Abstract

The $BaCrO_4$ nanoparticles were synthesized from a 0.1 M $K_2CrO_4$ and 0.1 M $BaCO_3$ solution with stirring for 10 h. The product was washed several times with acetone and heated to $700^{\circ}C$ for 6 h. At that time, the color of mixture was a greenish yellow. The graphene/$BaCrO_4$ nanocomposites were prepared with graphene and $BaCrO_4$ nanoparticles by stirring in tetrahydrofuran and heated in an electric furnace at $700^{\circ}C$ for 2 h. The $BaCrO_4$ nanoparticles, graphene/$BaCrO_4$ and heated graphene/$BaCrO_4$ nanocomposites were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The graphene/$BaCrO_4$ nanocomposites and heated graphene/$BaCrO_4$ nanocomposites were evaluated as a photocatalyst and discussed about kinetics study for the degradation of organic dyes, such as methylene blue and rhodamine B under ultraviolet light irradiation at 254 nm.
