Waste carbon dioxide has been converted into a potential precursor for chemicals and carbon-free fuel. The CO2 has been turned into formic acid. a catalyst made from waste lead-acid batteries. It is a colorless liquid with potential as a transportation fuel, for storing electrical energy and for enabling the petrochemical industry to cut CO2 emissions. In tests, the new method efficiently converted CO2. for more than 5,000 hours, and it might be cost-effectively scaled up for industry.
