Catalysts based on Cu or Co zeolite beta are active catalysts for the TCE oxidation.

The way Cu/Co is added to the zeolite plays a significant role on the activity.

Cu-exchanged zeolite beta was more active than H-zeolites catalyst.

Strong Brönsted acid sites and metals with redox properties catalyze TCE oxidation.

An adequate combination of these properties is necessary to have active catalysts.
