Synthesis, properties and applications of noble metal iridium nanomaterials

Noble metal iridium nanostructures have been gaining significant research interest due to their unique optical, electronic and catalytic properties for promising applications, which critically depend on their size, shape/morphology and composition. As such, various synthetic strategies have been exploited to achieve these targeted properties for improved applications. This review focuses on the recent advances in the preparation, properties (e.g. catalytic activity, surface-enhanced Raman scattering and luminescence properties) and applications (primarily for catalysis) of Ir nanomaterials. It will also deliberate potential challenges and opportunities in preparing novel iridium nanomaterials and exploring their potential properties and applications.
