Cu-Mn-O catalysts were prepared by co-precipitation and hydrothermal method at the different calcination temperature. These catalysts were characterized by BET, XRD, SEM and the catalytic activity for the reduction of NO by propane was evaluated. XRD results showed that Cu1.5Mn1.5O4 was the main phase in all these samples. The NO conversion over the catalysts prepared by hydrothermal method was markedly...
Solid alkali catalyst was prepared with CH3COONa immobilized on alumina by impregnation method. Represented with SEM, IR and BET techniques, the catalysts indicated relatively uniform particle size distribution with perfect particle surface area, pore volume and pore size. Soybean oil was catalyzed to investigate the catalysis characteristics. The results showed that the maximum conversion rate of...
In this abstract, a significantly efficient modification method for Sm2Ti2S2O5 was introduced by employing both reduction and oxidation cocatalysts to improve the H2 activity from water. The modified photocatalyst Sm2Ti2S2O5 is loaded with Ag2S and Rh.The preparation of Ag2S/Sm2Ti2S2O5 involves a one-pot synthesis of by sulfurizing a mixed oxide consisting of Ag, Sm, and Ti, followed by deposition...
Catalytic ozonation of p-chlorobenzoic acid (p-CBA) in aqueous solution has been carried out where transitional metal (Ni, Cu, Mn, Co, Fe) supported activated carbon was used as catalysts. Ni supported activated carbon ( Ni/AC) catalyst, which is prepared by the dipping method with an aqueous solution of Ni(NO3)2, shows higher catalytic activity. Activated carbon and Ni/AC catalyst were characterized...
Activated carbon (AC) supported titanium dioxide (TiO2 ) photocatalyst (TiO2/AC) was prepared by two-step sol-gel process. Crystal structure, and surface morphology of TiO2/AC were characterized by X-ray diffraction (XRD), N2 adsorption-desorption isotherm measurements (BET) and scanning electron microscopy (SEM), respectively. The results show that average crystal size of TiO2 in 11% TiO2/AC catalyst...
Degussa P25 TiO2 loaded on activated carbon fibers (TiCVACFs) was prepared by using the sodium carboxymethyl cellulose (CMC) as the adhesive. The surface morphology and microstructure of TiCVACFs photocatalyst were characterized by SEM, EDS, BET and XRD. The photocatalytic activities of TiCVACFs to flowing low concentration gaseous toluene (1-3 mg/m3) were investigated. It was observed that TiO2 loaded...
