Abstract

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.

摘要

在室温下，使用金纳米颗粒催化剂，通过一氧化碳和液态水对多金属氧酸盐（H3PMo12O40）水溶液进行还原，该溶液含有液态水中的质子以及与还原后的多金属氧酸盐相关的电子，在由简单碳阳极、质子交换膜和铂基或铑基阴极组成的电化学电池上可产生气态氢气或使苯氢化。在当前电池中，与水电解相比，在电压降低约1.15 V的情况下，可从还原后的H3PMo12O40溶液中产生氢气。
