Tuning the gold nanoparticle catalyzed carbon monoxide PROX reaction to purify hydrogen gas

(Phys.org)—A group of researchers from Trinity University in San Antonio and The Pennsylvania State University have developed a catalytic system using supported gold nanoparticles that surpasses industry standards by controlling space velocity of feed water, the monolayer coverage of water on the nanoparticle surface, and reaction temperature. Their work appears in Nature Chemistry.
