Ni2P/MoS2 interfacial structures loading on N-doped carbon matrix for highly efficient hydrogen evolution
文献摘要：
Electrochemical catalysts for the hydrogen evolution reaction(HER)have attracted increasing attentions.Noble metal-free cocatalysts play a vital role in HER applications.Herein,a novel strategy to prepare a Ni2P/MoS2 cocatalyst through a simple hydrothermal-phosphorization method was reported,and the prepared cocatalyst was then loaded on an N-doped carbon substrate with excellent conductive performance.The large surface area of the carbon substrate provided many active sites,and the interface between Ni2P and MoS2 improved the catalytic per-formance for the HER.Compared with pure Ni2P catalyst and MoS2 catalyst,the prepared Ni2P/MoS2 cocatalyst exhibited enhanced catalytic performance.In addition,the results indicate that the prepared cocatalyst has a wide pH range and low onset potential values of 280,350 and 40 mV in acidic,phosphate-buffered saline and alkaline solutions,respectively,and the corresponding Tafel slopes are 75,121 and 95 mV dec-1,respectively.Density functional theory(DFT)was adopted to calculate the hydrogen adsorption free energy(AGH*).The results showed that the interface between Ni2P and MoS2 reduced AGH,which was beneficial to the adsorption of hydrogen.Present preparation of cocatalysts with unique interfaces provides a new strategy for improving the catalytic performance of HER.
