“…The catalyst systems used in reforming reactions are closely related to those that have been applied for the synthesis of methanol [3,4]. They are mostly based on copper dispersed in a matrix formed by pure or mixed oxides like ZnO [5,6], Al 2 O 3 [7], ZnO/A 2 O 3 [8], Cr 2 O 3 /Al 2 O 3 [9,10], and ZrO 2 /Al 2 O 3 [9].…”

The aim of the work was to investigate how the size of Ni and Cu-supported nanoparticles influence their activity in an oxidative steam reforming of methanol. The size of metal particles was controlled by the initial introduction or elimination of oxygen-containing groups on the surface of carbon nanotubes. The results of the activity tests showed that catalysts with the smallest metal nanoparticles were the least active since they easily underwent oxidation during the process.
