Conjugated Molecules Based Multi-Component Artificial Photosynthesis System for Producing Multi-Objective Products

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. The liposomes-based artificial photosynthetic nanocapsules are designed through one-pot methods, containing photocatalysis, chemical catalysis, and biocatalytic modules. It couples different modules, simulating the photosynthesis, thereby achieving the controllable output of oxygen, adenosine triphosphate, nicotinamide adenine dinucleotide, and methanol with an improved efficiency of 231%, 30%, 86%, and 37%, respectively.image
