Abstract

This study aimed to provide insight into how ultrasonic treatment affects microstructure, electrical properties, and physicochemical characteristics. Sonochemical ultrasound synthesis offers a distinct advantage over traditional methods by creating precise reaction conditions through acoustic cavitation. This process induces high temperatures and pressures in a liquid environment, facilitating the synthesis of materials with specific structures, sizes, and properties. In response to this capability, we developed low-cost M₂P₂O₇ (M = Co, Mn) phosphate materials known as CoP and MnP. The samples were analysed for their crystalline structure, surface morphology, and elemental composition via X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM).

The electrochemical performance of the samples was assessed via complex impedance spectroscopy methods. The results demonstrate that the samples exhibit excellent semiconductor behavior, indicating their potential for use in energy and catalytic applications.

超声辅助声化学合成 M2P2O7（M = Co、Mn）纳米材料：增强的结构形态和离子传导机制

本研究旨在深入探讨超声处理如何影响微观结构、电性能和理化特性。与传统方法相比，超声化学合成法通过声空化创造精确的反应条件，具有明显的优势。这一过程可在液体环境中产生高温高压，从而促进具有特定结构、尺寸和特性的材料的合成。针对这种能力，我们开发了低成本的 M2P2O7（M = Co、Mn）磷酸盐材料，即 CoP 和 MnP。我们通过 X 射线衍射 (XRD)、透射电子显微镜 (TEM) 和扫描电子显微镜 (SEM) 分析了样品的晶体结构、表面形态和元素组成。结果表明，这些样品表现出优异的半导体性能，显示了它们在能源和催化应用方面的潜力。

期刊介绍： This interdisciplinary journal is devoted to the physics, chemistry and materials science of diffusion, mass transport, and reactivity of solids. The major part of each issue is devoted to articles on: (i) physics and chemistry of defects in solids; (ii) reactions in and on solids, e.g. intercalation, corrosion, oxidation, sintering; (iii) ion transport measurements, mechanisms and theory; (iv) solid state electrochemistry; (v) ionically-electronically mixed conducting solids. Related technological applications are also included, provided their characteristics are interpreted in terms of the basic solid state properties. Review papers and relevant symposium proceedings are welcome.
