文摘

The present study has developed a straightforward and efficient route for the synthesis of quite spherical β-AgVO₃/ZnFe₂O₄ nanocomposites under ambient conditions in the absence of any cosurfactants. Field emission scanning electron microscopy, powder X-ray powder diffraction, energy dispersive X-ray spectroscopy, X-ray fluorescence spectromety, Fourier transform infrared spectroscopy, UV diffuse reflectance spectroscopy, photoluminescence, Brunauer, Emmett Teller analysis, and dynamic light scattering techniques have been used for proof of the formation and characterization of the structure, size, surface morphology, and phase composition of the suggested nanocomposites. The prepared nanocomposites have been used as both a catalyst and a photocatalyst. Results of the differential scanning calorimetry and UV–visible spectroscopy analyses show that, due to their synergistic effects, our synthesized nanocomposites can significantly increase the catalytic thermal decomposition of the ammonium perchlorate and photocatalytic degradation of the methylene blue, compared to their constituent nanoparticles (i.e., β-AgVO₃ and ZnFe₂O₄).
