Anwendung

The unique physical properties such as high surface area and ordered pore structure of mesoporous silica combined with the selectivity of amine and thiol functional groups make them useful for diverse applications. For example amine and thiol modified mesoporous silica finds applications in CO2 sequestration, heavy metal (such as Pb, Fe, Au etc.) removal from waste water or industrial waste streams. Also, the ability of the amine and thiol modified mesoporous silica to bind the metallic nanoparticles such as Pt or Pd render them useful as novel catalytic support. The functionalization of mesoporous silica with amine and thiol also makes them useful for entrapping biological entities and for investigations involving the study of the effect of quantum confinements of molecules/solvent within the ordered mesopores.

The enzyme organophosphorus hydrolase (OPH) was spontaneously entrapped in carboxylethyl- or aminopropyl-functionalized mesoporous silica with rigid, uniform open-pore geometry (30 nm). This approach yielded larger amounts of protein loading and much higher specific activity of the enzyme when compared to

Sequestration of CO2, either from gas mixtures or directly from air (direct air capture, DAC), could mitigate carbon emissions. Here five materials are investigated for their ability to adsorb CO2 directly from air and other gas mixtures. The sorbents studied
