Highly efficient oxidation of 2,2′-hydrazobis-isobutyronitrile to 2,2′-azobis-isobutyronitrile over a CrOx/TiO2 catalyst with hydrogen peroxide

A green and recyclable heterogeneous CrO_x/TiO₂ catalyst was developed for highly efficient oxidation of 2,2′-hydrazobis-isobutyronitrile to 2,2′-azobis-isobutyronitrile with hydrogen peroxide under mild conditions.
