| الوصف: | Phosphate tungsten bronzes (PWBs) constantly attract a lot of attention due to their interesting chemical, electrical, optical, and mechanical features [1]. Heteropoly acid hydrate H3PW12O40×29H2O (PWA) was obtained by dissolving Na2WO4×2H2O in a H3PO4-HCl mixture and by extracting the precipitate with ether at room temperature. The dehydration process of H3PW12O40×29H2O (PWA) to H3PW12O40×6H2O (6- PWA) is done by heating of PWA in a kiln at 80 °C. An aqueous solution of H3PW12O40×6H2O is then mixed with an aqueous solution of CoCl2×6H2O, gently heated to initiate the crystallization process, and left overnight to complete crystallization. The obtained with (CoHPW12O40×nH2O, CoPWA) is then heated in a furnace, from room temperature to 600 °C, during which cobalt phosphate tungsten bronze crystals are formed. Obtained CoPWB was further characterized by FTIR, XRPD and SEM-EDS methods which confirmed the formation of the desired structure. In this work, cobalt phosphate tungsten bronze was synthesized and characterized for the first time in order to obtain more information about its structure, chemical characteristics and potential practical application. A potential practical application of Co-PWB is in its incorporation into aqueous lithium-ion batteries and catalysts in the Briggs Rauscher reaction. |
