COPPER PHOSPHIDE (Cu₃P): A MODERN REVIEW OF SYNTHESIS METHODS, ELECTROCHEMICAL PROPERTIES, AND ANTICORROSION APPLICATIONS
Main Article Content
Abstract
This review presents a comparative analysis of recent advances in the synthesis technologies, crystal structure, electrochemical properties, and anticorrosion applications of copper phosphide (Cu₃P)-based materials. Twenty peer-reviewed publications were critically evaluated to compare ionothermal, hydrothermal, mechanochemical, colloidal, vapor-phase phosphorization, and pyrometallurgical synthesis routes. The influence of synthesis strategy on phase composition, morphology, electrochemical performance, and corrosion resistance was systematically assessed. The analysis demonstrates that Cu₃P-based nanostructured materials exhibit significant potential for electrochemical energy storage, electrocatalysis, and industrial corrosion protection, making them promising multifunctional materials for sustainable engineering applications.
