Carbon Shell-Encapsulated Metal Alloy Catalysts with Pt-Rich Surfaces for Selective Hydrogen Oxidation Reaction

Invited for this issue's Front Cover are the groups of Kwang Bok Yi and Namgee Jung from Chungnam National University (South Korea). The Front Cover shows the catalyst structure that blocks O-2 gas (red circles) penetration and selectively permeates H-2 gas (blue circles) via the molecular sieve effect by the carbon shell coated on the metal surface to suppress reverse current flow under shut-down/start-up conditions during fuel cell operation.
