Copper-Molybdenum bimetallic nanoparticles embedded within mesoporous silica nanoparticles supported aluminum (CuMo-MCM-41-Al) was synthesized via a using a one-pot hydrothermal method strategy. The catalyst was characterized by energy dispersive X-ray analysis, scanning electron microscopy, elemental mapping, Brunauer-Emmett-Teller (BET) analysis. Synthesized catalyst was then employed as a heterogeneous Fenton catalyst to degrade artificial methyl orange (MO) dye wastewater and tetracycline antibiotic (TC). A systematic examination was conducted to evaluate the optimum bimetallic mole ratio, the effects of initial H2O2 concentration, pH, and catalyst dosage, on the degradation efficiency of MO and TC. The use of CuMo-MCM-41 based Al catalyst demonstrated highly efficient degradation and removal of MO and TC contaminant, surpassing the performance of both monometallic MCM-41-Al catalysts under the same reaction conditions. The exceptional catalytic activity of CuMo-MCM-41 can be attributed to the high dispersion of metals within the catalyst and the synergistic effects arising from the metals redox cycles. Moreover the presented catalyst shows the remarkable adsorption capacity for Methyl Orange (MO) and Tetracycline (TC) which can be attributed to its high BET surface area and well-defined mesostructure. The Cu3Mo7-MCM-41-Al catalyst exhibits a methyl orange degradation efficiency of 92.53% at a pH of 5.6, catalyst loading of 1.5 g/L, and 0.98 mM H2O2. Additionally, 95% of tetracycline has been degraded under the conditions of pH 5.8, catalyst loading of 0.67 g/L, and 0.73 mM H2O2
