Dispersed Complex Phosphates as Tailored Acid Catalysts: Synthesis and Properties

  • Published:
MRS Online Proceedings Library Aims and scope

Abstract

The relationship between the chemical composition, bulk real structure, surface properties and catalytic activity of dispersed complex framework zirconium phosphates with a NASICON-type structure is considered. For both crystalline and amorphous samples, a model of their bulk structure is suggested. The Lewis and Bröensted acidity was shown to vary broadly and be dependent upon the composition and preparation procedure, which is important for catalysts of hydro-carbons activation. Selective catalytic reduction of NOx by methane in excess oxygen appears to be one of the application areas for these systems.
