dc.descriptionAbstract: ReO3 were prepared by thermal treatment of the macromolecular Chitosan·(ReCl3)X and PSP-4-PVP·(ReCl3)X precursors. The plasmon band in the visible region for the as obtained ReO3 from their visible spectra was observed at λmax of 640 nm. The nature of the polymeric precursor is acting as a solid state template and influences the size and morphology of the metal oxides. For the first time, the photocatalytic degradation of methylene blue using ReO3 was measured founding a moderated and high activity for ReO3 arise from Chitosan and PSP-4-PVP precursors respectively. The inclusion of ReO3 into SiO2 was performed using a combined solution of the Chitosan and PVP precursors by the sol–gel method. Subsequent pyrolysis of the solid precursors Chitosan·(ReCl3)X(SiO2)y and PSP-4-PVP·(ReCl3)X.(SiO2)y give rise to the nanocomposites ReO3//SiO2. The as obtained ReO3 nanoparticles inside SiO2 are small as 1 nm. The ReO3 nanoparticles are distributed uniformly inside the matrix of SiO2, leading to stable semi porous materials suitable for high temperature catalytic application. The composites ReO3/SiO2 exhibit a moderate photocatalytic activity toward the degradation of methylene blue and similar to that of ReO3.
