"Sunlight-Powered Process Removes CO2 from the Atmosphere"

Researchers at ETH Zurich have developed a novel carbon dioxide removal process that utilizes sunlight to capture and release carbon dioxide from the atmosphere. The process involves using photoacid molecules that react to light to influence the acidity of a liquid, allowing for the capture and release of carbon dioxide. This new method eliminates the need for energy-intensive temperature or pressure differences, potentially offering a more energy-efficient and cost-effective solution for carbon capture. While still in the early stages, this research could have significant implications for mitigating climate change by providing a way to remove carbon dioxide from the air using sunlight.
