METHOD FOR PRODUCTION OF PHOTOCATALYTICALLY ACTIVE TITANIUM OXIDE FOR UV AND VISIBLE REGION O LIGHT SPECTRUM

摘要

The method for production of photocatalytically active titanium oxide consisting in hydrolyses of titanyl sulphate by thioacetamide, urea or hydroxymethylamine in a water environment at temperatures of 40 - 100°C and drying of the acquired product at temperatures up to 120°C; the dried product is annealed up to a temperature of l,000°C in an oxygen atmosphere. During hydrolysis, dopants with soluble salts of components selected from groups Sc, Zn, Y, Zr, Nb, Cd, Al, Ta and lanthanides can be used.
