Abstract

The development of artificial photosynthesis systems that mimics natural photosynthesis can help address the issue of energy scarcity by efficiently utilizing solar energy. Here, it presents liposomes-based artificial photosynthetic nanocapsules (PSNC) integrating photocatalytic, chemical catalytic, and biocatalytic systems through one-pot method. The PSNC contains 5,10,15,20-tetra(4-pyridyl) cobalt-porphyrin, tridipyridyl-ruthenium nitrate, oligo-pphenyl-ethylene-rhodium complex, and creatine kinase, efficiently generating oxygen, nicotinamide adenine dinucleotide (NADH), and adenosine triphosphate with remarkable enhancements of 231%, 30%, and 86%, compared with that of molecules mixing in aqueous solution. Additionally, the versatile PSNC enables simulation of light-independent reactions, achieving a controllable output of various target products. The regenerated NADH within PSNC further facilitates alcohol dehydrogenase, yielding methanol with a notable efficiency improvement of 37%. This work introduces a promising platform for sustainable solar energy conversion and the simultaneous synthesis of multiple valuable products in an ingenious and straightforward way.
