Characterization of Co/sulfated zirconia catalysts for selective reduction of NO by methane
In this study, Co based catalysts (0.5–5 wt% Co) supported on sulfated zirconia were prepared for NO selective reduction by methane. The effect of Co loading on the catalyst structure, the catalytic activity and stability, as well as the deactivation rate by 6 vol% water in the feed are reported. Th...
