METHOD OF PRODUCING CORE-SHELL CATALYST PARTICLE AND CORE-SHELL CATALYST PARTICLE PRODUCED BY THIS PRODUCTION METHOD |
摘要 |
A method of producing a core-shell catalyst particle, the method including: preparing a core particle that contains an alloy including a first core metal having a standard electrode potential of at least 0.6 V and a second core metal having a standard electrode potential lower than that of the first core metal; eluting the second core metal at least at a surface of the core particle, the elution being carried out under conditions at which an equilibrium is maintained for the first core metal between a metal state and a hydroxide and at which an equilibrium is maintained for the second core metal between a metal state and a metal ion; and, with the core particle being designed as a core portion, coating this core portion with a shell portion after the elution of the second core metal.
