二硫化钼纳米片(MoS_(2))是一种有望取代贵金属材料、非常有前景的电催化析氢材料。MoS_(2)不足在于导电性较差,析氢反应(her)能垒较高。为了克服这一缺点,我们引入制备简单、导电性良好的Mo_(2)N作为基体。通过水热法,将MoS_(2)纳米片均匀生长在Mo_(2)N颗粒表面,一方面增加了材料导电性,另一方面MoS_(2)与Mo_(2)N形成MoS_(2)/Mo_(x)N异质结构有效增强水分子的解吸,从而提高her性能。利用X射线衍射仪(XRD)、X射线光电子能谱仪(XPS)、扫描电子显微镜(SEM)、电化学工作站对MoS_(2)/Mo_(x)N进行结构、形貌以及性能的表征。实验结果表明,MoS_(2)纳米片均匀生长在Mo_(2)N颗粒表面,形成异质结构,水热12 h所得材料性能最佳。以MoS_(2)/Mo_(x)N作为工作电极,碳棒与Ag/AgCl电极分别作为对电极和参比电极,进行her测试。在-10 mA/cm^(2)下过电位仅为248 mV,Tafel斜率为93.5 mV/dec,稳定性良好。

钼基MXenes在电化学生物分子传感、电催化和能源储存等领域具有重要应用潜力。然而，制备钼基MXenes的传统方法是使用强腐蚀性HF溶液刻蚀Mo基MAX相(三元层状碳化物)制得，实验危险性高且制备周期长。本文提出通过路易斯酸熔盐法选择性刻蚀Mo2Ga2C前驱体制备Mo2CTxMXene，降低危险性并大幅提升制备效率，并研究了刻蚀温度和保温时间对Mo2CTxMXene物相和微观结构的影响。研究表明，使用HF无法完全刻蚀Mo2Ga2C前驱体制得高纯度Mo2CTxMXene，而熔融盐法在600 °C下仅需30 min即实现完全刻蚀。此外，熔融盐法制备的Mo2CTxMXene在碱性电解液中具有优异的电催化析氢(her)电催化活能，并具有长期稳定性，在10 mA·cm-2的电流密度下有着较低的过电位和Tafel斜率，分别为114 mV和124 mV·dec-1。

39 mol% SiC of ceramic pellets ZrB2-αSiC and TiB2-αSiC were synthesized by the reactive hot pressure RHP process at 1850°C under 40 Mpa in vacuum. The XR diffraction displays the absence of other reagents apart from ZrB2, SiC and TiB2 confirming the purity of the pellets. The cathodic exploitation of both of them through electrochemical study shows that TiB2-αSiC is the most active for Hydrogen Evolution Reaction (her) and Hydrogen Oxidation Reaction (HOR) in 0.5 M of H2SO4 solution at room temperature. Moreover, the kinetic exploitation shows that for both pellets the system is controlled by mass transport when they are used as her. However, in the case of HOR, the system is controlled by the electron transfer.
