Abstract

Active and selective Cu_x(CeZrY)_1-xO_y catalysts (pure and with addition of Al₂O₃ and Cr) for the steam reforming of methanol were synthesized via the urea-nitrate combustion method. Structural, surface and redox characteristics of these catalysts were investigated by XRD, BET, IR spectroscopy, differential dissolution (DD), H₂-TPR and XPS methods. It was shown that addition of alumina and Cr leads to the steep increase in H₂ production due to appearance of highly dispersed copper species and stabilizes their activity. The parallel change of SRM rate constants and maximal rates of reduction with hydrogen characterizing mobility of lattice oxygen at variation of the catalyst composition was revealed that shows the importance of lattice oxygen mobility for steam reforming of methanol.
