The cathodic process in electrochemical water electrolyzers, the hydrogen evolution reaction (HER), is an extremely important reaction as it produces clean H-2 gas that can be utilized in a fuel cell to create electricity as an energy source for the increasing energy consumption of today's World. Transition metal dichalcogenide (TMD) materials have emerged as a competitor to Pt catalysts for the HER; however, the HER catalytic activity of TMD materials depends on various parameters including their fabrication route. Herein, we present a one-step powderless deposition growth process of 2H-MoS2 and 2H-WS2 materials on their native metals which serve directly as electrodes. The 2H phase TMDs were subsequently partially converted to the 1T-phase by a tert-butyllithium immersion treatment. The 2H and 2H/1T phase TMD foils were utilized for electrochemical hydrogen evolution, and we show that these TMD foils outperform or rival other MoS2 and WS2 materials in the literature fabricated by powder-based deposition/growth techniques. These findings highlight the importance of developing new scalable fabrication routes for HER catalysts in the race toward clean energy production.
