Ultra-Stable Hydrogen Evolution Catalyst
Hydrogen generation for energy as an ideal, clean and highly efficient secondary energy resource. Current state-of-the-art uses traditional Pt catalysts for hydrogen generation, which the evolution process is expensive, scarce and unstable. This calls for a new catalyst material that is stable, inexpensive and easily available.
We introduce a new hydrogen evolution catalyst based on transition metal dichalcogenides (TMDCs). This ultra-stable catalyst, specifically, molybdenum disulfide (MoS2), incorporating ~10 wt% platinum loading, is able to generate stable hydrogen evolution activity for 120,000s ~ 33.3 hours at a current density up to 50 mA/cm2. The performance of this TMDC-Pt catalyst was benchmarked against traditional 40 wt% Pt/C catalyst, which shows increasing losses (increasing over potential), as illustrated in Fig. 1.
