most of the metals (either in the form of native metals or as their compounds) are known to act as catalysts for one reaction or the other.
Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
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.
Some examples of platinum include platinum jewelry, platinum catalysts used in chemical reactions, and platinum electrodes in certain electronic devices. Platinum is also used in the automotive industry for catalytic converters.
Other chemicals that can act as catalysts for the luminol reaction include hemoglobin and horseradish peroxidase. These catalysts can enhance the chemiluminescence produced when luminol reacts with hydrogen peroxide in the presence of an appropriate metal ion.
Examples of enzyme catalysts include amylase (digests carbohydrates), protease (digests proteins), and lipase (digests fats). Each of these enzymes helps to speed up specific chemical reactions in the body.

Substances like salt, which do not speed up chemical reactions, are non-examples of catalysts. In addition, compounds that hinder or slow down reactions instead of accelerating them are also non-examples of catalysts. Materials like water or inert gases that do not participate in the reaction are other examples of non-catalysts.

Inorganic catalysts are substances like metals or metal oxides that speed up chemical reactions without being consumed in the process. Examples include platinum, iron, and nickel. They work by providing an alternative pathway for the reaction to occur, lowering the activation energy needed for the reaction to proceed. This allows the reaction to happen faster and more efficiently.
