Degradation of Methylene Blue Using Synthesized Nanostructured CuO with High Specific Surface Area through Catalytic Oxidation

Nanostructured CuO (CuO Nst) with specific surface area of 144.473 m2/g has been successfully synthesized via a facile solution-phase method at room temperature. As prepared CuO was characterized using x-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) and transmission electron microscopy (TEM). The synthesized CuO was demonstrated as efficient and re-used catalyst in degradation of methylene blue in the presence of sodium hypochlorite through catalytic oxidation. More than 95% of the methylene blue was degraded after 30 min. After 5 successive catalytic cycles, the as-prepared CuO still remained its original catalytic activity, exhibiting good reusability and durability.
