通过将用于光捕获的疏水性油酸封端的 CdSe 量子点 (QD) 和用于质子还原的两亲性 [FeFe]-氢化酶亚基模拟物共同嵌入磷脂囊泡膜中，制备了用于在纯水溶液中生产氢气的光催化混合系统。这些仿生功能化囊泡将催化亚基集中在一起，并在抗坏血酸存在下表现出光驱动的氢生成，导致膜结合催化剂和量子点的催化转换率分别为 651 和 2.47 x 105。
A photocatalytic hybrid system for the production of hydrogen in purely aqueous solution was prepared by the co-embedding of hydrophobic oleic acid capped CdSe quantum dots (QD) for light harvesting and an amphiphilic [FeFe]-hydrogenase subunit mimic for proton reduction into phospholipid vesicle membranes. These bio-inspired functionalized vesicles concentrate the catalytic subunits in close proximity and show light-driven hydrogen generation in the presence of ascorbic acid resulting in 651 and 2.47 x 105 catalytic turnovers for the membrane-incorporated catalyst and the QDs, respectively.
