Abstract
The invention discloses a method for preventing oxidative degradation of black phosphorus nanosheets and application thereof, and the method comprises the following steps: carrying out hydrogenation reaction on the black phosphorus nanosheets in a mixed atmosphere of inert gas and hydrogen to obtain hydrogenated black phosphorus nanosheets of which the surfaces are modified with P-H covalent bonds. The surface of the hydrogenated black phosphorus nanosheet is modified with a P-H covalent bond with the molar ratio of 5-10%. In order to improve the stability of the black phosphorus nanosheet, the due catalytic performance is inevitably and greatly reduced by protection or modification measures in the prior art, and particularly, the photocatalytic performance is almost completely lost, however, the black phosphorus nanosheet is subjected to hydrogenation modification, so that the original photocatalytic performance of the black phosphorus nanosheet is basically maintained while the stability of the black phosphorus is improved.
