Templated bipolar electrolysis for fabrication of robust Co and Pt nanorods

Abstract

The migration of metal ions into a nanoporous electrode was controlled using an electrophoretic effect under the influence of an external electric field based on the concept of bipolar electrochemistry. Robust, uniform and well-aligned arrays of Co and Pt nanorods were observed to form vertically against the electrode.

Dendritic Organic Electrochemical Transistors Grown by Electropolymerization for 3D Neuromorphic Engineering

“…Electropolymerization of PEDOT from EDOT monomers has been largely investigated as a bottom‐up technique for material engineering. [ 17 ] This technique results in a large panel of material properties depending on the oxido‐reduction reactions involved in the electropolymerization, electrolyte composition, and electrical parameters use to drive the electropolymerization's reaction. More recently, bipolar electropolymerization of PEDOT was proposed for conductive fibers engineering.…”

Bipolar Electrochemistry: A Powerful Tool for Electrifying Functional Material Synthesis

“…We have also designed the electrophoresis-assisted synthesis of densely packed metal nanorods in conjunction with bipolar electrochemistry (Figure ). Porous anodic aluminum oxide (AAO) membranes are a popular template for the fabrication of 1D nanostructures by electrodeposition. In AAO membranes, however, hollow materials tend to be obtained due to the limited supply of ions or monomers, which results in mechanical weakness of the 1D structures.…”

“…Bipolar electrochemistry is a relatively old technology that has recently garnered renewed attention because of the interesting features of BPEs because (i) the wireless nature of a BPE is useful for sensors and material synthesis, (ii) the gradient potential distribution on BPEs is a powerful tool for the preparation of gradient surfaces and materials, and (iii) electrophoresis is available for effective electrolysis …”

Hydrogen generation from ammonia electrolysis on bifunctional platinum nanocubes electrocatalysts

“…Since both AEOR and HER are typical structure-sensitive reactions, the control of morphology and/or surface crystalline orientation is an efficient strategy for electroactivity enhancement. Among various Pt nanostructures with different morphologies, such as nanochains [16] , nanowires [17] , tetrahedral [18] , cuboctahedra [19] , nanorods [20] , nanodendrites [21] , nanosheets [22] , and nanocubes [23][24][25] . Pt nanocubes (Pt-NCs) with {100} facets are of especial interest for both AEOR and HER.…”
