title: Regulated Synthesis of Mo Sheets and Their Derivative MoX Sheets (X: P, S, or C) as Efficient Electrocatalysts for Hydrogen Evolution Reactions.
abstract: Electrochemical H2generation from H2O has been focused on the exploration of non-noble metals as well as earth-rich catalysts. In our practical work, we provide a simple cost-efficient fabrication process to prepare large Mo sheets via the controlled equilibrium between sublimation of MoO3and reduction of H2. Porous MoP sheets were synthesized from the obtained Mo sheets as the Mo source and template which exhibit notable activity in the hydrogen evolution reaction with a low onset potential of -88 mV vs RHE, small Tafel value of 54.5 mV/dec, and strong catalytic stability. With Mo sheets as the universal Mo source and template, MoS2and Mo2C sheets were synthesized by a similar process, and the corresponding catalytic activities were calculated by density functional theory.
