Description
Summary:[Display omitted] •It is optimized a method for the preparation of mixed oxide/ZrO2 sumicron diameter fibers materials.•The formulation of catalysts is optimized in order to enhance the catalytic properties of materials.•The role of dopants and synthesis parameters on the chemical structure and catalytic activity for propane ODH is discussed. The first part of present paper described the synthesis procedure for the preparation of VOx/ZrO2 catalysts with fibrous morphology. In the present contribution, the same procedure is applied for the preparation of multimetallic catalysts, such as V-Mo-O/ZrO2 and V-Nb-O/ZrO2. In all the cases, and in only one step, the multimetallic porous fibers were obtained. The characterization data has shown that the segregation of metal atoms is adequate, avoiding the formation of oxides such as V2O5, Nb2O5 and/or Mo2O3, and the activity under the propane ODH reaction of VOx based catalysts is improved by the addition of Mo.
