The invention belongs to the technical field of materials, and discloses a
noble metal@hollow ordered
mesoporous carbon nanospheres as well as a preparation method and application thereof. According to the preparation method, through ''reactive interface assisted
self assembly'', the reactive hollow cavity template agent, namely,
noble metal@SiO2 core-shell nanospheres containing
aldehyde group chemical functional groups on the surfaces are designed and synthesized,
aldehyde groups on the surface of the
noble metal@SiO2 nanospheres react with phenolic groups of resol in situ in the self-
assembly process to form covalent bonds, so that the interaction force between a shell layer source and the hollow cavity template agent is greatly enhanced, and the surfaces of the noble
metal@SiO2 nanospheres can be uniformly coated with a
polymer coating; after a
carbonization reaction is performed and the SiO2 template is removed, the noble
metal@hollow ordered
mesoporous carbon nanospheres are obtained; and the shell layer has the advantages of regular and ordered pore arrangement, a
large pore size, narrow pore size distribution and the like, and the nanospheres can be used in the fields of chemical
catalysis,
antibiosis, electrocatalysis and the like.
