一般描述

硅胶是硅胶的刚性三维网络。它专门用作齐格勒-纳塔催化剂中活性钛（III）中心的载体材料。硅胶可以经受控制破碎，并形成具有窄粒度分布和高堆积密度的均匀聚合物颗粒。硅胶分类如下：
a.水凝胶 - 孔内充满了水
b.干凝胶 - 通过蒸发过程，气孔中的水相被去除
c.气凝胶 - 通过超临界萃取除去溶剂。

应用

Chromatographic Separation: Silica gel is widely used as a stationary phase in chromatography for the separation of various chemical compounds. Innovations in silica gel modification, such as pentabromobenzyl group-modified silica gel, have enhanced the separation efficiency for metabolites like nicotinamide. This application is critical for pharmaceutical analysis and metabolomics studies, providing high precision and accuracy in the quantification of biologically relevant molecules (Ozaki et al., Analytical Biochemistry, 2022).

Environmental Pollutant Detection: Silica gel is used to create molecularly imprinted polymers (MIPs) that selectively recognize and bind environmental pollutants. A notable application involves the embedding of quantum dots in molecularly imprinted silica gel to detect aminoimidazo-azaarenes (AIAs) in food samples. This method offers high selectivity and sensitivity, making it a powerful tool for food safety and environmental monitoring (Qiao et al., Current Analytical Chemistry, 2021).
