Abstract
A layered ruthenic acid compound is converted to a protonic layered ruthenic acid hydrate, which is then converted to a layered alkylammonium-ruthenic acid intercalation compound to obtain a colloid containing ruthenic acid nanosheets having a thickness of 1 nm or smaller. Thereby, a ruthenic acid nanosheet is obtained.
