Catalysts used for releasing hydrogen from an H2O molecule are made from platinum, or molybdenum which are expensive hence the output energy is expensive too. Researchers in Russia used thin films of molybdenum sulfide deposited on the surface of glassy carbon instead. In this case, the material consumption will be minimal, and the surface area of the catalyst will be the same as if it was completely made from molybdenum sulfide. They measured electrochemical characteristics which indicated that the differences in the achievable hydrogen evolution reactions performances of the films could be caused by their unique morphological properties…read more.
