Regiospecific oxyhalogenation of aromatics over SBA-15-supported nanoparticle group IV-VI metal oxides

Article abstract of DOI:10.1007/s10562-010-0350-z

TiO_x, VO_x, MoO_x and WO_x supported on SBA-15 exhibit efficient catalytic activity for oxyhalogenation of aromatics with the H₂O₂-halide ion system. Unlike the hitherto known solid catalysts, these reusable catalysts yield the para-halogenated product with 100% selectivity at 298 K and moderate acidic pH (3-5). The catalytic activity was enhanced by five orders of magnitude when supported on SBA-15. Springer Science+Business Media, LLC 2010.
