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H2生产的水分裂非常有吸引力，而由于极度缓慢的水氧化半反应和有限的光收获（主要是紫外线可见光），目前的效率非常中等。另外，在水分解过程中，一种产品H2与另一种O2的分离非常昂贵。 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)使用除批处理反应器以外的流动双管反应器，从而靶向从水和生物质中产生绿色H2，高量子产率为60％。此外，该项目将共同生产高价值化学物质，高选择性> 90％。此外，低成本和有效的催化剂与新型流动反应器的整合将确保H2和高价值化学物质的连续有效产生。整个过程不使用化石燃料或生产CO2，因此是零碳排放技术。最后，可以通过编号反应堆模块来容易地扩展系统。所有这些都是建立在全球光催化，热催化，反应堆工程，产品分离，模拟和社会科学领域的全球专家的跨学科和国际联盟上的。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。提出的技术通常将通过从水和生物量的创新的绿色H2生产过程中受益于欧盟经济，从而为低碳社会做出了巨大贡献。此外，包括亚洲成员在内的国际团队将促进欧盟的技术开发，以进一步使欧盟经济受益。
