Shape-controlled synthesis of ruthenium nanocrystals and their catalytic applications

The catalytic properties of ruthenium (Ru) are fairly well known. Nevertheless its shape-controlled synthesis (especially as compared to other noble metals) is still elusive. In this review, we present recent advances in the synthesis of Ru nanomaterials, in particular, spherical nanoparticles, one dimensional nanostructures, nanoplates and hollow structures, as well as other examples. In addition, the catalytic applications of Ru materials are selectively surveyed. Finally, the challenges and perspectives on the controlled synthesis of Ru-based nanomaterials and their catalytic applications are described.
