Rational Design of Metal Nanoframes for Catalysis and Plasmonics

Abstract

Recently, metal nanoframes have received increased attention due to their unique spatial and physicochemical, e.g., catalytic and plasmonic properties. So far, a variety of synthetic procedures have been developed to fabricate metal nanoframes with different shapes, sizes and compositions. Typical synthesis of metal nanoframes involves two stages: 1) formation of solid nanocrystals and 2) hollowing out the interiors and side faces. In this review, solution-phase synthetic strategies are summarized, based on galvanic replacement reactions, oxidative etching, the Kirkendall effect, electrodeposition, and template-assisted growth, as well as one-pot synthesis. Their potential applications in catalysis and optical sensing are overviewed as well.

Engineering Ordered and Nonordered Porous Noble Metal Nanostructures: Synthesis, Assembly, and Their Applications in Electrochemistry

“…Upon addition of specific surfactants, it is possible to fabricate metallic hollow nanostructures when all the reactants are added to the container at the same time. 254 Of these hollow nanomaterials constructed through a one-pot approach, Pt−Cu alloy with hollow nanostructures have been widely investigated. Novel cubic PtCu 3 nanocages were prepared through dissolution of H 2 PtCl 6 ·6H 2 O, Cu(acac) 2 , and CTAB in OAm, with subsequent solvothermal process.…”

Many review papers have provided insights into this field from diverse perspectives: synthetic strategies, [10][11][12][13][14][15][16][17] structural diversity, [18][19][20][21][22][23] product compositions, [24][25][26][27] and potential applications.…”

The alloying effect and AgCl-directing growth for synthesizing a trimetallic nanoring with improved SERS

“…16 Noble nanostructures with exposed high-indexed facets have excellent catalytic performance. [18][19][20][21][22][23][24][25] Among them, seeded growth and selective etching are very fascinating owing to their multi-functions in generating nanostructures. So far, lots of protocols including seeded growth, template, selective etching (galvanic etching or others) have been widely used.…”
