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.

太阳能驱动的水分解制氢非常有吸引力，而电流效率非常适中，因为水氧化半反应极其缓慢，光收集有限(主要是紫外可见光)。此外，在水分解过程中将一种产物H2与另一种O2分离是非常昂贵的。该项目旨在通过i)利用全太阳能光谱(300-2500 nm)而不是紫外可见光(300-700 nm)，ii)将水分解与生物质衍生氧化相结合以避免水氧化，iii)将固体Z方案紫外光催化和红外驱动热催化很好地结合在一起，以及iv)使用间歇式反应器以外的流动双管反应器，从而目标是从水和生物质中生产绿色氢气，从而获得60%的高量子产率。此外，该项目将联合生产高价值化学品，选择性高达&gt；90%。此外，将低成本和高效率的催化剂与新型流动反应器相结合，将确保连续高效地生产氢气和高价值化学品。整个过程不使用化石燃料，也不产生二氧化碳，因此是一项零碳排放技术。最后，通过增加反应堆模块的编号，可以很容易地扩大系统的规模。所有这些都建立在一个多学科的国际联盟的基础上，该联盟拥有光催化、热催化、反应堆工程、产品分离、模拟和社会科学方面的全球专家。因此，科学和技术挑战以及环境、社会和经济影响将在该项目中得到充分解决。拟议中的技术通常将通过一种创新的利用水和生物质生产氢气的绿色工艺使欧盟经济受益，从而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为欧盟以外的技术开发提供便利，进一步造福欧盟经济。
