Synthesis and Photocathodic Protection Properties of MO/SnO₂ Core-Hell Nanocomposites

Abstract:

A series of MO/ SnO₂ (MO=MnO₂, and CoO) core-hell nanocomposites were synthesized by a combined layer-by-layer technique and hydrothermal method. The results showed that SnO₂ or CoO loading enhanced the electron storage ability. When loading 3.0 wt% MnO₂ and 5.0 wt% CoO on SnO₂ nanotubes, after TiO₂ coating electrode was irradiated under UV irradiation for 1 h, the self-discharging time of the MnO₂/SnO₂and MnO₂/SnO₂ core-hell nanocomposites electrodes was more than 7.5 h and 7.7 h, respectively. In addition, the as-synthesized MO/ SnO₂ core-hell nanocomposites coatings exhibited good photocathodic protection property for metals.
