“…Commercial catalytic wet oxidation processes rely on both, homogeneous such as Fe 2þ or Cu 2þ and heterogeneous catalysts such as noble metals: iridium (Ir) gold (Au), platinum (Pt), palladium (Pd), rhodium (Rh) and rhenium (Re), and ruthenium (Ru); metal oxides: FeO(OH), CuO-ZnO; and mixed metallic catalysts Fe-Cu-Mn, Cu-Zn, CoAlPO 4 -5 and CeO 2 , Fe-CeO 2 , perovskite-type oxide LaFeO 3 , and heteropolyacids (HPAs) or the supported precious metal and/ or base metal oxide catalysts Mikulova et al, 2007;Yang et al, 2007;Carrier et al, 2009;Li et al, 2009b;Zhang et al, 2009b). The support materials that can be employed to enhance the CWAO are CeO 2 , TiO 2 -CeO 2 , TiO 2 , ZrO 2 and graphite, activated carbon, Al 2 O 3 , and carbon nanofibres (Oliviero et al, 2000;Chang et al, 2003;Milone et al, 2006;Quintanilla et al, 2007;Rodriguez et al, 2008).…”

“…Keggintype polyoxotunstates (H 4 SiW 12 O 40 and Na 2 HPW 12 O 40 ) decreased significantly the activation energy for the CWAO of Acid Orange 7 and shifted the oxidation mechanism from a free radical chain reaction to an electron transfer [124]. Zhang et al [125] reported the excellent catalytic activity of polyoxomolybdate (Zn 1.5 PMo 12 O 40 ) with nanotube structure for the CWAO of Safranin-T, in which a 98% of color and a 95% of COD were removed within 40 min under room temperature and atmospheric pressure. Safranin-T was totally mineralized to simple inorganic species such as HCO 3 − , Cl − , and NO 3 − .…”

“…In previous reports by the current authors [7,8], oxidation catalysts such as polyoxometalates Zn1.5PW12O40 and Zn1.5PMo12O40 were used for the removal of organic dyes under room temperature and atmospheric pressure using air as an oxidant. However, the separation of catalysts after use is another key issue that needs to be solved in terms for practical applications.…”

One-dimensional MoO 3 nanofibers doped with Ce (MoO 3 : CeO 2 ) are synthesized by a method combining a sol-gel process and an electrospinning technique. The resulting MoO 3 : CeO 2 is characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR) spectroscopy, and scanning electron microscopy (SEM). The catalytic degradation of rhodamine B and safranin-T with MoO 3 : CeO 2 nanofiber catalyst is investigated in a continuous flowing mode using air (O 2 ) as an oxidant. The results show that rhodamine B and safranin-T are degraded effectively and the removal efficiencies are 98.3%, and 98.5%, respectively. In addition, the organic dyes are totally mineralized to simple inorganic species such as CO 3 -, Cl -and NO 3 -.
