Surface scientific approach for developments in fuel cell's catalysts

From catalytic perspective, molecular-level understanding of surface phenomena occurring at nano-sized metal (alloy) particle surfaces is a key for developing highly active and durable catalysts. Our experimental approach for studying catalysis is preparations of well-defined metals or alloy surfaces by using ultra-high vacuum (UHV) and molecular-beam-epitaxy (MBE) techniques. We routinely use UHV-MBE, surface vibrational spectroscopy (IR, Raman), scanning probe microscopy (SPM), electron spectroscopy (XPS), electrochemical (EC) voltammetry, gas-chromatography (GC) etc., and try to clarify the solid surface phenomena on atomic, molecular-levels. We believe our research results directly link to future eco-friendly society.
