Project summary description:
This project aims to develop a new concept of monolithic membranes composed of photocatalysts embedded in highly efficient solar thermal graphene. Such a membrane will be a first of its kind and would be able to utilise the full solar spectrum for scalable seawater desalination and direct splitting to produce hydrogen without the need to concentrate sunlight.

Expected outcomes include chemically and structurally tailored membranes and 2D floating prototypes for real life hydrogen production, and in-depth understanding of the working mechanism to facilitate up-scaled renewable hydrogen generation.
