Description
High-entropy (oxy)(hydr)oxides have been recently proposed as promising materials for environmental remediation and electrocatalytic applications due to their ability to integrate multiple cations into a single structure. This compositional complexity generates synergistic effects that outperform those of single-metal systems. However, current synthesis methods largely overlook the chemical and hydrolysis behavior of particular metals, introducing uncertainties to the final functional performance of these materials. This study focuses on the existing synthesis strategies, emphasizing the chemistry of single metals (Fe, Ni, Co) constituting typical high-entropy (oxy)(hydr)oxides. Special attention is given to the heterogeneous nucleation and the influence of substrate properties, including chemical composition, crystal structure, and functional groups, on the nucleation, growth, and particle morphology, providing fundamental insights into the nucleation behavior and paving the way toward the rational design of high-entropy (oxy)(hydr)oxides as efficient and sustainable solutions for modern societies.
