CATALYST ADSORPTION METHOD AND ADSORPTION DEVICE

摘要

A catalyst adsorption method can sufficiently adsorb a catalyst to a lower portion of a recess formed in a substrate. A substrate 20 in which a recess 22 is formed is prepared. Then, a catalyst 23 formed of nanoparticles coated with a dispersant is adsorbed to a surface of the substrate 20 by bringing the substrate 20 into contact with a catalyst solution 12 containing the catalyst by a catalyst adsorption device 10. At that time, a high frequency vibration is applied to the catalyst solution 12.
