Abstract
Catalizzatore per ridurre ossidi di azoto nei gas di combustione comprendente composti di titanio e vanadio in lamelle di singoli cristalli separati fra loro, aventi tutti la stessa dimensione lineare compresa fra 50 A e 200 A e privi di porosità interna, il catalizzatore essendo ottenuto irradiando con un laser a C02 composti metallorganici di titanio e vanadio insieme con un getto di un gas sensibilizzatore a banda di assorbimento nella zona spettrale fra 940 e 1000 cm alla -1.
