Abstract

The hierarchical Ni₃(PO₄)₂/Co₃(PO₄)₂ nanocomposites were fabricated by one step hydrothermal technique via immersing Ni²⁺ and Co²⁺ with PO₄^3-. Varing the cations, e.g., Na₂HPO₄, K₂HPO₄ and (NH₄)₂HPO₄, the morphological changes of leaf, rod and platelet morphology of prepared nanocomposites were observed due to the Kirkendall effect modifying the nanomaterial structure via interdiffusion of transition metal atoms with phosphate ions source. The developed bimental phosphates displayed enhanced activity in dye degradation and supercapacitive performance. The Ni₃(PO₄)₂/Co₃(PO₄)₂ composite as an effective catalyst was applied for degradation of Rhodamine B by PMS activation. The maximum dye degradation efficiency was about 97% after 40 min. The prepared composite effectively produced sulfate radicals even after fifth cycle. In addition, the cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance analysis were investigated in 1 M Na₂SO₄ neutral electrolyte. The electrochemical investigations clearly indicated the Ni₃(PO₄)₂/Co₃(PO₄)₂ composites enhanced super capacitive performance with good stability nature. Hence, the bi-functional activities of Ni₃(PO₄)₂/Co₃(PO₄)₂ have the potential candidate to the water purification and energy storage applications.
