New CeO2–TiO2, WO3–TiO2 and WO3–CeO2–TiO2 mesoporous aerogel catalysts for the low temperature selective catalytic reduction of NO by NH3

New mesoporous and well-structured aerogel catalysts (CeO 2 –TiO 2 , WO 3 –TiO 2 and WO 3 –CeO 2 –TiO 2 ) were elaborated via the sol–gel method, characterized by means of various techniques (XRD; N 2 -Physisorption at 77 K; NH 3 -TPD; H 2 -TPR; DRUV–Vis spectroscopy) and evaluated in the selective...
