Title:
COMPOSITE BODY, CATALYTIC INK, AND METHOD FOR MANUFACTURING COMPOSITE BODY
Document Type and Number:
WIPO Patent Application WO/2024/029558
Kind Code:
A1
Abstract:
This composite body includes molybdenum disulfide particles and palladium particles. The molybdenum disulfide contained in the molybdenum disulfide particles has an average crystallite size of 150 nm or less as determined from the peak at 2θ = 14.4°±0.5° obtained by an X-ray diffraction measurement. This catalytic ink includes the composite body and a dispersion medium. This method for manufacturing the composite body comprises a step for mixing a palladium solution and molybdenum disulfide particles together. The molybdenum disulfide contained in the molybdenum disulfide particles has an average crystallite size of 150 nm or less as determined from the peak at 2θ = 14.4°±0.5° obtained by an X-ray diffraction measurement.
