Anisotropic Growth of TitanIa onto Various Gold Nanostructures: Synthesis, Theoretical Understanding, and Optimization for Catalysis

摘要

To incorporate new functionalities, various oxide-based materials are being combined with metal nanoparticles to form metal-oxide hybrid nanostructures for a wide range of promising applications, including labeling/sensing, cataly-sis, and surface-enhanced Raman scattering. Over the years, many efforts have been devoted to the growth of inert protective SiO2 shells onto metal cores to form concentric core-shell nanostructures. It is of great interest to couple metal nanoparticles with other oxides (e.g., TiO2, CeO2, Fe3O4) to form non-centrosymmetric metal-oxide nanostructures with combined optical, catalytic, and magnetic properties.
