Title：Multifield coupled concentrated-solar-driven catalytic water splitting for hydrogen production
Abstract：Solar photocatalytic water splitting hydrogen production is an ideal solution for the future renewable energy supply system. Large-scale hydrogen production relies on the effective coupling of the catalyst particles and solar radiation in the multiphase reaction fluid. In our work, the coupling characteristics of solar concentrating radiation and reaction are regulated. The lens/attenuator group concentrating system is constructed to achieve the continuous modulation of light intensity and successfully coupled with the photocatalytic reaction process. To overcome the mass transfer limitation of water molecules in the catalytic material, a MOF support material with high water transport characteristics is developed to realize the efficient adsorption and desorption of water molecules on the surface of catalytic materials, leading to efficient photothermal hydrogen production under concentrated light condition. For the interfacial bubble dynamics in the process of photothermal splitting water for hydrogen production, a PIV/PLIF method is developed to achieve accurate measurement of the flow and temperature fields around the bubbles. In addition, a magnetically coupled integrated concentrating photocatalytic hydrogen production system is proposed. Furthermore, a solar-photothermal coupled water-splitting hydrogen production system with Fresnel lens and composite parabolic concentrator was constructed. The above work may provide new ideas for the study of multifield coupled concentrated-solar-driven catalytic water splitting for hydrogen production.
