Discovering indium as hydrogen production booster for a Cu/SiO2 catalyst in steam reforming of methanol

Indium is  as an effective H2 production promoter in a Cu/SiO2 catalyst for the steam reformingof methanol. We prepared silica-supported Cu-In catalyst via a urea-assisted co-precipitation method that showed a higher H2 productivity compared to the monometallic catalyst and a H2/CO2 molar ratio of almost 3 at 493 K. By means of XPS, XRPD and HRTEM-EDX along with H2 and CO-TPR, H2O-TPD, and N2O titrations, supported by computational modeling, the superior performances were attributed to an easier H2O activation due to lower oxidation state of the Cu, resulting from the electron density transfer from the InOx phase.
