چکیده
Photocatalytic degradation is becoming an increasingly attractive method for addressing environmental remediation challenges. In this work, pure ZnS, CdS, and ZnS/CdS heterostructure nanocomposites with premier photocatalyst efficiency were synthesized via a simple co-precipitation method followed by a solvothermal procedure. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), and ultraviolet-visible (UV-Vis) absorbance measurement techniques were employed to characterize the structural, morphological, and optical properties. According to the XRD results, ZnS/CdS nanocomposites with an average crystallite size in the range of ۱۵-۲۰ nm were formed. The optical band gap ranging from ۴.۴ eV to ۵.۳ eV was obtained by the UV-Vis measurement. The photocatalytic performance of the ZnS/CdS heterostructure nanocomposites in the degradation of the methylene blue (MB) dyes under UVA light was evaluated. The synthesized ZnS/CdS nanocomposite showed a high decolorization efficiency in a short time (۹۹%) in just ۵ min, under UVA irradiation. This simple approach can be upscaled for industrial use.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
