Abstract
Background
CO2 capture in air is an important issue nowadays. Cerium oxide has been reported to be a good adsorbent for CO2. However, its adsorption capacity and adsorption strength are not high enough. La-modified CeO2 was used in this study.
Methods
In this study, a new adsorbent of La-modified CeO2 solid solution were prepared from aqueous solution of cerium and lanthanum hydroxides by microwave method with radiation power 539 W and frequency 2.45 Hz. These hydroxides were prepared by precipitation of Ce(NO3)3 and La(NO3)3 solution, The materials were characterized by powder X-ray diffraction, energy dispersive X-ray spectroscopic, scanning electron microscopy, infrared spectroscopy, and nitrogen sorption.
