New catalyst turns carbon dioxide into clean fuel source

06:08 - 03 Feb 2026

Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far longer than similar low-cost materials. Surprisingly, the improved manganese catalyst even beat many expensive precious-metal options. The discovery could help turn greenhouse gas into clean energy ingredients.
