Abstract
The dispersion state of Pt nano-particles supported on Al2O3 was investigated by gas chemisorption. The amount of H2 chemisorption was larger than that of CO over the entire range of Pt dispersion. Pt dispersion beyond 100 % was estimated for Pt/Al2O3 with nano-sized Pt particles by H2 chemisorption. FT-IR measurements of hydrogen species adsorbed on Pt/Al2O3 with different Pt dispersions revealed that hydrogen species dissociatively adsorbed on Pt nano-particles and spilled over onto Al2O3. Hydrogen species dissociatively adsorbed on Pt nano-particles were highly reactive with NO at room temperature, leading to the formation of N2. In contrast, hydrogen species spilled over onto the fringes of Pt particles reacted with NO to form N2O.
