Abstract

1494484 Catalytic coatings INST. CIEZKIEJ SYNTEZY ORGANICZNEJ "BLACHOWNIA" 20 Nov 1974 [28 Nov 1973] 50231/74 Headings B1E and B2E Catalytic material e.g. for oxidation of noxious gases is prepared by (i) forming a non-gel aqueous colloidal dispersion of aluminium hydroxide containing from 0.05 to 10 per cent weight of solid material (calculated as alumina) and introducing thereinto a noble metal or noble metal compound of group VIII of the Periodic Table, and (ii) applying a coating of the resulting composition to carrier material. The noble metal component may be colloidal platinum, colloidal platinum compounds, chloroplatinic acid, teramino platinic chloride, ammonium chloroplatinate or palladium salts. From 0.01 to 10% wt. (based on alumina) of a compound of Re, W, Mo, Cr, V, Ti, Zr, Nb or Cd may be added to modify the properties of the composition and a stabilizer for the colloidal dispersion may be added, e.g. arabic gum, lysalbinic acids, gelatine, starch, silica or alkaline earth compounds. The composition may further contain a compound to improve adhesion to the carrier, e.g. one containing chloride, nitrate, fluoride, borate or phosphate ions. The carrier may be a metal or metal alloy or an oxide. The examples describe the application to metallic or oxidic carriers of compositions comprising aluminium hydroxide and (i) palladium chloride, platinum sulphide and arabic gum, (ii) chloroplatinic acid, cadmium chloride and chromium chloride; (iii) Keller's complexing agent, ammonium perhenate and niobium pentafluoride: (iv) iridium chloride, ammonium chloroplatinate and gelatine; (v) colloidal platinum, silica and calcium nitrate; and (vi) chloroplatinic acid, zirconium nitrate and silica.
