Abstract: [Solution] The present invention relates to a method for partially oxidizing an alkane, including contacting an alkane with a supported catalyst in a presence of an oxidizer to convert the alkane into an aldehyde, wherein the supported catalyst is composed of a bimetallic oxide and a support carrying the bimetallic oxide, and the bimetallic oxide is represented by the following formula and includes oxygen and two metals selected from metals of groups 8 to 10 of the periodic table: AmBnOx wherein the bimetallic oxide and support are each a metal selected from metallic elements of groups 8 to 10 of the periodic table; the bimetallic oxide and support are not the same metallic element; m, n, and x mean amounts ((mmol)) of the bimetallic oxide, the support, and oxygen, respectively, per 1 g of the supported catalyst; m is more than 0 [mmol/g-cat] and less than 1 [mmol/g-cat]; n is more than 0 [mmol/g-cat] and less than 1 [mmol/g-cat]; and x is a value [mmol/g-cat] satisfying oxidation states of the bimetall

Abstract: The present invention relates to nickel-cobalt-manganese-based compound particles which have a volume-based average secondary particle diameter (D50) of 3.0 to 25.0 ?m, wherein the volume-based average secondary particle diameter (D50) and a half value width (W) of the peak in volume-based particle size distribution of secondary particles thereof satisfy the relational formula: W?0.4×D50, and can be produced by dropping a metal salt-containing solution and an alkali solution to an alkali solution at the same time, followed by subjecting the obtained reaction solution to neutralization and precipitation reaction. The nickel-cobalt-manganese-based compound particles according to the present invention have a uniform particle size, a less content of very fine particles, a high crystallinity and a large primary particle diameter, and therefore are useful as a precursor of a positive electrode active substance used in a non-aqueous electrolyte secondary battery.
