The present study outlines the synthesis of cadmium sulfide-metal–organic framework (CdS-MOF) MIL-101 (Fe) heterojunctions achieved via fast microwave-assisted reactions. Thus, different CdS-MOF ratios were prepared to their effectiveness as photocatalysts. These compounds employed in photocatalytic degradation methylene blue (MB) under UV and visible irradiation. Structural, morphological, textural, compositional, optical properties synthesized determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), UV–vis spectroscopy, Raman Fourier transform infrared (FTIR) utilized characterize structural, properties. Electrochemical impedance (EIS) was also determine photovoltage photocurrent densities. resulting valence band offset (Vfb) gap energy values construct an scheme. Our research revealed that heterojunction enhances efficiency electron–hole pair separation, thereby mitigating charge carrier recombination effects. Moreover, type I electronic structure established efficient reaction mechanism, effectively suppressing photogenerated pairs. system demonstrated exceptional behavior, achieving complete MB removal within 30 min time exhibiting outstanding stability reusability after four cycles. findings highlight potential field wastewater treatment for organic pollutants, offering a promising alternative current environmental issues.
