Layered Rare‐Earth Hydroxides: A Class of Pillared Crystalline Compounds for Intercalation Chemistry

Abstract

The combined advantages of layered double-hydroxide catalysts and rare-earth compounds are found in the layered rare-earth hydroxides [R4(OH)10(H2O)4]nAn (R=Y, Dy, Ho, Yb; A=organic anion). These crystalline materials (see structure) comprise rigid organic anions (balls and sticks) intercalated between inorganic layers (polyhedra). They are selective heterogeneous catalysts for hydrodesulfurization and sulfide oxidation.
