在没有模板的情况下，通过水热方法制备了一种具有层次性的MoS2/ moo2纳米结构的析氢反应催化剂。研究了各种钼源的影响，并讨论了mos2壳层和moo2核的作用。研究发现，由moo2纳米带衍生的MoS2/ moo2纳米结构具有最佳的HER活性，且HER性能受MoS2壳层和moo2核层相对含量的强烈影响，二者分别对应于质量传递能力和电子转移能力。
A hierarchical MoS2/MoO2nanostructure is presented as a highly efficient catalyst for the hydrogen evolution reaction (HER), which is prepared via a facile hydrothermal route in the absence of templates. The influence of various Mo sources has been studied and the roles of MoS2shell and MoO2core are discussed. It is found that the MoS2/MoO2nanostructures derived from the MoO2nanobelts exhibit the best HER activity, and the HER performance is strongly affected by the relative contents of MoS2shell and MoO2core, which correspond to the mass transport ability and the electron transfer ability, respectively.
