改变了碳化钼形成的拓扑结构,Pt 负载后的样品更容
                 易形成 α-Mo 2 C 相。Pt 的负载量对碳化钼催化剂在 HER 反应中的催化性能具有显著影响,1.6Pt/MoC
                 〔n(Pt)∶n(Mo)=1.6∶98.4〕催化剂表现出最优催化效果(过电势 η onset =108 mV,塔菲尔斜率 b=74 mV/dec)及
                 较低的阻抗(18.77 Ω),可以与商业 Pt/C 催化剂相媲美。

                 Abstract: Pt/Mo xC y(x∶y≤2) catalysts  with  different Pt loadings were synthesized using ammonium
                 molybdate and chloroplatinic acid as raw materials through in situ temperature-programmed carbonization
                 process and their catalytic activities in the hydrogen evolution reaction (HER) of electrolyzed water were
                 investigated. Their microstructure and physicochemical properties were characterized by XRD, BET, SEM,
                 TEM and  XPS.  The results showed that  the introduction  of  Pt changed the topological structure of
                 molybdenum carbide during the carbonization process and made the prepared samples easier to form the
                 α-Mo 2C phase. The loading of Pt had a significant effect on the catalytic activity of molybdenum carbide
                 catalyst in the HER reaction. Among the samples, the 1.6Pt/MoC  〔n(Pt) ∶n(Mo)=1.6 98.4∶  〕catalyst
                 exhibited the best catalytic activity (overpotential η onset=108 mV, Tafel slope b=74 mV/dec) and had lower
                 impedance (18.77 Ω), which could be comparable with the commercial Pt/C catalyst.
