Platinum, Palladium, Rhodium, etc.
no
Not always, it can also be an element
yes.. No. That's no. Heat controls the rate of reaction, but a catalyst is defined as a *chemical agent* (element/ compound) that alters the rate of reaction.
They have empty d orbitals.So they can adsorb electrons from substrate and act as catalysts
This substance is called a catalyst.
Yes, it is a chemical catalyst.
Not always, it can also be an element
An important example is platinum.
yttrium
The elements in the middle section of the Periodic Table are the transition in the Haber process; Nickel is a catalyst used in the manufacture of margarine.
Stimulants - but more probably catalyst.
I believe you are looking for the term "accelerant." A catalyst.

Silver is not an element found in catalytic converters. You can find platinum, which serves as a catalyst.
base on what type of catalyst you are yalking about but all catalyst are made up of element which bonded together to form a funtional compound which are inert to the reaction but provided a alternative route in the particular reaction.
Catalytic converters are made of platinum-iridium catalyst or a ceramic monolith
They have empty d orbitals.So they can adsorb electrons from substrate and act as catalysts
If you mean something else, like- What can speed up a chemical reaction, that would be a catalyst. Or, you could say heat, though that is not an element.
