Hydrogen evolution catalysis on amorphous MoS2/carbon fiber paper grown by hydrothermal Method |
| 초록 |
Transition metal dichalcogenides (TMD’s), particularly molybdenum disulfide (MoS2), have been identified as excellent hydrogen evolution reaction (HER) catalyst for the water splitting reaction. In this work, we directly grow amorphous MoS2 thin films on plasma pre-treated carbon fiber paper (PP-CFP) and electrochemically pre-treated carbon fiber paper (EP-CFP) to prepare catalyst for the HER. The amorphous films are synthesized at 200 oC by simple hydrothermal method. The MoS2/PP-CFP and MoS2/EP-CFP show more excellent cathodic current density of the HER than the crystalline MoS2 catalysts. In addition, Tafel slopes of 48 and 52 mV per decade are measured for MoS2/EP-CFP and MoS2/PP-CFP, respectively, which suggests the Volmer-Heyrovsky mechanism of hydrogen evolution. Furthermore both samples exhibit so excellent stability that cathodic current density slightly decreases after 1000 cycles of the HER experiment. |
