Ziegler-Natta catalysts are heterogeneous catalysts composed of transition metals and organometallic compounds, while metallocene catalysts are homogeneous catalysts consisting of a single transition metal atom sandwiched between two cyclopentadienyl ligands. Metallocene catalysts are more precise and produce polymers with narrower molecular weight distribution compared to Ziegler-Natta catalysts.

The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst.
Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules.
Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
