This study reports on the synthesis, characterization, and application of sodium-lanthanum molybdate [NaLa(MoO4)2] as a photocatalyst in degradation process Coomassie Brilliant Blue G-250 (CBB-250), an environmentally toxic recalcitrant dye derived from triphenylmethane. The highlighted ceramic material was produced by coprecipitation, its properties were studied using range physicochemical techniques including compositional, crystallographic, morphological analyses. Among most relevant information, X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy confirmed formation NaLa (MoO4)2 crystals with tetragonal arrangement. Additionally, scanning electron microscope (SEM) images provide evidence production overlapping plate-like microstructures. nitrogen adsorption isotherms demonstrated that obtained exhibits mesoporous organization, surface area pore diameter equivalent to 45.7 m2 g-1 6.54 nm, respectively. Photocatalytic tests, performed under ultraviolet light irradiation for 120 min, indicated NaLa(MoO4)2 has high oxidative reactivity, achieving >95% CBB-250 present system. reaction velocity constants, estimated accordance Langmuir-Hinshelwood equation, substantiate enhances kinetics (13.7 × 10-3 min-1) throughout photochemical treatment. In growing scientific interest effective strategies removal emerging pollutants contamination matrices, represents promising avenue development innovative technologies this field.
