文摘

Aqueous polyoxometalate (H₃PMo₁₂O₄₀) solution reduced by CO with liquid water using gold nanoparticle catalysts at room temperature, which contains protons in liquid water and electrons associated with the reduced polyoxometalate, can produce gaseous H₂ or can hydrogenate benzene over an electrochemical cell consisting of a simple carbon anode, a proton-exchange membrane, and a Pt- or Rh-based cathode. In the present cell, H₂ can be produced from the reduced H₃PMo₁₂O₄₀ solution at voltages that are lower by about 1.15 V compared to water electrolysis.
