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 gro...

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 mainta...

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 r...

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 ...
