Water splitting for H2 production driven by solar energy is quite attractive while the current efficiency is very moderate due to both the extremely sluggish water oxidation half reaction and limited light harvesting (mostly UV-visible light). In addition, the separation of one product H2 from the other O2 during water splitting is very costly. The project is designed to address these challenges by i) utilizing the fullsolarspectrum (300-2500nm) instead of UV-visible light (300-700nm), ii) coupling watersplitting with biomass-derivative oxidation to avoid water oxidation, iii) well combining solid Z-scheme UV-visible photocatalysis and Infrared-driven thermal catalysis, and iv) using a flow double tube reactor other than batch reactors, thus targeting to produce green H2 from both water and biomass with a high quantum yield of 60% . Furthermore the project will co-produce high-value chemicals with a high selectivity of >90%. In addition, the integration of low-cost and efficient catalysts with novel flow reactors will assure a continuous and efficient production of H2 and high-value chemicals. The entire process does not use fossil fuels nor produce CO2, thus a zero carbon-emission technology. Finally the system can be readily scaled up by numbering up the reactor modules. All these are built upon a multidisciplinary and international consortium with the global experts in photocatalysis, thermal catalysis, reactor engineering, product separation, simulation and social science. Therefore the scientific and technical challenges, as well as the environmental, societal and economic impacts will be fully addressed in the project. The proposed technology will typically benefit the EU economy by an innovative green H2 production process from water and biomass, heavily contributing to a low carbon society. In addition, the international team including members from Asia will facilitate the technology exploitation out of the EU, to further benefit the EU economy.

由太阳能驱动的水分解制氢非常有吸引力，但由于水氧化半反应极其缓慢和光收集有限（主要是紫外-可见光），电流效率非常适中。此外，在水分解过程中将一种产物 H2 与另一种 O2 分离的成本非常高。该项目旨在通过i）利用全太阳光谱（300-2500nm）代替紫外可见光（300-700nm），ii）将水分解与生物质衍生氧化耦合以避免水氧化，iii）很好地结合固体来应对这些挑战Z型紫外可见光催化和红外驱动的热催化，以及iv)使用流动双管反应器而不是间歇式反应器，从而瞄准生产来自水和生物质的绿色 H2，量子产率高达 60%。此外，该项目还将联合生产高价值化学品，选择性>90%。此外，低成本、高效的催化剂与新型流动反应器的集成将确保氢气和高价值化学品的连续高效生产。整个过程不使用化石燃料，也不产生二氧化碳，属于零碳排放技术。最后，可以通过增加反应器模块的数量来轻松扩大系统规模。所有这些都是建立在一个多学科和国际联盟的基础上，该联盟由光催化、热催化、反应器工程、产品分离、模拟和社会科学领域的全球专家组成。因此，该项目将充分解决科学和技术挑战以及环境、社会和经济影响。拟议的技术通常将通过水和生物质的创新绿色氢气生产工艺使欧盟经济受益，为低碳社会做出重大贡献。此外，包括亚洲成员在内的国际团队将促进欧盟以外的技术开发，进一步造福欧盟经济。
