Localized surface plasmon resonance effect driven fabrication of core/shell Au NRs@MnO2 nanosheets

This work proposes a controllable, green and facile strategy for preparing Au NRs@MnO 2 core/shell nanosheets by photodeposition using the localized surface plasmon resonance (LSPR) effect of gold nanorods (Au NRs). MnO 2 is produced by the reduction of KMnO 4 with the LSPR effect induced photoelectrons. Methanol as hole scavenger is found significant to restrain the oxidation of Au NRs and keeping the shape of Au nanorods. The electrochemical...
