MOF-coated catalyst converts CO₂ to CO nearly five times faster under ultrasonic vibration

Researchers at the University of Osaka have developed a catalyst that uses mechanical vibration to convert carbon dioxide (CO2) into carbon monoxide (CO), an important chemical feedstock. The catalyst consists of barium titanate (BaTiO3) coated with a metal-organic framework (MOF)—a porous material that captures and concentrates CO2 near the catalyst surface—and incorporates isolated copper (Cu) atoms as reaction sites.
