NH4[Co1−yNiyPO4]·H2O (0 ≤ y ≤ 1) single crystals were fired to prepare Co2−xNixP2O7 0 ≤ x ≤ 2 solid solutions between 800 and 1200°C. The structure of these solid solutions is α‐M2P2O7 (M = Co, Ni). The contraction of the unit cell with increasing x confirmed the formation of these solid solutions. The UV–vis–NIR spectra of these solid solutions were consistent with Co(II) and Ni(II) ions in the two different crystallographic sites (octahedral site and square pyramidal site) in the α‐M2P2O7 structure. Due to their thermal stability, Co2−xNixP2O7 (0 ≤ x ≤ 2) solid solutions with α‐M2P2O7 structure can be used as a blue, green, brown or yellow ceramic pigment.

A significant challenge in the realm of asynchronous capacitors is the development of innovative electrode materials with improved electrochemical behaviour and increased cycles. In this article, a new method is proposed for the facile synthesis of bi metal pyrophosphate anchored on polypyrrole (CoNiP2O7/NF@PPy) utilizing the hydrothermal and polymerization procedures. Cobalt nickel pyrophosphate nanoarrays are created, and they are successfully used as an electrode material for supercapacitors. The novelty of this work, a novel electrode of binder free mixed metal pyrophosphate (CoNiP2O7) composited to conducting polymer of polypyrrole is developed. Then, the prepared CoNiP2O7/NF CoNiP2O7/NF@PPy electrodes capacitive and diffusive mechanism discussed by using Trassati method. In electrochemical experiments, the CoNiP2O7/NF@PPy composite showed considerably enhanced specific capacity (1202 mAhg−1), which is much greater than that of pure CoNiP2O7/NF (819 mAhg−1). Additionally, the hybrid supercapacitor (CoNiP2O7/NF@PPy//AC) device manufactured had the highest energy density of 94.6 Wh kg−1. These findings indicate that this composite is a promising option for electrochemical capacitors.
