Acid properties of Ti-Zr phosphates pillared with silica and silica-alumina oligomers have been studied by following the adsorption-desorption of several probe molecules with different acid strengths (NH 3, pyridine and isopropanol). Samples showed s

The acidic character of the hydration water in NbOPO{sub 4} {center_dot} 2H{sub 2}O permits the exchange of protons for Li{sup +} ions. The lithium phase annealed at 773 K presents a slightly distorted lattice with respect to the niobium phosphate ne

The laminar compounds VOPO4.2H2O and VOAsO4.3H2O interact with primary and tertiary amides to produce either dehydration or intercalation reactions, or sometimes both. The tetragonal structure of the starting solids was preserved, and in some cases,

The laminar compound HUO 2 PO 4 ·4H 2 O (HUP) interacts with piperidine, hydrazine, pyridine, pyrazine and (dimethylamino-methyl)ferrocene to produce intercalation reactions. The intercalate materials exhibit a layered structure derived from the sta
