Nickel oxide (NiO) and praseodymium oxide mixed nickel oxide (Pr 2 O 3 -NiO) catalysts was synthesized using modified sol-gel method for CO 2 adsorption. The synthesized catalysts was characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive of x-ray (EDX) and N 2 gas adsorption-desorption to study their physical and chemical properties. The capability of catalyst to adsorb CO 2 was tested using temperature programmed desorption of CO 2 (TPD-CO 2 ) and their interaction was also studied. It was found that, Pr 2 O 3 -NiO catalyst have a remarkable CO 2 uptake capacity (331.40 µmol/g) as compared to NiO (32.53 µmol/g). This is governed by the presence of cubic Pr 2 O 3 and less crystalline sample. Moreover smaller particle size and larger BET surface area of Pr 2 O 3 -NiO catalyst provided good chemical interactions between Pr 2 O 3 -NiO and CO 2 molecules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
