(EN) The present invention provides for an ice-nucleating particle for cloud seeding and other applications, which can initiate ice nucleation at a temperature of -8 degC. Further, the ice nucleation particle number increased continuously and rapidly with the reducing of temperature. The ice nucleating particle in the present invention is a nanostructured porous composite of 3-dimensional reduced graphene oxide and silica dioxide nanoparticles (PrGO-SN). The present invention also provides for a process for synthesizing the PrGO-SN.
(ZH) 本发明提供了用于播云和其他应用的冰成核颗粒,其可以在‑8℃的温度下引发冰成核。进一步地,随着温度降低,冰成核颗粒数目连续且快速增加。本发明中的冰成核颗粒是3维还原氧化石墨烯和二氧化硅纳米颗粒的纳米结构多孔复合物(PrGO‑SN)。本发明还提供了用于合成PrGO‑SN的方法。
