Pedersen, and Wen Luo, the team has created a copper-based catalyst that achieves an remarkable 92% efficiency in converting CO₂ to acetaldehyde.

“The Wacker process has remained largely unchanged for the past 60 years. It was time for a green breakthrough,” said Koolen. The new catalyst is scalable, cost-effective, and has the potential to redefine industrial chemical production.

How It Effectively Works

The catalyst is engineered by anchoring copper clusters onto carbon supports, creating a stable and reusable material. In laboratory tests, the team demonstrated that this setup facilitates the efficient conversion of CO₂ into acetaldehyde. The process not only minimizes waste but also operates under milder conditions compared to traditional methods, reducing energy consumption and environmental impact.

Broader Implications
