Scientists synthesize what could be a low-cost, earth-abundant material that splits water to make hydrogen fuel.
Storing energy from sunlight or wind inside the bonds of a hydrogen (H2) molecule would let intermittent renewable energy power fuel cells, providing electricity on demand. The scalable production of H2, created by splitting apart water (H2O), depends on how well the catalysts drive the reaction. Thus far, platinum catalysts are the best, but the metal’s scarcity and cost is problematic. A layered material shows great promise as a low-cost alternative. Scientists showed that a microwave synthesis technique helps create the new material, a nanostructured molybdenum disulfide, and gives the catalyst an improved ability to produce hydrogen.
Microwave-prepared molybdenum disulfide material has the potential to be an affordable alternative to the expensive platinum catalysts that are currently used. The performance exceeds that of MoS2 materials made via other synthetic methods.
