Sentences with phrase «heterogeneous catalysis»
Heterogeneous catalysis refers to a process where a substance (called a catalyst) helps speed up a chemical reaction by interacting with the reactants. Unlike homogeneous catalysis, where the catalyst and reactants are in the same phase (like both being in a liquid), in heterogeneous catalysis, the catalyst is in a different phase (like being a solid while the reactants are in a liquid or gas). The catalyst in this process helps in making the reaction happen more quickly, without getting used up or changed itself. Full definition
«We can control the shape of the structure itself, what we call the macroscale features; and the design of the catalyst, the nanoscale features, at the same time,» said Igor Slowing, a scientist in heterogeneous catalysis at the U.S. Department of Energy's Ames Laboratory.
