  • Methods for producing hydrogen using nanoparticle-catalyst mixtures
    Patent number: 10471409
    Abstract: Provided are compositions for and methods of producing hydrogen. For example, the compositions comprise nanocrystals, a catalyst, a source of electrons, and an aqueous medium. The nanocrystals, catalyst, aqueous medium, and, optionally, the source of electrons are present as a mixture. The methods produce hydrogen by exposing the compositions to electromagnetic radiation (e.g., solar flux).
