One-step CO₂ system triples capture, ditches silver for zinc, and turns emissions into industrial fuel feedstock

Every year, power plants and factories release billions of tons of carbon dioxide (CO₂) into the atmosphere. Methods exist to capture that CO₂ using chemical solutions and, separately, to convert pure CO₂ into useful fuels and chemicals. But doing both steps at once, in a cost-efficient and scalable way, has been difficult.
