Title: Method for measuring dispersibility of noble metal and dispersibility measuring instrument
Inventor: NAGAI YASUTAKA
IPC: G01N31/10
Filed: 2003-05-13
Abstract: <P>PROBLEM TO BE SOLVED: To measure a dispersibility with a high precision even in a catalyst using an oxide having an oxygen absorbing/discharging capacity.  <P>SOLUTION: In such a state that the catalyst is cooled to a sufficiently low temperature capable of suppressing the formation of a carbonate seed, CO is adsorbed by the catalyst and the adsorption amount of CO is measured while the amount of an active noble metal being the amount of the noble metal having adsorbed CO is calculated from the adsorption amount of CO and the dispersibility of the noble metal is calculated from the ratio of the amount of the active noble metal to the total amount of the noble metal supported on the catalyst. The formation of the carbonate seed can be suppressed by adsorbing CO at a sufficiently low temperature and the lowering of measuring precision caused by the increase in the apparent adsorption amount of CO by the formation of the carbonate seed can be prevented.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
