Hydrogen evolution reaction at different pH of 2D MoS2 prepared via liquid-phase exfoliation
Original language description
This study reports the successful preparation of exfoliated MoS2 structures from the bulk powder using liquidphase exfoliation (LPE), leading to a significant improvement in electrochemical properties for the hydrogen evolution reaction (HER) without modification of the flakes. Utilizing green solvent systems, acetone/water and butanol/ethanol, the study highlights the importance of solvent selection and optimization for achieving efficient exfoliation and catalytic performance. The acetone/water system, with an optimal ratio of 45/55, produced uniform 2D MoS2 flakes with enhanced catalytic performance, especially in acidic media, where the samples exhibited high current densities and efficient charge transfer. After 2000 HER cycles, this system achieved an overpotential of 365 mV at -10 mA & sdot;cm-2, demonstrating both performance and stability improvements. Although less efficient overall, the butanol/ethanol system showed promising results in alkaline conditions with best ratio of 30/70. These findings confirm the importance of solvent selection in MoS2 exfoliation and highlight the potential of this material as a catalyst for hydrogen production. Further optimization of solvent ratios could enhance the catalytic efficiency of MoS2 for energy applications and scalability for industrial applications.
