One route identified for green hydrogen production in recent years has been the reforming of oxygenated hydrocarbons derived from biomass to hydrogen. The research of Dumesic and coworkers showed that the reforming of oxygenated hydrocarbons over supported platinum catalysts can offer several advantages [1]. These include the possibility of using nonvolatile feed streams such as sugars, as well as additional hydrogen and minimal CO production resulting from driving the water-gas shift reaction with high water partial pressures. Recent research has centered on bimetallic alloys, which have promoted rates over monometallic platinum [2]. In this work the activity, selectivity, and stability of platinum-cobalt on carbon nanotubes support is investigated in light of its structure as evaluated by operando x-ray absorption spectroscopy (XAS) and transmission electron microscopy (TEM).
