Preparation and catalytic activity of nickel–manganese oxide catalysts with an ilmenite-type structure in the reactions of complete oxidation of hydrocarbons

Destruction of naphthalene via ozone-catalytic oxidation process over Pt/Al2O3 catalyst

“…Comparing with our previous work of which the E and A are 149.97 kJ mol −1 and 3.26 × 10 17 s −1 for the catalytic oxidation of Nap over Pt/Al 2 O 3 in air (without ozone) [12] indicates a reduction of E of 2.2 folds for the case with ozone. Similar findings of the reduction of E in the oxidation of benzene over NiMnO 3 -ilmenite catalyst have been reported by Mehandjiev et al [17,43]. Thus, the present results show that the use of ozone in conjunction with Pt/Al 2 O 3 can greatly reduce the E and facilitate the rate of oxidation of Nap.…”

Manganese-promoted nickel/alumina catalysts for hydrogen production via auto-thermal reforming of ethanol

“…For comparison, AM15, which was prepared by impregnation of manganese on Al 2 O 3 , shows typical peaks of Mn 2 O 3 . Over the NAM10 with both Ni and Mn, besides the spinel peaks of Al 2 O 3 and NiAl 2 O 4 , the peaks of ilmenite-type NiMnO 3 [10], instead of Mn 2 O 3 in AM15, were emerged at 36.6 , 33.7 and 24.6 . To confirm the formation of NiMnO 3 and find the reducibility of catalysts, TPR was conducted over these catalysts.…”

Preparation and catalytic activity of nickel–manganese oxide catalysts in the reaction of partial oxidation of methane

“…Nickelemanganese mixed oxides were prepared from carbonate precursors [13]. The mixed appropriate amounts of manganese and nickel nitrate solutions with Ni/Mn ¼ 1/2 were added into a well-stirred container containing sodium bicarbonate solution at room temperature.…”
