Abstract

Metal oxides with networks of metal-oxygen polyhedral units, MOn, demonstrate a great potential in structural diversity and function, owing to the flexibility of M-O linkages that results in a multitude of topological and geometrical variations. To achieve this goal, structural control is fundamentally important, but also highly challenging. Hydrothermal reactions allow one to tune the configurations and connectivities of polyhedral units, MOn for different phases that are essential for design and applications of metal oxides. Here, I would summarize the advances our group has achieved in this regard. We have systematically explored the structure diversity of metal oxides through atomic-scale solution-chemistries. Several phases of metal oxides have been obtained, such as Fe³⁺ doped CeO₂, TiO₂ (rutile, anatase, brookite), BiPO₄ (high-temperature monoclinic, low-temperature monoclinic, tetragonal). With these phases syntheses, we are able to get insight into the nanoscale chemistry (like the surface hydration) for novel properties which include the advanced catalytic activity.
