Composition Of Catalyst
Jun 26, 2017

Most catalysts have three types of distinguishable components: active components, supports, and cocatalyst.

Active component


The active component is the main component of the catalyst, sometimes consisting of a substance, sometimes consisting of a variety of substances


Active ingredient classification:

category  Electrical conductivity (reaction type)Examples of catalytic reactions
MetalConductor (oxidation reaction, reduction reaction)

Selective hydrogenation; selective hydrogenolysis; selective oxidation

Transition metal oxides and sulfidesSemiconductor (redox)

Selective hydrogenation and dehydrogenation; hydrogenolysis; oxidation

Non transition element oxideInsulator (carbon ion reaction, acid-base reaction)

Polymerization and isomerization; cracking; dehydration
