Metal oxides are ubiquitous in our daily lives because they are robust and possess versatile electrochemical properties. Despite their popularity, these materials present limitations with respect to effective large-scale implementation. Recently, there has been growing interest in creating hybrid metal oxides to tailor the morphology and properties of these materials. From this perspective, we highlight several recent developments in cross-linked hybrid metal oxides, focusing on chemical cross-linking techniques to enrich their properties. We discuss future directions of this cross-linking approach that could enable further manipulation of these materials. Chemical cross-linking represents a unique approach for creating hybrid materials with enriched properties. This method facilitates the formation of interconnected networks within the material, which can modulate its porosity, conductivity and photophysical properties. Porous morphologies are beneficial for electrochemical applications as they enable the smooth diffusion and penetration of ions, effective ion transport at material interfaces, and also offer a synergy of the properties of the constituent materials and cross-linker. This perspective article highlights the recent advances in the area of covalently cross-linked hybrid metal oxides.
