Biomolecule-assisted solvothermal synthesis of 3D hierarchical Cu2FeSnS4 microspheres with enhanced photocatalytic activity

3D hierarchical Cu2FeSnS4 microspheres were successful synthesized by a novel environment-friendly solvothermal approach with the utilization of l-cystine, an amino acid, as a coordination agent and sulfur donor. The 3D hierarchical Cu2FeSnS4 exhibits high efficiency in the photodegradation of RhB under visible light illumination.
