Title:
CARBON-SUPPORTED PLATINUM NANOCUBE CATALYST THAT IS SURFACE-PROCESSED WITH RHODIUM ATOMS, PREPARATION METHOD THEREFOR, AND ETHANOL DECOMPOSITION DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/043121
Kind Code:
A1
Abstract:
The present invention provides: a carbon-supported platinum nanocube catalyst that is surface-processed with rhodium atoms, in which the surfaces of platinum nanocubes are decorated with rhodium atoms linked thereto by oxygen, so that ethanol oxidation reaction activity is excellent; a preparation method therefor; and an ethanol decomposition device including same.
