Synthesis and Characterization of Inorganic-Organic Derivatives of Layered Perovskite-like Niobate HSrNbO with -Amines and -Alcohols.

A protonated and hydrated Dion-Jacobson-phase HSrNbO∙yHO was used to prepare two series of inorganic-organic derivatives containing non-covalently intercalated -alkylamines and covalently grafted -alkoxy groups of different lengths, as they are promising hybrid materials for photocatalytic applications. Preparation of the derivatives was carried out both under the conditions of standard laboratory synthesis and by solvothermal methods. For all the hybrid compounds synthesized structure, quantitative composition, a type of bonding between inorganic and organic parts as well as light absorption range were discussed using powder XRD, Raman, IR and NMR spectroscopy, TG, elemental CHN analysis, and DRS.
