Methanol is a promising liquid hydrogen carrier for long distance H2 transportation and exportation, because it is rich in hydrogen content, cheap, 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 H2 release of desired quantity. The key outcomes will be a new class of photocatalysts and flexible, on-demand hydrogen delivery technology for liquid hydrogen carriers.

甲醇含氢量丰富，价格低廉，在甲醇-甲醛之间可回收利用，更易于从生物质废弃物等可再生资源中制取，是一种很有前途的液氢长途运输和出口载体。采用甲醇作为载体的关键瓶颈是苛刻的脱氢工艺。该项目旨在创造一种基于生物质衍生的碳纳米点的新型光催化剂，这些碳纳米点生长在过渡金属(二)硫化物纳米片上，可以有效地实现所需数量的光控制甲醇氢气的释放。关键成果将是一种新型的光催化剂和用于液态氢载体的灵活的按需氢输送技术。
