Complete oxidation of benzene on CoCr and CoCr oxide catalysts

Catalytic activity of active carbons impregnated before activation of pinewood sawdust and nutshells to be used on the control of atmospheric emissions

“…Kim investigated the complete oxidation of benzene, toluene, and xylene, using metal catalysts (Cu, Mn, Fe, V, Mo, Co, Ni and Zn) supported on different materials (␥-Al 2 O 3 , TiO 2 and SiO 2 ), concluding that copper supported on ␥-Al 2 O 3 had the best catalytic activity, due to better dispersion of active sites on the support [5]. Vass and Georgescu also studied the complete oxidation of benzene using mixtures of metal oxides (Cu-Cr and Co-Cr) as catalysts, supported on ␥-Al 2 O 3 and on ␥-Al 2 O 3 + SiO 2 , concluding that copper-chromium had higher activity than cobalt-chromium, the catalysts supported on ␥-Al 2 O 3 being more active than the ones supported on ␥-Al 2 O 3 + SiO 2 [11].…”

Evaluating the potential of CNT-supported Co catalyst used for gas pollution removal in the incineration flue gas

“…Many catalysts have been developed for catalytic oxidation, such as Pd, Rh, Pt, Ru, Au, Cu, Co, and Cr, supported on Al 2 O 3 (Kobayashi et al, 2001;Morà n-Pineda et al, 1999;Toebes et al, 2001;Vass and Georgescu, 1996;Wang, 2004). The performance of catalytic oxidation depends not only on the active metal but also on the support; the activity of a catalyst will be enhanced by a support that has superior antacid and antalkali properties, high surface area, and high pore volume and is hydrophobic (Goncalves and Figueiredo, 2004).…”

Spinel-Type Cobalt Chromites as Novel and Highly Ortho-selective Catalysts for Phenol Alkylation

“…Previously, spinel-type cobalt chromites have showed special catalytic performance in various chemical processes, such as water gas shift reaction, combustion catalysis and the total oxidation of halogenated hydrocarbons [14][15][16][17][18]. In this work, we attempt to use the spinel-type cobalt chromites as novel catalysts for the ortho-alkylation of phenol with methanol.…”
