Water contamination by organic dyes has become a reason for severe environmental pollution and has been threatening the aquatic ecosystem. In this present report two distinct types of copper aluminosilicate (CAS) composites to be utilized as a decreased trigger have been created by incorporating copper nanoparticles through a mesoporous aluminosilicate structure generated through a co-precipitation strategy, accompanied by calcinations at a range of conditions lacking the use of patterns. the thermal inquires, Fourier transform infrared (FT-IR) spectroscopy, XRD (X-ray diffraction) of powder estimation, microscopy using scanning electron microscopy (SEM), and the analysis of energy dispersive X-rays (EDAX) were carried out to analyze the nanocomposites that have been described earlier. The catalytic reduction tests confirmed the importance of Aluminosilicate and the high catalytic activities of the synthesized Cu/Aluminosilicate composite toward nitrophenol reduction.The kinetic analysis of the nitrophenol reduction of the catalyst has fitted the pseudo-first-order kinetic model. More than 99% removal efficiency was still present, demonstrating exceptional stability of the composite. In conclusion, the Cu/Aluminosilicate NPs composite was found to be a promising catalyst for the excellent catalytic activity to reduce a model pollutant nitrophenol from the aqueous solution in the presence of NaBH4 with catalytic efficiency higher than 99% and a reduction rate constant, kred, higher than 0.86 min–1 respectively.
