摘要

仿生超分子组装为实现更高效率的人工光合作用提供了一种有效的策略。采用液-液相分离(LLPS)技术构建了一种基于聚金属氧酸盐(POM)的人造叶绿体,该叶绿体可以模拟光催化水氧化过程。这样的结构在有限空间内表现出极大的析氧速率和良好的可回收性。具体来说,以化学计量学的方式将带正电的聚电解质与带负电的牺牲电子受体(SEA)混合,产生凝聚液滴,从而捕获POM分子。一个结构明显皱褶的微反应器组装完成。自发地,同质到异质的转变使POM在人工设计的微反应器中具有优异的可回收性、可重用性和结构稳定性。因此,光催化水氧化生成O2的效率比均匀状态下的POM显著提高。该研究为将多个功能化组分集成到一个系统中以提高光合作用性能开辟了新的途径,在实际应用中具有很大的潜力。

Artificial Chloroplast Nanoarchitectonics through Liquid-Liquid Phase Separation Enables Recycled and Enhanced Photosynthesis.

Biomimetic supramolecular assembly offers a potent strategy to achieve artificial photosynthesis with higher efficiency. We constructed a polyoxometalate (POM)-based artificial chloroplast through liquid-liquid phase separation (LLPS), which efficiently mimics the photocatalytic water oxidation process. Such an architecture shows a greatly enhanced oxygen evolution rate with excellent recyclability in a confined space. To be specific, mixing a positively charged polyelectrolyte with a negatively charged sacrificial electron acceptor (SEA) in a stoichiometric manner creates coacervate droplets so as to entrap POM molecules. A microreactor with an obviously wrinkled structure is assembled. Spontaneously, a homogeneous-to-heterogeneous transformation enables POM to possess excellent recyclability, reusability, and structural stability occurring in an artificially designed microreactor. As a consequence, the efficiency of photocatalytic water oxidation to produce O2 is remarkably improved compared to that of POM in the homogeneous state. This work opens a new avenue to integrate multiple functionalized components into one system to improve photosynthetic performance, which holds great potential in real applications.
