触媒の分析方法
Document Type and Number:
Japanese Patent JP6695776
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a catalyst analyzing method that permits accurate analysis of element distribution in catalysts.SOLUTION: A catalyst 2a analyzing method comprises a step of covering the surface of the catalyst 2a containing a porous carrier with a resin film 4, a step of embedding a catalyst 2b covered with the resin film 4 in thermosetting resin to prepare a specimen 8, a step of exposing a cross section 2c of the catalyst 2b by treating the specimen 8 by at least either cutting or grinding, and a step of irradiating the cross section 2c with at least one of electron beams and X rays thereby to detect at least one of the electron beams or the X rays derived from the cross section 2c. The resin film 4 contains at least one of cyanoacrylate or polycyanoacrylate. Alternatively, the resin film 4 may be formed of topcoat agent.SELECTED DRAWING: Figure 2
