Abstract
PURPOSE: To prepare the titled inexpensive catalyst with a high denitration rate, by dipping a molded material which mainly consists of Ca2SiO4 into an aq. colloidal soln. of ultra-fine particles of SiO2, dipping it into an oxalie acid soln. contg. TiO2 and a cpd. which will produce V2O5 by calcination, drying it and calcinating it.
