Abstract

The catalytic mechanism of titanium dioxide loading with a chromium oxide (CrO_x/TiO₂) catalyst for the oxidation of 2,2′-hydrazobis-isobutyronitrile to 2,2′-azobis-isobutyronitrile was investigated, which revealed that the surface hydroxyl groups of TiO₂ could promote the formation of the real active center (Cr–O–Ti) for an efficient catalytic oxidation process.
