The invention discloses a phosphorus-doped double-vacancy heterostructure material, a preparation method and application, and belongs to the technical field of electrocatalysis, polyacid is used as a precursor to prepare P-MoS2 rich in sulfur vacancies on carbon cloth through hydrothermal treatment, then part of MoS2 is converted into MoO2 in situ through heat treatment, and a P-MoS2 / MoO2 heterostructure is constructed. Abundant oxygen vacancies are generated in the thermal conversion process. Rich vacancy defects and heterogeneous interfaces in the constructed catalyst promote electron transfer and adsorption of active substances, charge transfer kinetics is improved, and more reaction active sites are provided for water cracking; the vertically crossed nanosheet network on the carbon cloth is beneficial to charge transport, reactant permeation and gas diffusion. Various components in the catalyst synergistically promote the water electrolysis process, and a novel advanced, economical, efficient and stable electrode material is provided for catalytic application.

The application discloses a fullerene nanomaterial capable of targeting a mannose receptor and a preparation method thereof. The application connects a mannose molecule to a fullerene through an amidation reaction to prepare a fullerene-mannose derivative material with a determined molecular structure. The mannose group targets a mannose receptor overexpressed by a macrophage, so that the fullerene material is efficiently taken by the macrophage, and the superior antioxidant and anti-inflammatory properties of the fullerene are fully exerted in the cell.
