Recently, considerable attention has been paid to develop novel Fenton-like oxidation systems for environmental remediation. The activation of periodate (NaIO4) is a desirable oxidation process that drive redox reactions to produce abundant reactive oxygen species (ROS) by a suitable activator. This study reports a simple hydrothermal-calcination route for forming novel tree-branch-like copper-manganese oxides (CuMnOx@MnOx, CMM) nanoarrays, and the production of radical species from NaIO4 induced by CMM for the removal of rhodamine B and 4-chlorophenol from wastewater. The synergistic effects of Cu oxides and Mn oxides composite significantly elevated the activation of periodate, exhibited excellent degradation performance in the CMM/NaIO4. Furthermore, reduced copper species and mixed-valence manganese species play a major role in reaction via XPS anal. Addnl., the underlying degradation mechanism of this work was systematically researched by radical quenching tests and EPR anal. Superoxide anion radical (·O–2) was the major free radicals in this system, simultaneously the production of non-radical singlet oxygen (1O2) via the electron transfer, which are contributed to remove organic pollutants. This work provides a facile way for fabricating monolithic multi-component metal oxides, and new insights into understand activation mechanism of manganese-based periodate activator.
