Description
Summary:Nanoparticles, being objects with high surface area are prone to agglomeration. Immobilization onto solid supports is a promising method to increase their stability and it allows for scalable industrial applications, such as metal nanoparticles adsorbed to mesoporous ceramic carriers. Tubular nanoclay – halloysite – can be an efficient solid support, enabling the fast and practical architectural (inside / outside) synthesis of stable metal nanoparticles. The obtained halloysite‐nanoparticle composites can be employed as advanced catalysts, ion‐conducting membrane modifiers, inorganic pigments, and optical markers for biomedical studies. Here, we discuss the possibilities to synthesize halloysite decorated with metal, metal chalcogenide, and carbon nanoparticles, and to use these materials in various fields, especially in catalysis and petroleum refinery. We demonstrate the strategy to synthesize halloysite clay tubes decorated with metal, metal chalcogenide, and carbon nanoparticles, and usage of these nanoarchitectures in imaging and catalysis.
