Solid-state Materials

Our group applies the principles of synthetic molecular chemistry to the development of solid-state hybrid semiconducting materials. We focus on the design and synthesis of hybrid systems that combine the tunable functionalities of molecules with the robustness and extended structure of solids.  

Colloidal Nanocrystals

We extend our molecular design strategy to the synthesis of luminescent nanocrystals, focusing on ligand and crystal engineering to enhance electronic and optical performance. By precisely tuning surface ligands, crystal structure, and defect passivation, we improve charge transport and boost light-harvesting and emission efficiencies.

Displays (Emerging-LEDs, OLEDs)

For applications in displays and solid-state lighting, we fabricate efficient light-emitting diodes based on organics (OLEDs) and emerging nano-materials. Additionally, we are interested in circularly polarized light (CPL) emitting devices. 

Furthermore, to bring the metaverse to life, we focus on modulating the light path emitted from OLEDs to achieve high-resolution near-eye displays.

CO2 reduction

With industrialization accelerating worldwide, the large amount of greenhouse gases generated by the indiscriminate use of fossil fuels is becoming the main cause of global warming. Therefore, it is of prime importance to reduce the large amounts of carbon dioxide (CO2). In this context, we are focusing on converting CO2 into CO, CH4, and C2+ products using photocatalysts (PCs) and electrocatalysts (ECs). For this purpose, we will synthesize novel catalytic materials and perform the electrochemical reaction in various cells. 

Water splitting

Hydrogen stands out among sustainable fuels as a leading contender for achieving a carbon-neutral society, thanks to its high energy density (~120 kJ/g), exceptional energy conversion efficiency, and sustainability. However, the predominant methods for hydrogen production today—natural gas reforming, coal gasification, biomass gasification, and the reforming of renewable liquid fuels—result in significant CO2 emissions. In light of this, water electrolysis (WE) emerges as a promising alternative, offering a method to produce 'green hydrogen' without the associated CO2 emissions. To enhance WE reactions, we aim to synthesize new spin-catalysts that can facilitate the oxygen/hydrogen evolution reaction and increase the efficiency of anion-exchange membrane water electrolysis (AEMWE) and anion-exchange membrane fuel cell (AEMFC).
