TiO(2)@PEI-Grafted-MWCNTs Hybrids Nanocomposites Catalysts for CO(2) Photoreduction

Anatase (TiO(2)) and multiwalled carbon nanotubes bearing polyethylenimine (PEI) anchored on their surface were hybridized in different proportions according to a sol-gel method. The resulting nanocomposites (TiO(2)@PEI-MWCNTs), characterized by BET, XRD, XPS, SEM, and UV techniques, were found effi...

description Anatase (TiO(2)) and multiwalled carbon nanotubes bearing polyethylenimine (PEI) anchored on their surface were hybridized in different proportions according to a sol-gel method. The resulting nanocomposites (TiO(2)@PEI-MWCNTs), characterized by BET, XRD, XPS, SEM, and UV techniques, were found efficient catalysts for CO(2) photoreduction into formic and acetic acids in water suspension and under visible light irradiation. PEI-grafted nanotubes co-catalysts are believed to act as CO(2) activators by forming a carbamate intermediate allowing to accomplish the first example in the literature of polyamines/nanotubes/TiO(2) mediated CO(2) photoreduction to carboxylic acids.
