"Artificial Photosynthesis: Key to Space Colonization?"

Artificial photosynthesis, using semiconductor materials and metallic catalysts, could be crucial for space exploration and colonization by efficiently producing oxygen and recycling carbon dioxide. These devices could reduce reliance on heavy and unreliable systems currently used on the International Space Station. The devices could operate at room temperature at pressures found on Mars and the Moon, and could be used directly in habitats using water as the main resource. The insights gained from designing and fabricating these devices could also help meet the green energy challenge on Earth.
