Researchers at Osaka University have created a new catalyst that converts carbon dioxide into carbon monoxide using ultrasonic vibration. By combining barium titanate with single-atom nickel sites, the team achieved a three fold increase in CO production compared to standard materials, operating at room temperature and ambient pressure. This method uses mechanical energy to drive the chemical reaction, offering a potentially low-energy alternative to traditional high-temperature CO2 reduction. The process showed nearly 100 percent selectivity for carbon monoxide, which serves as a critical industrial feedstock.
