Acting at the gas-liquid-solid interface to permit carbon dioxide and water to react, the catalyst achieves 80% efficiency

A highly-efficient cobalt terpyridine-based catalyst has been developed that can convert carbon dioxide into methane. The catalyst operates at the gas-liquid-solid interface improving efficiency, offering a way to turn a waste product into a fuel.

Researchers have long sought efficient ways to convert carbon dioxide into methane to combat the climate crisis. Yet, creating the right chemical conditions has proven tricky due to the different physical states of carbon dioxide and water, as well as water’s tendency to undergo competing side reactions.
