In the previous study, our group reported artificial photosynthesis system consisted of earth abundant elements. In this study, we report carbon support effect on the catalytic activity of Mn complex catalyst for CO2 reduction to CO. Carbon nanohorns were best carbon support to enhance catalytic activity. Additionally, we succeeded in the CO production using artificial photosynthesis system consisted of earth abundant elements with solar-to-CO conversion efficiency of 3.3%.
