As one unique group of two-dimensional (2D) nanomaterials, 2D metal nanomaterials have drawn increasing attention owing to their intriguing physiochemical properties and broad range of promising applications. In this Review, we briefly introduce the general synthetic strategies applied to 2D metal nanomaterials, followed by describing in detail the various synthetic methods classified in two categories, i.e. bottom-up methods and top-down methods. After introducing the unique physical and chemical properties of 2D metal nanomaterials, the potential applications of 2D metal nanomaterials in catalysis, surface enhanced Raman scattering, sensing, bioimaging, solar cells, and photothermal therapy are discussed in detail. Finally, the challenges and opportunities in this promising research area are proposed.

“…It is worth noting that the prepared Ag NPLs have a significant activity in the ECD, whereas these nanoplates were inactive in a simple bath. 13 Previously, we examined 2,2 -bipyridyl in an ECD bath to successfully activate polycrystalline Ag nanoparticles as an ECD catalyst. 8 In this study, the values of A of all NPLs were determined.…”

“…The ESA is an essential parameter to compare the activities of different electrochemical catalysts. 12 The purpose of the present study is to demonstrate the use of the ESA in order to estimate the activity of Ag nanoplates (NPLs), which have never been previously used for ECD 13 and which are herein tested as a new catalyst in an ECD bath containing 2,2 -bipyridyl. Based on the consideration of the ESA, an electrochemical quartz crystal microbalance (EQCM) measurement was performed to determine the specific activity of Ag NPLs on the deposition kinetics.…”

Electrochemical surface areas (ESAs) were used to estimate the specific activities of different-sized Ag nanoplates (NPLs), which were used as novel catalysts for electroless copper deposition (ECD). Based on the consideration of ESAs and deposition kinetics measured using an electrochemical quartz crystal microbalance, the mean specific activities of NPLs with sizes of 74 nm, 117 nm, and 162 nm were determined to be 0.107, 0.250, and 1.017 mg • cm −2 , respectively. The largest NPLs showed the highest activity. Simultaneously, in the Tafel plot normalized to the ESA, the specific current density corresponding to 74 nm < 117 nm < 162 nm NPLs for formaldehyde oxidation in the high overpotential region was determined. This anodic reaction activated with various NPLs could thus be the rate-determining step in ECD. Additionally, an untypical open circuit potential curve containing two mixed potentials for two period depositions-Cu deposition on Ag NPLs and Cu on the deposited Cu layer-was observed. In the intended application, conductive Cu patterns on a flexible polyimide film using Ag NPL ink of 2.5 wt% solid content were successfully fabricated by inkjet printing combined with catalyzed ECD.
