Abstract

Inspired by the solar energy storage process during photosynthesis, we report herein a solar-decoupled photosynthetic biohybrid strategy through integrating a persistent photocatalyst with photoautotrophic microbes for sustainable and all-weather biomanufacturing, allowing for overcoming the intrinsic intermittent nature of solar energy availability by introducing energy storage and release processes. The results demonstrate that the apparent photo conversion efficiency (APCE) for of the persistent catalyst/R. palustris hybrid system reaches 8.30%, much higher than the 4.36% observed in bare R. palustris. Additionally, the proposed solar-decoupled biohybrid strategy not only shows considerable potential in coupling the practical power plant for the capture and utilization of CO₂ from the flue gas but also exhibits universal applicability in different photosynthetic microorganisms. This concept-proving research offers new ideas to extend photocatalysis reactions without in situ irradiation and could pave new ways for sustainable solar energy utilization as well as biomanufacturing in space, where solar energy might be limited.

超越自然合成通过太阳解耦的生物杂交光合系统

受光合作用过程中太阳能储存过程的启发，我们在此报告了一种太阳能解耦光合生物杂交策略，通过将持久性光催化剂与光自养微生物相结合，实现可持续和全天候的生物制造，从而通过引入能量储存和释放过程来克服太阳能可用性固有的间歇性。结果表明，该催化剂的表观光转化效率（APCE）比R。斑马草杂交系统达到8.30%，远高于裸斑马草的4.36%。此外，所提出的太阳能解耦生物混合策略不仅在耦合实际电厂以捕获和利用烟气中的CO2方面显示出相当大的潜力，而且在不同的光合微生物中也具有普遍适用性。这一证明概念的研究为延长光催化反应提供了新的思路，而无需原位辐照，并可能为太阳能的可持续利用以及太阳能可能有限的太空生物制造铺平新的道路。
