Аннотация: <jats:p> The fusion of biological pathways with synthetic inorganic materials provides inspiring blueprints for sustainable fuel production1-4. Here, we use a top-down cellular engineering strategy to develop a new semi-artificial photosynthesis paradigm for carbon dioxide reduction by wrapping Halobacterium purple membrane-derivedПоказать полностьюvesicles over Pd-deposited hollow porous TiO2 nanoparticles. In this biohybrid, the membrane protein, bacteriorhodopsin, not only retains its native biological function of pumping protons but also acts as a photosensitizer that injects light-excited electrons into the conduction band of TiO2. Thus, the photoinduced electrons and protons accumulated within the confined architecture act in concert to reduce CO2 emissions on the Pd cocatalyst through proton-coupled multielectron transfer processes. This study provides an alternative toolkit for developing robust semi-artificial photosynthetic systems for solar energy conversion.5</jats:p> <jats:p>1. Balasubramanian, S.; Wang, P.; Schaller, R.
