title: Oxidation of SCN- with air and micellar polyoxoperoxometalates.
abstract: The nanocatalysts were fabricated by reacting amphiphilic quaternary ammoniums with polyoxoperoxometalates (POPMs) K(n)[PW(12-)(x)Ti(x)O(40-)(x)(O(2))(x)](x=1, 2 and 3; n=5, 7 and 9). Fourier transform infrared spectroscopy (IR), transmission electron microscopy (TEM), and UV-vis-NIR spectrophotometer were used to characterize the resulting samples. This kind of nanocatalysts could provide a kind of nanoreactors to promote the degradation of NH(4)SCN into simple inorganic compounds such as SO(4)(2-), HCO(3)(-) and NO(3)(-) using oxygen as an oxidant under room conditions. The leaching test showed that the POPMs micellar catalyst had excellent stability and could be used as a heterogeneous one at least five times.
