3D-Printed Copper Catalyst Improves Hydrogen Purification Efficiency

Researchers in Alicante have developed a 3D-printed copper catalyst designed to remove carbon monoxide from hydrogen streams. By using a complex internal geometry and combining copper with cerium oxide, the system increases the active surface area and reduces the need for expensive noble metals like platinum. This technology is particularly relevant for fuel cells, which require high purity hydrogen to prevent degradation. The use of abundant materials and 3D printing could lower the cost of hydrogen purification in industrial reforming plants and sustainable fuel production.
