描述了一种形成二硫化钼与金属复合材料的界面途径。金属沉积发生在液相|界面，在预吸附的MoS2膜上。在电化学控制下（两种不混溶电解质溶液之间的界面），在mos2修饰的水/1,2，-二氯苯界面上沉积Cu和Pd。这两种金属的形态差异与它们不同的生长方式有关。分析了伏安测量结果，阐明了界面二硫化钼膜对金属还原和生长的影响。总的来说，MoS2薄膜对金属沉积反应有影响，影响程度取决于金属前驱体的性质。
An interfacial route is described to form composites of molybdenum disulfide with metals. Metal deposition occurs at the liquid| liquid interface, on to the pre-adsorbed MoS2 film. The method is exemplified via the interfacial deposition of Cu and Pd at the MoS2-modified water/1,2,-dichlorobenzene interface, under electrochemical control (interface between two immiscible electrolyte solutions). Differences in morphology between the two metals are related to their differing modes of growth. The voltammetric measurements were analysed to elucidate the effect of the interfacial MoS2 film on the reduction and growth of the metals. Overall, the MoS2 film was found to impact the metallic deposition reaction, and the effect depends on the nature of the metallic precursor.
