Cu–Pd/Zeolite as Efficient Thermo‐Catalyst to Oxidize Low‐Concentration Methane
ChemCatChem, EarlyView.Methane’s low concentration belies its warming impact and challenging catalytic abatement. We synthesise highly dispersed Cu–Pd on low‑cost mordenite (MOR) to oxidise 200 ppm CH4, achieving 90% conversion at 358 °C and stable operation for 100 h. Copper lowers Pd usage (0.10 wt% Pd) via synergistic dispersion and thermal stabilisation, surpassing Pd ...
