Photochemical synthesis and characterization of novel samarium oxide nanoparticles: toward a heterogeneous Bronsted acid catalyst

Samarium oxide nanoparticles (Sm2O3NP) were prepared photochemically for the first time. Characterization shows spherical, polydisperse Sm2O3NP stabilized by 4-HEBA, a substituted benzoic acid. The Sm2O3NP also possess Bronsted acidity. This new material may prove to be a potent heterogeneous acid catalyst.
