Abstract

Abstract: Hydrogen production by oxidative steam reforming of methanol (OSRM) or autothermal steam reforming of methanol (ASRM) was investigated over Cu-loaded mesoporous CeO2 and Cu-loaded mesoporous CeO2 –ZrO2 catalysts, synthesized via a nanocasting process using MCM-48 as a hard template, followed by a deposition–precipitation technique. Various Cu contents were loaded on the mesoporous CeO2 and CeO2 –ZrO2 supports. The fresh and spent catalysts were characterized by N2 adsorption–desorption, X-ray diffraction, temperature-programmed oxidation, and X-ray photoelectron spectroscopy. The ASRM results showed that 9 wt% Cu loading onto mesoporous CeO2 and CeO2 –ZrO2 provided the best catalytic performance with 100% methanol conversion and 60% H2 yield at 350° and 300 °C, respectively. Furthermore, the time-on-stream stability testing of the 9 wt% Cu loading catalyst was at 168 h, and the CO selectivity of these two catalysts indicated that the addition of ZrO2 into the catalyst reduced the CO selectivity during the ASRM process. Graphical abstract: Highlights: Cu-loaded mesoporous CeO2 and Cu-loaded mesoporous CeO2 –ZrO2 catalysts are successfully synthesized. The synthesized catalysts containing various Cu contents present high Cu dispersion with high specific surface area. 9 wt% Cu loading catalysts provided the best catalytic performance with 100% methanol conversion. The time-on-stream stability testing of the 9 wt% Cu loading catalyst was at 168 h.
