Abstract
A catalytically active porous element for promoting catalytic gas phase reactions is proposed, said element comprising a porous structural element of sintered ceramic or metallic primary particles, which are selected from fibrous and/or granular particles, a secondary structure of titania nano particles deposited on the surface of said sintered primary particles and a catalytic component deposited on the surface of the titania nano particles. Thereby porous catalytic elements for catalytic gas phase reactions which are useful not only in NOX reduction reactions but also for other catalytic gas phase reactions are provided.

A catalytically active porous element for promoting catalytic gas phase reactions, said element comprising:
- a porous structural element of sintered ceramic or metallic primary particles, which are selected from fibrous and/or granular particles, the granular primary particles having an average size of from 40 to 400 μm and the fibrous primary particles having an average diameter of from 10 to 400 μm and an average length of from 1 to 20 mm;
- a secondary structure of titania nano particles deposited on the surface of said sintered primary particles and a catalytic component deposited on the surface of the titania nano particles.
