Generally platinum, sometimes palladium or rhodium, rarely other metals as: Ce, Mn, Fe, Cu, Ni.
that is true
The exhaust system of your automobile is analogous.
Automobile exhaust does not directly contribute to the ozone hole. The ozone hole is primarily caused by the release of certain chemicals like chlorofluorocarbons (CFCs) and halons, which react with ozone in the stratosphere. However, automobile exhaust can indirectly affect the ozone layer by releasing nitrogen oxides, which can contribute to ozone depletion in the lower atmosphere.
A ceramic monolith catalyst substrate is a type of structure used in catalytic converters in cars. It is a honeycomb-like ceramic material with a high surface area that provides a platform for the catalytic coating, which helps convert harmful pollutants in exhaust gases into less harmful substances. The design allows for efficient contact between exhaust gases and the catalyst, improving the conversion of pollutants.
Ozone is produced when sunlight reacts with automobile exhaust emissions, particularly nitrogen oxides and volatile organic compounds. These compounds undergo a series of photochemical reactions in the presence of sunlight, leading to the formation of ozone in the atmosphere.
A catalyst is unchanged by the reaction, and remains as it was. It causes the start of the reaction, but is still there AFTER the reaction. Example- the catalytic converter on an automobile exhaust contains platinum metal. This causes a chemical reaction to take place in the exhaust gasses, but the metal remains in the converter, and is not consumed.
Exhaust tec means TORQUE EXPANSION CHAMBER it increases power and mileage of automobile
f an automobile had a 100 efficient engine would it exhaust the surroundings?
Smog.
It change the toxic gases into non toxic gases (that are exhausted)
that is true
No use for exhaust in car air conditioning
The most toxic 'metal' pollutant would be lead.Other pollutants present in the automobile exhaust are:HydrocarbonsNitrogen oxidesCarbon MonoxideCarbon Dioxide
Some exhaust systems use gaskets and some don't.

yes
