The common catalysts are platinum, rhodium and palladium.

That catalyst is known as chlorophyl.
Catalytic converters are but one part of a comprehensive pollution control system on a vehicle. Catalytic converters are 100% effective in achieving the pollution reductions demanded of them by the auto manufacturers. The converter is the last step in cleaning exhaust before comes out the tailpipe and into the air. A catalytic converter contains a catalyst. A catalyst acts as a chemically neutral facilitator of molecular reaction between other chemicals, without the reacting chemicals or the reaction byproducts effecting the catalyst itself. The whole purpose of the catalytic converter is to convert exhaust gas pollutants to environmental friendly chemicals and compounds that exit through the tail pipe at the rear of your vehicle. In a typical gasoline-powered passenger car, the target exhaust gases CO2 and water. Ever see water dripping from a car's exhaust pipe? That's not a defect. Dripping water from an exhaust pipe means that the car's pollution control system - and its catalytic converter - are working properly.

enzymes acts as biological catalyst.
Enzyme
Oxygen acts as a reactant.
All Enzyme are proteins enzymes act as catalyst
First of all 'catalist ' is spelled as 'CATALYST'. Note the 'Y' in place of 'i'. A protein that acts as an orgsanic catalyst is an ENZYME.
