Controllable fabrication and structure evolution of hierarchical 1T-MoS2 nanospheres for efficient hydrogen evolution
文献摘要：
The layered materials have demonstrated great prospects as cost-effective substitutes for precious electrocatalysts in hydrogen evolution reaction.Research efforts have been devoted to synthesizing highly conductive MoS2 with the substantial cardinal plane and edge active sites.Here,we successfully synthesized a hierarchical 1T/2H-MoS2 with sodium ion insertion via a facile hydrothermal method.The contents of the 1T-phase can be flexibly controlled by different hydrothermal temperatures(160～200℃).And the modified uniformly dispersed 1T/2H-MoS2 nanospheres with different d spacings were designed to enhance the electrocatalytic efficiency by adding SiO2 and through the ion exchange process of NaOH and HF solution.The as-synthesized Na+intercalated 1T-MoS2 nanosphere with an expanded interlayer of 0.95 nm obtained at 160℃exhibits a prominent electrocatalytic performance of hydrogen evolution reaction with a comparable overpotential of 255 mV and a remarkably small Tafel slope of 44 mV/decade.Therefore,this study provides a facile and controllable strategy to yield interlayer-expanded 1T-MoS2 nanospheres,making it a potentially competitive hydrogen evolution catalyst for the hydrogen cell.
