A floatable photocatalytic nanocomposite to facilitate scale-up of solar hydrogen production

A floatable photocatalytic platform made from a porous elastomer-hydrogel nanocomposite has been developed for converting solar energy into hydrogen fuel. This platform enables efficient light delivery, a facile supply of reactant and rapid product separation to achieve high hydrogen-evolution rates. Large-scale and seawater experiments indicate the potential for scale-up and practical application.11Nsciescopu
