The nanoreactors were fabricated by reacting amphiphilic quaternary ammoniums and polyoxoperoxometalates K_n[PW_12-xTi_x-O_40-x(0₂)_x] (x=1, 2 and 3; n = 5, 7 and 9) (K₅[PW₁₁TiO₃₉(O₂)], K₇[PW₁₀Ti₂O₃₈(O₂)2] and K₉[PW₉Ti₃O₃₇(O₂)3]). Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) were used to characterize the resulting samples. This kind of nanocatalysts could promote NH₄SCN' degradation into simple inorganic compounds such as SO₄^2-, HCO₃^- and NO₃^- only using oxygen as an oxidant under room conditions.
