Abstract: This study successfully leveraged chicken eggshells to fabricate sulfur-doped calcium carbonate(S/CaCO₃) nanocomposite semiconductor materials. The synthesis process employed the sol-gel method through two eco-friendly steps. The first stage is the synthesis of calcium oxide nanoparticle precursors (CaO Nps) from chicken egg shell powder waste. Subsequently, the CaO Nps were dispersed in a methanol-glycerol mixture, and thiourea was added as the sulfur source. Characterization techniques, including Thermogravimetric-Differential Thermal Analysis (TG-DTA), Fourier Transform Infrared spectroscopy (FTIR), X-Ray Diffraction (XRD), and Ultraviolet-Visible Diffuse Reflectance Spectroscopy (DRS-UV-Vis), were employed to analyze the synthesized material. The results showed that a semiconductor S/CaCO₃ nanocomposite with a size of 22.72 nm, and the bandgap energy decreases from the CaO Nps precursor by 5.67 eV to 1.82 eV for the S/CaCO₃ nanocomposite. The formation of the S/CaCO₃ nanocomposite was confirmed by the overlapping crystal phases at 2 θ between CaCO₃ (vaterite), and sulfur, as well as the FTIR analysis revealing a characteristic S=O stretching at 1148 Cm^-1. The obtained percentage of the S/CaCO₃ nanocomposite was 57.09%, indicating that further optimization is possible to achieve a higher product yield.
