Abstract

Lanthanum orthoferrite (LaFeO3) photocatalysts were synthesized by a facile and cost-effective coprecipitation method via the hydrolysis of La (III) and Fe (III). The characteristics of LaFeO3 were investigated through thermogravimetric analysis (TGA), X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (DRS), vibrating sample magnetometry (VSM), and transmission electron microscopy (TEM). During the investigation of the applicability of LaFeO3 as a photocatalyst for the atom transfer radical polymerization (ATRP) of methyl methacrylate monomer under UV irradiation, the obtained poly(methyl methacrylate) exhibited a high molecular weight and narrow polydispersity index. In addition, the LaFeO3 can be recovered via application of a magnetic field and reused for the atom transfer radical polymerization process.
