Research Overview
Research Overview
Our core research area is the development of carbon capture, utilization, and storage (CCUS*) technologies based on advanced materials. We are currently pursuing two major research directions: 1. CO₂ Capture, and 2. CO₂ Utilization. Looking ahead, we aim to 3. broaden the application of our materials to a wide range of chemical, environmental, and energy-related fields.*CCUS (Carbon Capture, Utilization, and Storage): A key technology for carbon neutrality that captures CO₂ from emission sources and enables either long-term storage or value-added conversion for utilization.
1. CO₂ Capture and Direct Air Capture (DAC)
1. CO₂ Capture and Direct Air Capture (DAC)
Development of advanced liquid, solid, and composite/hybrid sorbent materials capable of selectively and efficiently capturing CO₂ across a wide concentration range—from industrial point sources (3–55%) such as power plants, steel mills, cement kilns, and biogas facilities, to atmospheric CO₂ (~400 ppm).
A) Liquid Absorption Materials
Design, synthesis, and application of hydrogen-bond-based Deep Eutectic Solvents (DES) for high-performance CO₂ absorption.
B) Solid Adsorption and Membrane Materials
Development of adsorption and membrane systems based on Metal–Organic Frameworks (MOFs), Covalent Organic Frameworks (COFs), and Hydrogen-Bonded Organic Frameworks (HOFs).
C) Composite/Hybrid Materials for CO₂ Capture
Porous Liquids (PL): Fluid materials possessing permanent nanopores that enable gas uptake while retaining liquid-like flow.
DES@Porous Materials (Liquid-in-Solid Strategy): Composite materials synthesized by impregnating or encapsulating functional DES into porous solids for enhanced CO₂ capture performance.
2. CO₂ Conversion and Utilization
2. CO₂ Conversion and Utilization
Research on reaction-control technologies and functional materials that convert captured CO₂ into valuable chemicals.
A) Reactive Capture and Conversion (RCC)
Simultaneous CO₂ capture and catalytic conversion enabled by functional materials.
B) Mineral Carbonation for Advanced Material Synthesis
Control of crystallization mechanisms through tailored microreaction environments to synthesize innovative metal carbonates—such as CaCO₃, MgCO₃, and NaHCO₃—with tunable properties (nanoparticle size, morphology, polymorph, etc.).
3. Future Research Interests
3. Future Research Interests
Expansion of material applications across environmental, separation, and energy-related fields, with a focus on next-generation solutions for global sustainability challenges.
Electrochemical CO₂ Capture
Energy-efficient CO₂ capture achieved through electrochemical control of selective adsorption and desorption, enabling non-thermal regeneration and the design of electroactive capture materials.
Sustainable Separation Technologies
Application of functional materials for acid gas removal (SOₓ, NOₓ), wastewater treatment, and other environmentally critical separation processes.
