Abstract: This study focuses on the development of novel photo-catalytic materials and their application in the degradation of methylene blue dye in textile wastewater. The research investigates Pr 6 O 11 / Nd 2 O 3 /GO, Pr 6 O 11 / Nd 2 O 3 , Pr 6 O 11 /GO and Nd 2 O 3 /GO composites. The composite materials photo-catalytic activity is evaluated for different light exposure durations. The results demonstrate that the generated composite materials exhibited greater photo-catalytic efficiency than individual catalysts. Moreover, the Pr 6 O 11 , Nd 2 O 3 and GO based composites shows acceptable thermal stability up to 700 °C. Photoluminescence (PL) detects emission electronic transition was ⁓2.64 eV. The indirect optical gap of Pr 6 O 11 /Nd 2 O 3 /GO composite hits 5.6 eV. Moreover, the ternary compositions had the best dye removal performance, reaching a maximum removal efficacy of 92.3% after 150 min. The potential of these composite materials to remove methylene blue dye and its use in eco-friendly water treatment techniques are highlighted in the study.
