Polyethylenimine-functionalized SBA-15 mesoporous silica for CO2 direct air capture and conversion to methane in a coupled catalytic reactor

Polyethylenimine-functionalized SBA-15 mesoporous silica for CO2 direct air capture and conversion to methane in a coupled catalytic reactor

Technologies that capture and store or utilize CO2 have the potential to reduce the concentration of this gas in the atmosphere or provide carbon-neutral energy vectors. In this work, materials based on mesoporous silica SBA-15 functionalized with different polyethylenimine (PEI) loadings, i.e. 30,...
