In this study, the Solid-State Dispersion (SSD) method was utilized to prepare composite photocatalysts of eggshells (ES)/TiO₂ in various ratios. TiO₂ and eggshell photocatalysts were also employed as control samples. The samples were characterized using X-ray Diffraction (XRD) to analyze the crystalline structure and phases, along with High-Resolution Transmission Electron Microscopy (HRTEM) to examine the morphology and surface structure at the microscopic level. These characterizations support the data analysis, offering insight into the relationship between structural and morphological properties and the photocatalytic performance of the composites. The photocatalytic efficiency of the composite was assessed in a suspension system using methylene blue (MB) solution as the target pollutant. Among the three different ratios, the ES/TiO2 (9:1) composite achieved the highest adsorption and 95.63 % photocatalytic degradation of MB. This indicates that the adsorptive capacity of eggshells is very high, even though it primarily serves as a support for TiO₂ in the ES/TiO₂ composite photocatalyst. The increased surface area of the TiO₂/eggshell composite photocatalyst enhanced MB solution adsorption and photocatalytic degradation, thereby improving its effectiveness.
