Artificial photosynthesis aims to produce fuels and chemicals from simple building blocks (i.e. water and carbon dioxide) using sunlight as energy source. Achieving effective photocatalytic systems necessitates a comprehensive understanding of the underlying mechanisms and factors that control the reactivity. This review underscores the growing interest in utilizing bioinspired artificial vesicles to develop compartmentalized photocatalytic systems. Herein, we summarize different scaffolds employed to develop artificial vesicles, and discuss recent examples where such systems are used to study pivotal processes of artificial photosynthesis, including light harvesting, charge transfer, and fuel production. These systems offer valuable lessons regarding the appropriate choice of membrane scaffolds, reaction partners and spatial arrangement to enhance photocatalytic activity, selectivity and efficiency. These studies highlight the pivotal role of the membrane to increase the stability of the immobilized reaction partners, generate a suitable local environment, and force proximity between electron donor and acceptor molecules (or catalysts and photosensitizers) to increase electron transfer rates. Overall, these findings pave the way for further development of bioinspired photocatalytic systems for compartmentalized artificial photosynthesis.

La fotosíntesis artificial tiene como objetivo imitar la fotosíntesis natural al almacenar energía solar en los enlaces químicos de combustibles y productos químicos, utilizando bloques de construcción simples y fácilmente disponibles como el agua y el dióxido de carbono. El desarrollo de sistemas fotocatalíticos eficientes y robustos para la fotosíntesis artificial requiere una comprensión exhaustiva de los mecanismos catalíticos subyacentes y de los factores que rigen la actividad y selectividad catalítica. Esta revisión enfatiza el creciente interés en el uso de vesículas artificiales bioinspiradas para compartimentar las transformaciones relacionadas con la fotosíntesis artificial. Aquí, resumimos los diferentes andamios utilizados para desarrollar vesículas artificiales bioinspiradas y exploramos ejemplos recientes en los que esos sistemas se han utilizado para estudiar procesos fotocatalíticos.
