Hydrogen evolution reaction on MoS2 electrocatalyst grown by chemical bath deposition |
| 초록 |
Recently MoS2 has attracted great attention as an electrochemical catalyst for hydrogen evolution reaction (HER). Here we report chemical bath deposition of the MoS2 catalyst for HER. MoS2 was deposited at 90 ℃ on carbon fiber papers (CFP) in an aqueous solution which contains ammmonium molybdate and thioacetamide as Mo and Sulfur precursors, respectively. The catalyst of MoS2/CFP, which was grown for 30 min in the chemical bath, exhibited a small overpotential of 156 mV vs. RHE to reach a cathodic current density of 10 mA/cm2 in 0.5 M H2SO4 solution. In addition, the Tafel slope and exchange current density of the catalyst were 44 mV/dec and 3.03 μA/cm2, respectively. |
