Abstract (en)
[origin: GB2485546A] A catalyst comprising at least one active metal or metal oxide supported on a mixed titanium oxide/silicon oxide support is used in the conversion of ozone to oxygen at a temperature of less than 40°C in a humid atmosphere. In a further aspect, the catalyst is employed in a method of sterilisation, decontamination and/or sanitation of an enclosed environment, the method comprising producing a humidified enclosed environment; discharging ozone into the humidified environment; maintaining the ozone and water vapour pressure levels at a concentration that will achieve the required degree of decontamination; and passing the substantially decontaminated, sterilised and/or sanitised environment through the ozone depletion catalyst to reduce the concentration of ozone to a predetermined level. Preferably, the catalytically active metal is selected from iron, cobalt, nickel, silver, copper, manganese, zinc and any platinum group metal, or any oxide thereof, and most preferably is palladium. Optionally, a hydrocarbon containing a carbon-carbon double bond may be introduced into the environment to aid removal of the ozone.
