Catalysts for sanitary air cleaning from ozone

The results of the kinetic study of ozone decomposition over carbon fibrous materials and metal complex compounds (CuCl2) supported on them at ozone concentrations in the 3.1 x 10(-8)-3.1 x 10(-5) mol/l range are presented. Ozone decomposition occurs mainly in a catalytic way with the steady-state regime attainment depending on CFM physico-chemical as well as structural characteristics and macrokinetic factors of the process. Copper (II) catalyzes decomposition of ozone microconcentrations only. The data obtained can be a base for the development of sanitary air cleaning units and respirators (protective gas-masks).
