Platinum is an element, so it is "pure".
Silver is not an element found in catalytic converters. You can find platinum, which serves as a catalyst.
Catalytic converters are made of platinum-iridium catalyst or a ceramic monolith
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
Well Platinum is an element so there is really only one type. However, platinum may be used as "sheet" or finely powdered if it was going to be used as a catalyst. Alternatively, it may be used to "plate" a less expensive metal to also act as a catalyst for example in a catalytic converter.
Platinum is used in jewelry, chemotherapy, and catalytic converters.
