Sustainability,Catalytic Clothing. Helen Storey & Tony Ryan have created a dress that purifies the air in effect to reduce air pollution. Catalytic clothing gains the energy it needs to work through light. It is also designed to breakdown pollutants straight away. To see a noticeable change in the reduction of pollution, a mass amount of people would have to wear the garments because it only removes a small part of the air borne pollutants.
