(57) Abstract:
(EN): A manganese oxide material and a method for preparing same, relating to the technical field of catalytic materials and environmental protection. The manganese oxide material comprises manganese dioxide, wherein the valence form of the manganese element comprises divalent manganese and tetravalent manganese, and the ratio of the divalent manganese to the tetravalent manganese is 0<Y(Mn2+)/Y(Mn4+)<1. The manganese oxide material has a spherical structure consisting of nanorods and a favorable pore passage. The manganese oxide material has good thermal stability, large specific surface area, and strong adsorption and ion exchange capabilities during use, features high catalytic activity and long service life under a high humidity condition, and can efficiently remove hazardous materials such as CO, VOCs, and O3 (ozone) and kill staphylococcus, etc. either alone or simultaneously. The method for preparing a manganese oxide material is environment-friendly, simple, practicable, extensively available, low in cost, and easy to implement industrialization.
(FR): L'invention porte sur un matériau à base d'oxyde de manganèse et sur un procédé pour la préparation de celui-ci, en ce qui concerne le domaine technique des matériaux catalytiques et de la protection de l'environnement. Le matériau à base d'oxyde de manganèse comprend du dioxyde de manganèse, la valence de l'élément manganèse comprenant du manganèse divalent et du manganèse tétravalent et le rapport du manganèse divalent au manganèse tétravalent étant de 0<Y(Mn2+)/Y(Mn4+)<1. Le matériau à base d'oxyde de manganèse a une structure sphérique constituée de nanobâtonnets et d'un passage poreux favorable. Le matériau à base d'oxyde de manganèse a une bonne stabilité thermique, une grande surface spécifique et de fortes capacités d'adsorption et d'échange d'ions pendant l'utilisation, il présente une activité catalytique élevée et une longue durée de vie dans des conditions d'humidité élevée et il permet d'éliminer efficacement des matières dangereuses telles que le CO, les COV et l'O3 (l'ozone) et de tuer les staphylocoques, etc. soit individuellement, soit simultanément. Le procédé pour la préparation du matériau à base d'oxyde de manganèse est respectueux de l'environnement, simple, pratique, largement disponible, à faible coût et facile à mettre en œuvre à une échelle industrielle.
