Hydrous ruthenium oxide triggers template-free and spontaneous growth of metal nanostructures.

ABSTRACT: Intrinsically conductive ruthenium oxide is an excellent material for energy storage and conversion. Herein, we present hydrous RuO₂ (H-RuO₂) as a potent reducing agent to achieve spontaneous growth of multiple noble metals at room temperature. Self-assembled gold and platinum, comprising small-sized nanoparticles, are generated on the surface of H-RuO₂ without the need for additional templates. Structural analysis reveals that the disordered structure and the presence of oxygen vacancies trigger interfacial redox reactions between H-RuO₂ and oxidative metal salts. The resulting integrated nanostructures, consisting of a metal oxide and different metals (H-RuO₂@metal), are subsequently used to treat inflammatory bowel diseases. In addi
