“…It has been possible to prepare a variety of bimetallic nanostructures by using several different methods ( Feng et al, 2012 ; Lee et al, 2014 ; Zheng et al, 2020 ; Zhou L. et al, 2021 ; Zhou M. et al, 2021 ; Feng et al, 2021 ; Jiang et al, 2021 ; Skrabalak, 2021 ; Yang et al, 2021 ; Lee et al, 2022 ). Cu and Au nanostructures are excellent materials for applications in catalysis and plasmonic ( Zhang et al, 2019 ; Mi et al, 2021a ; Xin et al, 2021 ; Zhang B. et al, 2022 ; Lin et al, 2022 ). Cu nanostructures, which are valuable plasmonic materials in the visible to near-infrared region, have contributed to the development of applications in photonics, sensing, heterogeneous catalysts and imaging ( Gawande et al, 2016 ; Lee D. W. et al, 2021 ; Medvedeva et al, 2021 ).…”
