Used as a catalyst in catalytic converters for automobiles to reduce harmful emissions by converting pollutants like carbon monoxide, nitrogen oxides, and unburned hydrocarbons into less toxic substances such as carbon dioxide, nitrogen, and water vapor. Widely employed in the petroleum industry for catalytic reforming to produce high-octane gasoline. Serves as an electrode material in fuel cells due to its high electrocatalytic activity and stability. Utilized in the production of nitric acid and silicone materials through catalytic processes. Applied in electronics for making corrosion-resistant contacts and in medical devices such as pacemakers and catheters because of its biocompatibility and durability. Also used in laboratory equipment like crucibles and electrodes where resistance to high temperatures and chemical attack is required.
