What are Some Applications of Catalysis in Air Pollution Control?
Catalysis is pivotal in controlling air pollution through various technologies:
Selective Catalytic Reduction (SCR): This process uses a catalyst to convert nitrogen oxides (NOx) in exhaust gases into nitrogen and water, significantly reducing air pollution from industrial sources. Photocatalysis: This involves the use of light-activated catalysts, such as titanium dioxide, to break down airborne pollutants and volatile organic compounds (VOCs). Catalytic Converters: Installed in vehicles, these devices use platinum, palladium, and rhodium catalysts to convert harmful gases like carbon monoxide, hydrocarbons, and NOx into less harmful substances.
