Recently, preparation of complex nanostructures with rich function by chemical multistep methods is the hotspot of research. In this review we introduce three typical multistep methods to prepare silver nanostructures with well-controlled shapes, including the double reductant method, etching technique and construction of core-shell nanostructures. The growth mechanism of double the reductant method is that different favorable facets of silver nanocrystals are produced in different reductants, which can be used to prepare complex nanostructures such as nanoflags with ultranarrow resonant band bandwidth or some silver nanostructures which are difficult to prepare using other methods. The etching technique can selectively remove nanoparticles to achieve the aim of shape control and is widely used for the synthesis of nanoflowers and hollow nanostructures. Construction of core-shell nanostructures is another tool to control shape and size. The three methods can not only prepare various silver nanostructures with well-controlled shapes, which exhibit unique optical properties, such as strong surface-enhanced Raman scattering (SERS) signal and localized surface plasmon resonance (LSPR) effect, but also have potential application in many areas.<\/jats:p>","DOI":"10.3390\/s140405860","type":"journal-article","created":{"date-parts":[[2014,3,25]],"date-time":"2014-03-25T12:33:44Z","timestamp":1395750824000},"page":"5860-5889","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":72,"title":["Synthesis of Silver Nanostructures by Multistep Methods"],"prefix":"10.3390","volume":"14","author":[{"given":"Tong","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Electronic Science and Engineering, Southeast University, and Key Laboratory of Micro-Inertial Instrument and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"},{"name":"Suzhou Key Laboratory of Metal Nano-Optoelectronic Technology, Suzhou Research Institute of Southeast University, Suzhou 215123, China"}]},{"given":"Yuan-Jun","family":"Song","sequence":"additional","affiliation":[{"name":"School of Electronic Science and Engineering, Southeast University, and Key Laboratory of Micro-Inertial Instrument and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"},{"name":"Suzhou Key Laboratory of Metal Nano-Optoelectronic Technology, Suzhou Research Institute of Southeast University, Suzhou 215123, China"},{"name":"School of Chemistry and Chemical Engineering, Southeast University, Nanjing 211189, China"}]},{"given":"Xiao-Yang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Electronic Science and Engineering, Southeast University, and Key Laboratory of Micro-Inertial Instrument and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"},{"name":"Suzhou Key Laboratory of Metal Nano-Optoelectronic Technology, Suzhou Research Institute of Southeast University, Suzhou 215123, China"}]},{"given":"Jing-Yuan","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Electronic Science and Engineering, Southeast University, and Key Laboratory of Micro-Inertial Instrument and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"},{"name":"Suzhou Key Laboratory of Metal Nano-Optoelectronic Technology, Suzhou Research Institute of Southeast University, Suzhou 215123, China"}]}],"member":"1968","published-online":{"date-parts":[[2014,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4834","DOI":"10.1016\/j.polymer.2011.08.021","article-title":"A versatile hydrogel template for metal nano particle preparation and their use in catalysis","volume":"52","author":"Butun","year":"2011","journal-title":"Polymer"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"203","DOI":"10.1016\/j.matchemphys.2011.01.060","article-title":"Role of pH in the synthesis of 3-aminopropyl trimethoxysilane stabilized colloidal gold\/silver and their alloy sols and their application to catalysis","volume":"127","author":"Harish","year":"2011","journal-title":"Mater.
