57 Zusammenfassung AB [EN] Composites comprising an exfoliated graphite support material having a degree of graphitization g in an range of 50 to 93 %, obtained by XRD Rietveld analysis, which is coated with ZnO nanoparticles. These composites are produced by three different methods: A) (syn) the method comprises the following consecutive steps: i) a Zn(II)salt is dissolved in a solvent ii) graphite and a base are added simultaneously iii) the mixture is stirred under impact of ultrasound iv) the solvent is removed from the suspension or B) (pre) the method comprises the following consecutive steps: i) graphite is suspended in a solvent and exfoliated via impact of ultrasound ii) a Zn(II)salt and a base are added simultaneously forming nano-ZnO particles iii) the mixture is stirred iv) the solvent is removed from the suspension or C) (post) the method comprises the following steps: i) a Zn(II)salt and a base are mixed in a solvent in a first reactor forming nano-ZnO particles ii) graphite is exfoliated via impact of ultrasound in a second reactor iii) both suspensions of i) and ii) are mixed together iv) after step iii) the solvent is removed from the suspension. These coated composites may be tempered in a further step and again coated and again tempered.
[FR] L'invention concerne des composites comprenant un matériau support en graphite exfolié présentant un degré de graphitisation g compris dans la plage de 50 à 93 %, obtenu par une analyse de Rietveld XRD, ledit composite étant revêtu de nanoparticules de ZnO. Ces composites sont produits par trois procédés différents : a) (syn) le procédé comprend les étapes consécutives suivantes : i) dissoudre un sel de Zn(II) dans un solvant, ii) ajouter simultanément du graphite et une base, iii) agiter le mélange soumis à un impact d'ultrasons, iv) extraire le solvant de la suspension ; ou B) (pre) le procédé comprend les étapes consécutives suivantes : i) mettre en suspension le graphite dans un solvant et l'exfolier par l'impact d'ultrasons, ii) ajouter simultanément un sel de Zn(II) et une base pour former des particules de nano-ZnO, iii) agiter le mélange, iv) extraire le solvant de la suspension ; ou C) (post) le procédé comprend les étapes suivantes : i) mélanger un sel de Zn(II) et une base dans un solvant dans un premier réacteur pour former des particules de nano-ZnO, ii) exfolier le graphite par l'impact d'ultrasons dans un second réacteur, iii) mélanger les deux suspensions de i) et ii) ; iv) après l'étape iii), extraire le solvant de la suspension. Ces composites revêtus peuvent être recuits dans une autre étape, puis revêtus à nouveau et recuits à nouveau.
