Overview of inorganic research area

Synthesis and development of inorganic materials and metal complexes for application of magnetism, catalysis and energy

Tunghai inorganic research interests cover the material, coordination, supramolecular, organometallic and bioinorganic chemistry. We focus on solid-state materials synthesis, magnetic molecules, microporous metal-organic frameworks (MOFs), energy storage and conversion, photo/electrochemical homogeneous and heterogeneous catalysis for water splitting, organometallic chemistry and bioinspired coordination complexes.

 

Advanced composite materials for energy storage and conversion

Our research aims to explore the advanced materials for energy conversion and storage. We are particularly interested in graphene-based composites and 2D transition metal dichalcogenides. We have used the above-mentioned nanomaterials as the electrode materials for supercapacitors and lithium ion batteries. In the aspect of energy conversion, we focus on the development of bifunctional electrocatalysts for overall water splitting. To understand the reactions and mechanisms in the electrode/electrolyte interfaces, we are developing a series of in-situ analytical techniques for the above studies.

 

Coordination polymers and supramolecular materials

We are concerned in the research of inorganic coordination polymers and supramolecular materials using self-assembly synthesis strategy. Using the designed organic ligands to coordinate with different metal centers, we have successful design and synthesize several microporous metal-organic frameworks (MOFs) with diverse structures, and high-spin multinuclear metal clusters. We also in-depth explore the chemical regulation mechanism in supramolecular self-assembly from simple systems to complex systems, as well as the relationship between the structure of the material itself and its magnetic, optical, and electrical properties. The pore sizes and magnetic properties of the frameworks can be turned by changing the different metal centers and organic ligands, and it is further applied in the detection and decomposition of pollutants in wastewater and the chemical catalysis.

 

Development of molecular and solid-state catalysts

Our goal is to create the molecular and solid-state catalysts for water splitting producing hydrogen and carbon dioxide reduction reaction. We synthesize the low-valence and low-coordination molecular metal complexes to screen for the activations of water, carbon dioxide and other important small molecules (CO, O2, CH4 and N2O) and design the novel catalytic reactions with organic substrates to generate fine chemicals. In addition, we also develop the combination of metallic particles with their metal fluorides/oxides to perform the significant catalytic efficiency for the heterogeneous electrocatalytic water-reduction reaction.
