Heterogeneous catalysis — is a chemistry term which describes catalysis where the catalyst is in a different phase (ie. solid, liquid and gas, but also oil and water) to the reactants. Heterogeneous catalysts provide a surface for the chemical reaction to take place on.… … Wikipedia
Heterogeneous — is an adjective used to describe an object or system consisting of multiple items having a large number of structural variations. It is the opposite of homogeneous , which means that an object or system consists of multiple identical items.… … Wikipedia
heterogeneous reaction — ▪ chemical reaction any of a class of chemical reactions in which the reactants are components of two or more phases (solid and gas, solid and liquid, two immiscible liquids) or in which one or more reactants undergo chemical change at an… … Universalium
heterogeneous catalysis — noun Catalysis in which the catalyst is present in a separate phase; normally the catalyst is a solid and the reactants are gas or liquid; it proceeds by the reaction of chemisorbed complexes … Wiktionary

Phase transfer catalyst — A phase transfer catalyst or PTC in chemistry is a catalyst which facilitates the migration of a reactant in a heterogeneous system from one phase into another phase where reaction can take place. Ionic reactants are often soluble in an aqueous… … Wikipedia
Post-metallocene catalyst — A post metallocene catalyst is a kind of catalyst for olefin polymerization. Post metallocene refers to the generation of catalysts following Kaminsky catalysts, which are metallocene catalysts discovered in 1980 by Walter Kaminsky, and have been … Wikipedia
Homogeneous and heterogeneous reactions — Homogeneous reactions are chemical reactions in which the reactants are in the same phase, while heterogeneous reactions have reactants in two or more phases. Reactions that take place on the surface of a catalyst of a different phase are also… … Wikipedia
Nanomaterial based catalyst — Nanomaterial based catalysts are usually heterogeneous catalysts broken up into nanoparticles in order to speed up the catalytic process. The extremely small size of the particles maximizes the surface area exposed to the reactant, allowing more… … Wikipedia
