Preparation of nanoporous alumina using aluminum chloride via precipitation templating method for CO adsorbent

Publication date: 25 November 2018Source: Journal of Industrial and Engineering Chemistry, Volume 67Author(s): Changju Yeom, Rengaraj Selvaraj, Younghun KimAbstractA cost-effective preparation method is proposed to prepare nanoporous alumina (NA) using aluminum chloride as a precursor with a lower cost than aluminum butoxide. In addition, the surfactant template was replaced with magnesium stearate, which has a lower unit cost in stearate acid. The adsorption isotherm test for the CO gas was carried out to compare the adsorption performance of the NA adsorbents prepared using post-hydrolysis (NA) and cost-effective precipitation (C-NA). In addition, C-NA exhibited a similar uptake capacity as NA, and the maximum uptake capacity of Pd/C-NA increased 1.3 times via Pd nanodots loading.Graphical abstract
