“…They were obtained at static potentials between 1.5 and 2.7 V with assistance of PEG [66]. PEG also plays an important role in controlling the growth morphology of the silver particles on glassy carbon electrode (GC), dendritic Ag NPs can only be formed with higher concentration of PEG [69]. While in AgNO 3 -SDS aqueous solution, silver dendrites were obtained on titanium substrate [68].…”

This article reviews recent advances in the shape-controlled synthesis routes of hierarchical Ag dendritic nanostructures. Various fabricated techniques, with or without templates or surfactants, electrochemical method and sonochemical, microwave or photochemical assisted synthesis method, can be amazingly effective in the dendritic Ag nanostructures synthesis, if synthetic parameters are carefully selected. The involved synthesis mechanism are discussed in order to control the limited factors along the fabricated progress efficiently and then to find new synthetic means. Also, the blemish of the above synthesis routes that hinders the practical application is pointed out to inspire the future research.

“…Examples of fabrication method are sonochemical method, solvothermal method, aqueous chemical method, electrodeposition method, electroless deposition method, replacement action and template assisted method. [1][2][3][4][5]8,12,13 Replacement action was done by immersing zinc or copper foil in a solution which contains silver ions, and the final product can be removed from the substrate. 13,14 For template assisted method, porous alumina, carbon nanotubes and mesoporous silica have been employed as a template to synthesize Ag nanostructures.…”

Highly-ordered titanium dioxide nanotubes array was prepared in fluoride based electrolyte and was subsequently deposited with silver nanoparticles and decorated by silver dendritic structures in silver ions-rich ethanolic electrolyte through conventional two-electrode configuration electrochemical method. The nanoparticles conglomerated at the surface of titanium dioxide nanotubes to form a hierarchy dendritic nanostucture, analogous to a structure consists of a trunk with branches and leaves, through the diffusion-limited aggregation mechanism and oscillatory character in nucleation kinetics. Structural investigation by X-ray diffraction measurements revealed that titanium dioxide nanotubes are comprised of multiple anatase and rutile phases. The finding is aligned with the observation of active anatase and rutile Raman modes through Raman measurements. In comparison of silver loaded titanium dioxide nanotubes to unloaded nanotubes in Raman measurements, surface-enhanced Raman scattering effect was demonstrated by silver incorporated samples whereby the Raman signal is intensified to more than sixfold in certain sample.

The efficiency and accuracy of material fabrication are closely related to the quantity and quality of material structures/properties, which usually involves multiple parameters with high cost and time waste. Here, an intelligent and high‐throughput platform is developed to regulate multiple electrodeposition parameters of a microdroplets array for controlling and predicting nanostructures. On such platform, the minipillars can anchor the microdroplets as individual deposition reactors, and the electrodes are integrated on one side to achieve high‐throughput and simultaneous electrochemical fabrication. Such integrated and intelligent platform has been employed to investigate gold nanostructures via regulating the deposition parameters (time, potential, HAuCl4 concentration, Cl−/SO42− concentration in electrolyte, temperature, and humidity), and to establish the database of electrochemically‐fabricated gold nanostructures for guiding the design and fabrication of specific gold nanostructures. It is believed that such platform can act as a pioneer to promote the development of materials science by coupling intelligence technology with nanomaterial fabrication.
