The combined advantages of layered double‐hydroxide catalysts and rare‐earth compounds are found in the layered rare‐earth hydroxides [R 4 (OH) 10 (H 2 O) 4 ] n A n (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.
