The invention discloses a
nitrogen-doped porous
graphite-like carbon
nanosheet as well as preparation and electrocatalytic application thereof. The carbon
nanosheet has a flaky morphology, and is richin
nitrogen doping amount, large in pore volume, high in mesoporous ratio, and highly graphitized as a whole. According to the preparation of the carbon
nanosheet, a
metal oxide nanosheet of
manganese is taken as a template, a
metal organic framework material is taken as a
carbon source, a sandwich-type sandwich
composite structure precursor material is formed by the template and the
carbon source, the precursor material is pyrolyzed in an
atmosphere without water or
oxygen, the template is removed through
acid treatment, the obtained product after the removal of the template is mixed with anitrogen source, and annealing is performed again to prepare the carbon nanosheet. A preparation method has the advantages that the raw materials are easy to obtain, the preparation is simple, the production cost is low, the
macro preparation is easy to implement and the like, and provides a universal synthetic
route for preparing a two-dimensional doped
porous carbon material with high degree ofgraphitization from the
metal organic framework material. At the same time, the invention also discloses the application of the
nitrogen-doped porous
graphite-like carbon nanosheet with a high specific surface and a rich mesoporous structure and as a metal-free catalyst to high-efficiency electrocatalytic
oxygen reduction reactions.
