RESEARCH AREA


Brief Introduction

Our laboratory that first started in 2005 mainly researches the syntheses of nanoparticles and their applications. We have synthesized gold, heterometallic nanostructures and metal/metal-oxide nanostructures by polyol process and thermolysis in solution phase. On the base of these acheivements, we are researching about surface modification and functionalization as well as sizes and shapes of gold nanoparticles. In addition, we are doing a variety of measurements about localized surface plasmon resonance and surface-enhanced Raman spectroscopy and theoretical calculation of each of the single metal particles for sensing applications. For the catalytic application of these nanoparticles, we have focused on the precise control of particle size, shape, and uniformity. For high catalytic efficiency, it is necessary to reduce metal particle sizes and thereby increase surface areas and active sites such as edges and kinks. The general form of heterogeneous catalysts is tiny metal particles embedded on silica and metal oxide supports, because highly active metal nanoparticles are effectively stabilized by supports having high surface area. The supports prevent the aggregation of the particles and in some cases, they form new active components on the interface with metals.
