Let's sing a "Song" for Nanocatalysts!
Why are nanocatalysts important in green energy processes?
Why are nanocatalysts important in green energy processes?
We are thoroughly investigating chemistry on well-defined nanostructures and surfaces. We have generated numerous nanostructures with uniform morphologies and studied various catalytic functions stimulated by renewable energy sources. We now focus on nano-assemblies for multi-dimensional functions and small molecule activation by photo- and electrochemical processes using designed nanoparticles.
Starting from the model catalysts, we explore fundamental principles of nanocatalyst design exhibiting high conversion efficiency and selectivity of energy conversion reactions, such as hydrogen generation and carbon dioxide reduction, and pursue to establish green chemical processes beneficial for human life on Earth.

A research team led by Professor Hyunjoon Song from the Department of Chemistry has developed a novel electrode structure utilizing silver nanowire networks—ultrafine silver wires arranged like a spiderweb—to significantly enhance the efficiency of electrochemical CO₂ conversion to useful chemical products.
The research team designed a three-layer electrode architecture that simultaneously repels water and enables efficient charge transport. The structure consists of a hydrophobic substrate, a catalyst layer, and an overlaid silver nanowire (Ag NW) network, which acts as an efficient current collector while preventing electrolyte flooding.
