Project summary description:
Methanol is a promising liquid hydrogen carrier for long distance hydrogen transportation and exportation, because it is rich in hydrogen content, low-cost, recyclable between methanol-formaldehyde, and easier to manufacture from renewable resources including biomass waste.

The critical bottleneck in adopting methanol as the carrier is the demanding dehydrogenation process. The project aims to create a new class of photocatalyst based on biomass-derived carbon nanodots grown on transition metal (di)chalcogenide nanosheets that can effectively enable a light-controlled methanol hydrogen release of desired quantity.

The key outcomes of the project will be a new class of photocatalysts and flexible, on-demand hydrogen delivery technology for liquid hydrogen carriers.
