Title : Dipotassium cobalt pyrophosphate: From solid-state synthesis to the assessment of K2CoP2O7 for the oxidative degradation of methylene blue

Abstract:

Transition metal phosphates are a family of catalysts that are frequently utilized in chemical synthesis, oxygen evolution, biologic processes, and photocatalysis. Although prior research has demonstrated that combining multiple elements can significantly improve catalytic efficiency. Pyrophosphates compounds are attractive candidates for heterogeneous catalysis, especially in oxidation reactions. In the current study, Catalytic performance was assessed by testing the oxidation of the methylene blue (MB) dye with hydrogen peroxide. The data obtained demonstrated that K₂CoP₂O₇ micro-powder had extremely high catalytic activity, yielding 99% over 120 minutes at pH 11 in an alkaline environment. This catalyst has been prepared by a solid-state reaction process. The qualitative analysis of the pyrophosphate powder has been performed by means of Fourier transform infrared analysis. The crystalline phase, purity, and unit cell parameters of K₂CoP₂O₇ were analyzed using powder X-ray diffraction. The progression of the catalytic efficiency was monitored through UV-Vis absorption spectroscopy.
