Evaluation of APTES-Functionalized Zinc Oxide Nanoparticles for Adsorption of CH and CO.

ZnO nanoparticles functionalized with APTES were obtained to evaluate their CH and CO adsorption at 298 K in a range between 0 and 10 bar. First, ZnO nanoparticles were obtained by a precipitation method and subsequently coated with (3-aminopropyl)triethoxysilane (APTES). As a preliminary study, the results were compared with previously reported naked nanoparticles in order to evaluate the influence of APTES coating on CO selectivity.
