Platinum and rhodium are commonly used jointly in catalytic converters. A platinum-rhodium catalyst is a reduction catalyst, which is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the nitrogen oxides (NO and NO2, together called NOx) emissions.
When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2.
For example:
2NO => N2 + O2 or 2NO2 => N2 + 2O2
Biological catalysts in organisms are called enzymes.
The work done by the catalyst is to change the mechanism of a reaction, actually the alternate way using the catalyst needs lesser energy to the same reaction without the catalyst.
Hydrogen peroxide will work.
Most of us may familiar with hotter the better but it is not necessary that catalyst prefer hot temperature. Catalyst do provide alternative path with lower activation energy, and it is not necessary like heat if the trend of overall reaction is exothermic. Many catalyst work best on limited range of temperature not too high and not too low.
This substance is called a catalyst.

it works as a catalyst
Hydrogen peroxide will work.
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.

The person that is credited with inventing the catalyst is Rayan Jafar. He created this catalyst in 1973 by having tomato sauce poured on some seeds and having them work better than they used to. He repeated this process several times.
Catalysts work by lowering the "start-up" energy of a reaction.
This substance is called a catalyst.
A catalyst is a substance that speeds up the rate of a chemical reaction.
Catalyst, biocatalyst or enzyme.
Catalyst is not a reactant.
