Abstract[English]
is Ta, Nb, or a mixture thereof; a is 1.0; b is 0.01 to 0.5; c is 0.005 to 0.2; d is 0.005 to 0.1; and x is the number of oxygen atoms necessary to render the catalyst electrically neutral. The values a, b, c, and d are determined based on the amount of each starting material used to form the catalyst. The catalyst material has a PXRD pattern including peaks at 2θ values of 12.6° ± 0.2°, 18.0° ± 0.2°, 27.9° ± 0.2°, and 29.1° ± 0.2°, wherein the PXRD pattern is obtained using Cu Kα radiation.[French]
est Ta, Nb, ou un mélange de ceux-ci ; a est égal à 1,0 ; b est dans la plage de 0,01 à 0,5 ; c est dans la plage de 0,005 à 0,2 ; d est dans la plage de 0,005 à 0,1 ; et x est le nombre d'atomes d'oxygène nécessaires pour rendre le catalyseur électriquement neutre. Les valeurs a, b, c, et d sont déterminées sur la base de la quantité de chaque matériau de départ utilisé pour former le catalyseur. Le matériau catalyseur présente un motif PXRD comprenant des pics à des valeurs 2θ de 12,6° ± 0,2°, 18,0° ± 0,2°, 27,9° ± 0,2° et 29,1° ± 0,2°, le motif PXRD étant obtenu à l'aide d'un rayonnement Cu Kα.
