Simultaneous photocatalytic degradation of methylene blue and methyl orange using a green synthesized Zn_0.98Mn_0.02O/BiOCl nanocomposite

Abstract

The Zn0.98Mn0.02O/BiOCl nanocomposite shows potential activity for the photocatalytic degradation of methylene blue and methyl orange. The primary role of superoxide and hydroxyl radicals is confirmed by radical scavenger studies.

“…The photocatalytic process generally takes place at catalytic surfaces or within a few monolayers around them where the produced free radicals (generally ˙OH and O 2 ˙) initiate the corresponding redox reaction, thereby gradually converting organic pigments into non-hazardous byproducts such as CO 2 and H 2 O. 14–17 With the coupling of adsorption and photocatalysis, a synergistic effect occurs, improving the overall catalytic degradation performance. Research in the field of photocatalytic degradation is currently at the forefront of addressing environmental challenges, 18,19 particularly in tackling water pollution caused by different organic dyes.…”
