Abstract

A series of Cu catalysts supported on SiO₂, Al₂O₃-SiO₂, TiO₂ rutile, and Cu/TiO₂ anatase metal oxides has been studied for methanol reforming in the vapor phase. The highest activity was obtained on Cu/SiO₂ catalysts (5493 μmol H₂ min^-1·g_cat ^-1) followed by Cu/TiO₂ rutile, Cu/Al₂O₃-SiO₂, and anatase. XRD and HRTEM characterization after reaction revealed that on Cu/SiO₂ significant sintering occurred during reaction. In contrast, the particle size growth on Cu/TiO₂ rutile and anatase was less pronounced, which could be associated with the interaction between Cu clusters and TiO₂. Characterization by TGA showed that on Cu/Al₂O₃-SiO₂ the main cause of deactivation was coke deposition.
