1. Method for the production of a nanocrystalline nickel oxide material comprising the steps of
a) the introduction of a nickel starting compound into a reaction chamber by means of a carrier fluid, wherein the nickel starting compound is an inorganic nickel salt and wherein the nickel starting compound is introduced into the reaction chamber in the form of a solution, slurry, suspension or in solid aggregate state, b) a thermal treatment of the nickel starting compound in a treatment zone by means of a pulsating flow at a temperature of 200 to 550° C., c) the formation of nanocrystalline nickel oxide material, and d) the discharge of the nanocrystalline nickel oxide material obtained in steps b) and c) from the reactor, wherein the inorganic nickel salt is selected from the group consisting of nickel nitrate, nickel hydroxide, and a basic nickel carbonate, and wherein the nickel starting compound has an average particle size of less than 10 μm and is obtained by grinding a suspension of the nickel starting compound.
