Metal Phosphonate Chemistry

Layered compounds are a kind of functional materials with wide applications in the areas such as optics, electrics, magnetism, catalysis, ion exchange and transportation and sensors. The isolation of graphene from graphite has led to an incredible revival of the traditional layered compounds, and the related research has been extended to the other layered inorganic materials. The inorganic-organic hybrid materials composed of metal ions and organic ligands bear advantages of being structurally designable and functionally tunable. The exploration of hybrid materials with low dimensionality and interesting properties remain to be a main current challenge in this field.

As an important class of inorganic-organic hybrid materials, metal phosphonates have received increasing attentions in the past two decades owing to their potential applications in ion-exchange and absorption, catalysis, and materials science. Most of the known metal phosphonates show layered or pillared layered structures in which the inorganic layers are separated by the organic groups. They exhibit high thermal and water stabilities, structural diversity and tunable functions. Our research work focuses on the assembly of new crystalline metal phosphonate materials with novel architectures and interesting physical and chemical properties, developing low-dimensional materials based on metal phosphonates, and studying their optical, magnetic, proton conductive and elctrocatalytic properties.

Research interests: (1) Assembly of crystalline and low-dimensional materials based on metal phosphonates; (2) Magneto-optical metal phosphonates; (3) Proton conductive metal phosphonates for clean-energy applications; (4) Chiral metal phosphonates at molecular and macroscopic levels; (5) Electrocatalysts based on metal phosphonates
