Supported amines are considered as adsorbents to replace aqueous amines for carbon capture and for CO2 capture/conversion into chemicals. Here, amines are grafted to SiO2 or TiSiO2 by using aminopropyl triethoxysilane (APTES) or (3‐triethoxysilylpropyl)‐tert‐butylcarbamate (TESPtBC) and then removi...
