| 1 | A General Method for the Synthesis of Hybrid Nanostructures Using MoSe_(2) Nanosheet-Assembled Nanospheres as Templates显示文摘The layered transition metal dichalcogenides(TMDs)and transition metal phosphides are low-cost,earth-abundant,and robust electrocatalysts for hydrogen evolution reaction(HER).Integrating them into hybrid nanostructures is potentially promising to further boost the catalytic activity toward HER based on their synergistic effects.Herein,we report a general method for the synthesis of a series of MoSe_(2)-based hybrid nanostructures,including MoSe_(2)-Ni_(2)P,MoSe_(2)-Co_(2)P,MoSe_(2)-Ni,MoSe_(2)-Co,and MoSe_(2)-NiS,by postgrowth of Ni_(2)P,Co_(2)P,Ni,Co,and NiS nanostructures on the presynthesized MoSe_(2) nanosheet-assembled nanospheres,respectively,via a colloidal synthesis method.As a proof-of-concept application,the as-synthesized hybrid nanostructures are used as electrocatalysts for HER,exhibiting high activity and stability in acidic media.Among them,the MoSe_(2)-Co_(2)P composite shows the highest HER activity with an overpotential of 167 mV at 10 mA cm^(-2). | Shikui Han Kai Zhou Yifu Yu Chaoliang Tan Junze Chen Ying Huang Qinglang Ma Ye Chen Hongfei Cheng Weijia Zhou Hua Zhang | 2019 | Research2019，，1： | 1 |
