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。硅胶允许可控破碎，导致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 - 气孔充满了水
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的溶剂

应用

硅胶用于比较 MCM-41 型中孔吸附剂。

Catalyst Architecture for Stable Single Atom Dispersion Enables Site-Specific Spectroscopic and Reactivity Measurements of CO Adsorbed to Pt Atoms, Oxidized Pt Clusters, and Metallic Pt Clusters on TiO

Leo DeRita et al.

Journal of the American Chemical Society, 139(40), 14150-14165 (2017-09-14)

Oxide-supported precious metal nanoparticles are widely used industrial catalysts. Due to expense and rarity, developing synthetic protocols that reduce precious metal nanoparticle size and stabilize dispersed species is essential. Supported atomically dispersed, single precious metal atoms represent the most efficient

Dissipative water intrusion in hydrophobic MCM-41 type materials.

T Martin et al.

Chemical communications (Cambridge, England), (1)(1), 24-25 (2002-07-18)

Texture-related features of water intrusion in hydrophobised MCM-41 silicas render these materials especially suitable for energy dissipation in mechanical dampers.
