2D/2D heterojunction interfaces of 1T-MoS2 and Ti3C2 MXene: designing high-performance catalyst for the hydrogen evolution reaction
Source abstract
Abstract
Designing efficient electrocatalysts for the hydrogen evolution reaction (HER) is crucial for advancing sustainable energy technologies. In this study, a 2D/2D heterostructure composed of 1T-phase molybdenum disulfide (1T-MoS 2 ) and titanium carbide MXene (Ti 3 C 2 T x, denoted as Ti 3 C 2 ) is synthesized using a one-step hydrothermal method. The hybrid catalyst exhibits improved HER kinetics, demonstrated by a low overpotential of 248 mV at 10 mA cm −2 and a Tafel slope of 55 mV dec −1 , indicating fast reaction kinetics and favorable charge transfer. The addition of tetramethylammonium ions (TMA + ) induces interlayer expansion, increasing the 1T phase content to 89%. Incorporating only 1% Ti 3 C 2 MXene suppresses oxidation and enhances stability. The composite demonstrates a large electrochemical surface area, high turnover frequency (TOF), and retains over 90% of its catalytic activity after extended electrolysis. This scalable approach offers a promising route to developing stable, efficient 2D electrocatalysts for hydrogen production.
