A new binary Co1/2Fe1/2(H2PO4)2·2H2O was synthesized by a simple, rapid and cost-effective method using CoCO3-Fe(c)-H3PO4system at ambient temperature. Thermal treatment of the obtained Co1/2Fe1/2(H2PO4)2·2H2O at 600 °C yielded as a binary cobalt iron cyclotetraphosphate CoFeP4O12. The FTIR and XRD...
