Abstract
In this scenario, the Pd doped MnO2nanocatalysts were constructed by hydrothermal route. As-synthesized Pd loaded α-MnO2 nanocomposites were systematically characterized by various characterization techniques, respectively. The FESEM and TEM results reveal the surface morphology, the rose flower-like Pd was evenly decorated on the MnO2 surface. The elemental compositions of the presenting elements Pd, Mn and O are confirmed by XPS spectroscopic analysis. The photocatalytic activity of 2% Pd loaded α-MnO2 for crystal violet (CV) degradation was very high compared to immaculate α-MnO2 under visible light embellishment. Moreover, the radical trapping experiment substantiates that O2•− and •OH plays a vital role in CV abatements. This work will provide new in-depth insights into other photocatalytic nanomaterials with potential applications in the field of environmental compensation. Besides, the electron density distributions analysis was carried out for this catalyst to explain the bond length value between the atoms.
