Title:
燃料電池酸素極のための多層触媒
Document Type and Number:
Japanese Patent JP5197590
Kind Code:
B2
Abstract:
A supported catalytic material including multiple mixed-valence nanoclustered metal or metal oxide catalytic layers or regions and/or multiple organometallic catalytic layers. The supported catalytic material may include two or more compositionally-distinct mixed-valence nanoclustered metal or metal oxide layers or regions arranged as layers or discrete regions. The mixed-valence regions or layers may include two or more metals in two or more oxidation states. The supported catalytic material may also include two or more compositionally- distinct organometallic regions or layers, where the layers or regions differ with respect to the chemical identity of the metal and/or ligands to which the metal is coordinated.
