Light-weight mesoporous composite aerogel material and preparation method thereof

The invention provides a light-weight mesoporous composite aerogel material and a preparation method thereof. The light-weight mesoporous composite aerogel material comprises a MxWOyFz/SiO2 composite aerogel material, wherein MxWOyFz is a nanoparticle with visible light penetration and near-infrared light (lambda is more than or equal to 780nm) shielding functions, M is Li, Na, K, Rb or Cs, x is more than or equal to 0 and less than or equal to 0.5, y is more than 2 and less than (3+x)/2, and z is more than or equal to 0. The light-weight mesoporous composite aerogel material is scientific and reasonable in formula and overcomes multiple problems in the prior art; the material has excellent heat insulation and medicine load and controlled release properties besides the near-infrared absorption/heat absorption and near-infrared shielding functions. The invention further discloses a preparation method of the light-weight mesoporous composite aerogel material. The preparation method is simple and feasible, and c
