T. Yamato et al., Highly efficient Nafion-Ce(IV) or Nafion-Cr(III)-catalysed oxidation of polycondensed aromatic hydrocarbons with co-oxidant, J CHEM R-S, (11), 2000, pp. 522-523
A Ce(IV) or Cr(III) impregnated Nafion-K catalyst was found to be effective
in promoting the dehydrogenative oxidation of polycondensed aromatic hydro
carbon with NaBrO3 as a co-oxidant.
