Topotactic Oxidation of TiGaPO-1,a Pyridine-Templated Titanium Gallophosphate with a New Octahedral-Tetrahedral 3-D Framework Structure Containing Ti~III/Ti~(IV)

摘要

The first 3-D open-framework TiGaPO complex,constructed from Ti~IIIO_6,Ti~IVO_6,GaO_4,and PO_4 polyhedra,contains pyridinium cations in a 1-D pore network and can be oxidized in air at 543 K with retention of the original framework structure.Microporous materials attract tremendous research interest because of their applications as molecular sieves,ion exchangers,and catalysts in a range of technologically and commercially important processes.
