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

Abstract

Mehdi, et al.. Degradation of methylene blue using synthesized nanostructured CuO with high specific surface area through catalytic oxidation. ABSTRACT Nanostructured CuO (CuO Nst) with specific surface area of 144.473 m 2 /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 Original Research Article EI Farrouji et al.; IRJPAC, 8(4): 190-197, 2015; Article no.IRJPAC.2015.084 191 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.
