Abstract

. Techno-economic analysis demonstrates cost competitiveness against biological counterparts. When applied to plant cultivation, this artificial photosynthesis system boosts solar-to-biomass conversion efficiency by 3.5-fold compared to natural photosynthesis. By unifying solar energy harvesting, waste nitrate reduction, and carbon sequestration, our work provides a scalable blueprint for a closed-loop agrochemical ecosystem and advanced catalyst design for intermittent renewable-powered electrosynthesis.
