Abstract
The invention relates to a catalyst that comprises a mesoporous oxide matrix, with said matrix comprising at least one oxide of an element X that is selected from among silicon and titanium, taken by itself or in a mixture, with said catalyst comprising at least the tantalum element and the niobium element, with the tantalum mass representing between 0.1 to 30% by weight of the mass of the mesoporous oxide matrix, the niobium mass representing between 0.02 to 6% by weight of the mass of the mesoporous oxide matrix, the content by mass of the tantalum element being greater than or equal to the content by mass of the niobium element. The invention also relates to the use of this catalyst in a method for the production of 1,3-butadiene from a feedstock that comprises at least ethanol.
