Photostimulation response type material as well as preparation method and application thereof

The invention discloses a photostimulation response type material as well as a preparation method and application thereof. The photostimulation response type material takes silicon dioxide nanospheres as a carrier, Ag particles are doped on the carrier, and the surface of the Ag-doped carrier is modified by an amine compound. The preparation method comprises the following steps of: mixing silicon dioxide nanospheres doped with a morphology template agent, a silane coupling agent, silver nitrate and a reducing agent for reaction, and then removing the morphology template agent to obtain Ag-doped silicon dioxide nanospheres; and mixing the Ag-doped silicon dioxide nanospheres with an impregnant and an amine compound for reaction to obtain the photostimulation response type material. The material can realize the performance of adsorbing CO2 in darkness and releasing CO2 under light stimulation at low concentration, normal temperature and normal pressure. When the material is sprayed on plant leaves, a CO2 micro-
