1. A process for preparing a solid ozone storage material comprising contacting cyclodextrins and/or cyclodextrin derivatives in solid form with a gas comprising ozone, whereby a solid ozone storage material is obtained,
wherein said cyclodextrin derivative is a chemically modified, cross-linked, immobilized cyclodextrin and/or organized in a molecular superstructure,
wherein a chemically modified cyclodextrin is a cyclodextrin of which at least one hydrogen atom and/or at least one hydroxyl radical is substituted with an atom or chemical group selected from a halogen atom, an alkyl group, a hydroxyalkyl group, a thioalkyl group, a sulfhydryl group, an acetyl group, a silyl group, an acyl group, a sulphonyl group, an amine group, a sulphoalkylether group, a sulphate group, a phosphate group, a carboxyl group, a carboxylester group, a quaternary ammonium group, a glucosyl group, a maltosyl group or a chlorotriazinyl group, and
wherein, when contacted with the gas comprising ozone, the cyclodextrins and/or cyclodextrin derivatives are free of any molecule different from a water molecule and capable of reacting with ozone.
