摘要
In the present study, we have proposed the phosphorus (P)-doped CoS(2)electrocatalyst through a simple hydrothermal route and utilized as an economical and earth-abundant electrocatalyst for hydrogen evolution reaction (HER). A sequence of P-doped CoS(2)electrocatalysts were obatined by using different NaH(2)PO(4)contents. The as-synthesized samples were characterized by XRD, SEM, HR-TEM, element mapping, and XPS analyses. It is found that these P-doped CoS(2)materials composed of high purity nanoparticles and stacked in a block structure. The electrochemical performance has been investigated in 0.5-M H(2)SO(4)electrolyte. The results indicate that the doping of phosphorus can significantly increase the electrocatalytic hydrogen evolution activity of CoS(2.)Among the different samples, the P-doped CoS(2)attained with 5 mmol of NaH(2)PO(4)contents offers the highest HER performance with a minimum overpotential of 109 mV at 10 mA cm(-2), the smallest Tafel slope of 48 mV dec(-1), and an excellent long-term durability over 1,000 cycles. The analysis results illustrate that the doped phosphorus may change the internal properties of CoS2, which promotes the ability of charge transfer and electrochemical active sites, resulting in the significantly increased HER activity compared with bare CoS2. Therefore, this work demonstrates that a proper doping of phosphorus is a suitable approach to improve the catalytic ability of metal sulfides for HER application.
