Scientists at Rice University and the Lawrence Livermore National Laboratory have predicted and created new two-dimensional electrocatalysts—low-cost, layered transition-metal dichalcogenides (MX 2 ) based on molybdenum and tungsten—to extract hydrogen from water with high performance and low cost. Schematic of the proposed mechanism for the morphology change, in which hydrogen evolution at basal-plane sites of stacked layers causes perforation and exfoliation.
