A new method developed by a team of Waseda University scientists led byProfessor Yasushi Sekinemay contribute to reducing the use of fossil fuels and help prevent global warming in the long-run.

The conversion of bcゲーム退会 to valuable chemicals such as methane has drawn great attention for use in supporting carbon capture and utilization. Especially, methane can be used not only as fuel but also as a hydrogen carrier, transporting town gas to existing infrastructure. For instance, some plants in Germany have already been launched based on the Power to Gas concept, which allows energy from electricity to be stored and transported in the form of compressed gas.

"To recycle bcゲーム退会 into methane, an established industrial method involves the reaction of hydrogen and bcゲーム退会 using a ruthenium-based catalyst at temperatures of 300 to 400 degrees Celsius, but this method limited how much and when methane could be produced since it requires such high temperature," Sekine says. "Additionally, operation at low temperatures was demonstrated to be favorable to improve bcゲーム退会 conversion and increase the amount of methane produced."

In this newly-developed method reported inChemistry Letters, bcゲーム退会 can be converted into methane more efficiently and quickly in the 100 degrees Celsius range.

"This method involves a reaction of nanoparticles called cerium oxide with bcゲーム退会 in presence of ruthenium catalyst with an electric field," explains Sekine. "The results show that the catalyst exhibited high and stable catalytic activity for converting bcゲーム退会 to methane through hydrogenation with the electric field."

With this novel method, methane could be produced from bcゲーム退会 collected from the atmosphere, possibly enabling an unlimited amount of methane production by recycling bcゲーム退会 from the atmosphere released from factories into valuable energy resources.
