Biomass-derived Carbon Dots Enable Flexible, On-Demand Hydrogen Delivery

甲醇具有含氢量丰富、价格低廉、可在甲醇-甲醛之间循环利用、易于从生物质废弃物等可再生资源中制备等优点，是一种很有前途的长距离氢气运输和出口液氢载体。采用甲醇作为载体的关键瓶颈是苛刻的脱氢过程。该项目旨在创造一种基于过渡金属（di）硫族纳米片上生长的生物质衍生碳纳米点的新型光催化剂，这种纳米点可以有效地实现所需数量的光控甲醇H2释放。关键成果将是一种新型的光催化剂和灵活的液氢载体按需氢输送技术。

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.
