Carbon capture: Solar-powered option

Carbon capture: Solar-powered option - Photosynthesis is the ultimate solar-powered carbon capture technology. Plants extract carbon dioxide from the atmosphere and use sunlight to convert it into chemical energy. Now, a US team has suggested a novel reaction mechanism that can mimic photosynthesis in the binding of carbon dioxide using light energy captured by silicon nanowires. The researchers have even demonstrated proof of principle in the synthesis of two precursors of the anti-inflammatory, pain reducing drugs ibuprofen and naproxen.
