In this study, visible-light copper bismuth oxide (CuBi2O4) photocatalyst were synthesized via co-precipitation (CuBi2O4-C) and microwave-assisted methods (CuBi2O4-M). The X-ray powder diffraction (XRD) analysis reveals the presence of pure tetragonal, along with band gaps of 2.9 eV in both samples. The microwave-assisted method produced flower-like CuBi2O4 microspheres, which had a larger BET surface area and demonstrated the highest photocatalytic performance, approximately 83.4 % in the decolorization of malachite green (MG) dye under visible light. Therefore, the research suggested a facile strategy for the fast synthesis of CuBi2O4 microspheres under mild reaction conditions. The use of microwave heat treatment is a faster and more efficient way to photocatalyst materials, while also being cost-effective and energy-saving.
HIGHLIGHTS
- The flower-like CuBi2O4 microspheres synthesized via the microwave-assisted method offer a promising approach for efficient and cost-effective photocatalysis, particularly in the degradation of malachite green dye under visible light. This study highlights the potential of microwave synthesis in enhancing the photocatalytic performance of CuBi2O4 materials
