Co

Cobalt oxide/hematite (Co3O4/α-Fe2O3) composites were synthesized by using goethite as precursor via co-precipitation calcination method and employed in the catalytic degradation of benzene. The catalysts properties of the Co3O4/α-Fe2O3 composites were investigated by means of X-ray diffraction (XRD...

520			\|a Cobalt oxide/hematite (Co3O4/α-Fe2O3) composites were synthesized by using goethite as precursor via co-precipitation calcination method and employed in the catalytic degradation of benzene. The catalysts properties of the Co3O4/α-Fe2O3 composites were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 adsorption measurement (BET), X-ray photoelectron spectroscopy (XPS) and H2 temperature programmed reduction (H2-TPR) techniques, respectively. The results showed that the Co3O4/α-Fe2O3 composite had excellent catalytic oxidative performance on catalytic degradation of gaseous benzene, and its catalytic activity were influenced markedly by the ratio of Co3O4 and the calcination temperature. When the composite catalyst with the Co/Fe molar ratio of 0.6, calcined temperature at 500 °C and benzene initial concentration was 1000 mg/m3, the catalyzed oxidative temperature which benzene completely conversion and 91.7% CO2 selectivity was 400 °C. Large specific surface area, abundant surface oxygen species and strong redox properties which were ascribed to the interaction between Fe2O3 and Co3O4 play an important role in the catalyzed oxidative degradation of benzene.

Large specific surface area, abundant surface oxygen species and strong redox properties which were ascribed to the interaction between Fe2O3 and Co3O4 play an important role in the catalyzed oxidative degradation of benzene. α-FeOOH α-Fe Co Benzene Catalytic oxidation degradation Zhu, Yi verfasserin aut Lu, Jun verfasserin aut Zhu, Chengzhu verfasserin aut Zhu, Mengyu verfasserin aut Xie, Qiaoqin verfasserin aut Chen, Tianhu verfasserin aut Enthalten in Solid state sciences Amsterdam [u.a.] : Elsevier, 1999 93, Seite 79-86 Online-Ressource (DE-627)325294852 (DE-600)2035101-X (DE-576)094081069 1293-2558 nnns volume:93 pages:79-86 GBV_USEFLAG_U SYSFLAG_U GBV_ELV GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_90 GBV_ILN_95 GBV_ILN_100 GBV_ILN_105 GBV_ILN_110 GBV_ILN_150 GBV_ILN_151 GBV_ILN_224 GBV_ILN_370 GBV_ILN_602 GBV_ILN_702 GBV_ILN_2003 GBV_ILN_2004 GBV_ILN_2005 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2027 GBV_ILN_2034 GBV_ILN_2038 GBV_ILN_2044 GBV_ILN_2048 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2056 GBV_ILN_2059 GBV_ILN_2061 GBV_ILN_2064 GBV_ILN_2065 GBV_ILN_2068 GBV_ILN_2111 GBV_ILN_2112 GBV_ILN_2113 GBV_ILN_2118 GBV_ILN_2122 GBV_ILN_2129 GBV_ILN_2143 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2152 GBV_ILN_2153 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2507 GBV_ILN_2522 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4251 GBV_ILN_4305 GBV_ILN_4313 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4326 GBV_ILN_4333 GBV_ILN_4334 GBV_ILN_4335 GBV_ILN_4338 GBV_ILN_4393 35.90 Festkörperchemie 33.61 Festkörperphysik AR 93 79-86

abstract	Cobalt oxide/hematite (Co3O4/α-Fe2O3) composites were synthesized by using goethite as precursor via co-precipitation calcination method and employed in the catalytic degradation of benzene. The catalysts properties of the Co3O4/α-Fe2O3 composites were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 adsorption measurement (BET), X-ray photoelectron spectroscopy (XPS) and H2 temperature programmed reduction (H2-TPR) techniques, respectively. The results showed that the Co3O4/α-Fe2O3 composite had excellent catalytic oxidative performance on catalytic degradation of gaseous benzene, and its catalytic activity were influenced markedly by the ratio of Co3O4 and the calcination temperature. When the composite catalyst with the Co/Fe molar ratio of 0.6, calcined temperature at 500 °C and benzene initial concentration was 1000 mg/m3, the catalyzed oxidative temperature which benzene completely conversion and 91.7% CO2 selectivity was 400 °C. Large specific surface area, abundant surface oxygen species and strong redox properties which were ascribed to the interaction between Fe2O3 and Co3O4 play an important role in the catalyzed oxidative degradation of benzene.
