Abstract:
Studying surface of catalyst nanoparticles in a flowing liquid is important for understanding the underlying mechanism of a reaction performed in liquid. We report the design of a reaction cell system of Si3N4 window covering the flowing liquid with an electron-transmissible membrane. By using metal nanoparticles as a catalyst dispersed in a solvent, examination of the surface of catalyst nanoparticles in a flowing liquid was demonstrated by observation of Ag 3d photoemission feature when a liquid containing Ag nanoparticles was flowing through this system.
