Electrocatalyst for preparation of chlorine by electrolysis of chlorine ion containing electrolytes comprising at least one precious metal oxide and/or noble metal of subgroup VIIIa of the periodic table of the elements (in particular selected from the group of Ru, Rh, Pd, Os, Ir, Pt ), finely…
Disclosed are ruthenium nanoparticles having an essentially face-centered cubic structure. Disclosed is a method for producing ruthenium nanoparticles having an essentially face-centered cubic structure. This production method includes a step (i) of maintaining a solution containing ruthenium (III)…
The present invention is a catalyst for use in a fuel electrode of a polymer solid electrotype fuel cell which is formed by making a carbon powder support platinum and ruthenium thereon, and is characterized in that the loading ratio between platinum and ruthenium is from 1:2.5 to 1:4 (in molar…
Provided is a catalyst for selective oxidation of CO gas in a gas of essentially hydrogen, and a method for producing the catalyst. The catalyst is highly active in a relatively high temperature range. The catalyst is for selectively oxidizing CO gas with hydrogen, and this carries ruthenium held…
