Abstract

Dysprosium chromite (DyCrO3) nanoparticles and dysprosium chromite-reduced graphene oxide (DyCrO3-rGO) nanocomposite were synthesized by using a hydrothermal technique. The rGO incorporated DyCrO3-rGO photocatalyst demonstrated up to 87% efficiency to degrade rhodamine B dye which is higher than those of DyCrO3 and commercial Degussa P25 titania nanoparticles. DyCrO3-rGO also generated approximately 3 times greater amounts of hydrogen via water splitting compared to that produced by the P25 titania nanoparticles. The outcome of this investigation might be helpful for synthesizing rGO-based nanocomposite heterostructures for superior solar energy-driven applications.
