Optimizing CuO on 3D Ordered Macroporous CeO2 for CO Oxidation in Rich Hydrogen
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT CO preferential oxidation (CO‐PROX) in rich H2 is considered a feasible strategy to solve CO poisoning for fuel cells, but obtaining good activity at low temperatures is still a challenge. Herein, three‐dimensional ordered macroporous (3DOM) CuO/CeO2 catalysts were fabricated by a templating approach, with the metal–support interaction (MSI ...
