Abstract
Zinc-doped copper sulfide (Zn-doped CuS) particles were synthesized by a hydrothermal method in EG (EG) solutions of different concentrations. The results showed that the concentration of EG could regulate the structural morphology of Zn-doped CuS, and the Zn-doped CuS formed in pure EG had a porous nanotubular structure, and its photocatalytic degradation efficiency of methylene blue was as high as 96 % under visible light with good stability. SEM and TEM imaging confirmed that the diameter of the Zn-doped CuS with porous nanotubular structure was 100 nm, and the wall thickness was 30 nm. This study presents a strategy to enhance the photocatalytic activity and performance of CuS for environmental applications through EG concentration and zinc doping.
期刊介绍:
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
