A catalyst for reducing nitrogen oxides in combustion gases and a method for its production.

摘要

A catalyst for reducing oxides of nitrogen in combustion gases comprising compounds of titanium and vanadium in particles of single monodispersed crystals, all having the same linear dimension between 50 ANGSTROM and 200 ANGSTROM and lacking internal porosity, the catalyst being obtained irradiating with a CO2 laser beam metallo-organic compounds of titanium and vanadium together with a jet of a sensitizer gas at an absorption band in the spectral zone between 940 and 1,000 cm<-><1>.
