Applications of Silver on Alumina

Environmental Applications

Selective Catalytic Reduction (SCR) of NOx:

Effective for reducing nitrogen oxides (NOx) in exhaust gases from diesel engines and industrial processes, especially in oxygen-rich environments.

Volatile Organic Compound (VOC) Oxidation:

Degrades VOCs into less harmful substances, aiding in air purification.

2. Chemical Industry

Ethylene Oxide Production:

Used as a catalyst in the selective oxidation of ethylene to produce ethylene oxide, a key intermediate for producing ethylene glycol and other chemicals.

Alcohol and Hydrocarbon Oxidation:

Facilitates partial or complete oxidation of alcohols and hydrocarbons, critical in organic synthesis.

3. Pharmaceutical and Fine Chemicals

Selective Oxidation Reactions:

Used in the synthesis of fine chemicals and pharmaceutical intermediates, where high selectivity is required.

4. Fuel and Energy Sector

Hydrogen Production:

Supports reforming reactions to produce hydrogen from hydrocarbons or alcohols.

Fuel Cells:

Acts as a catalyst in fuel cell systems to enhance efficiency.

5. Water and Wastewater Treatment

Decomposition of Pollutants:

Catalyzes the breakdown of organic pollutants and residual contaminants in water.

Antimicrobial Activity:

Silver ions released from the catalyst exhibit antimicrobial properties, aiding in disinfection.

6. Sensor Technology

Gas Sensors:

Enhances sensitivity in detecting gases such as ammonia (NH₃), NOx, or hydrocarbons in air monitoring systems.

7. Renewable Energy and Green Chemistry

Photocatalysis:

Works in tandem with light to drive oxidation-reduction reactions for clean energy production and environmental applications.

Silver on alumina’s efficiency and stability make it an essential catalyst in industrial, environmental, and emerging technologies.
