Insertion of nanostructured titanates into the pores of an anodised TiO₂ nanotube array by mechanically stimulated electrophoretic deposition

Abstract

TiO2 nanotube (TiO2NT) surfaces can achieve a high area surface and enhanced electrocatalytic properties.

Processes associated with ionic current rectification at a 2D-titanate nanosheet deposit on a microhole poly(ethylene terephthalate) substrate

“…Titanate nanosheet material was synthesised as described previously by Sasaki et al [21] and by Harito et al [49,50]. Hydrochloric acid, sodium chloride, potassium chloride, lithium chloride, ammonium chloride, tetrabutylammonium chloride, magnesium chloride, calcium chloride, sodium hydroxide, sodium nitrate, sodium perchlorate and sodium sulphate were obtained in analytical grade from Sigma-Aldrich or Fischer Scientific and used without further purification.…”

Developments in electrode design: structure, decoration and applications of electrodes for electrochemical technology

“…This surface was prepared by incorporation of titanates into an anodized microporous TiO 2 array on a titanium foil via electrophoresis. Further studies have explored improved experimental conditions, and the use of in‐situ mechanical abrasion of the surface to promote insertion of nanotubes into the closed packed hexagonal porous array …”

“…Further studies have explored improved experimental conditions, 28 and the use of in-situ mechanical abrasion of the surface to promote insertion of nanotubes into the closed packed hexagonal porous array. 29 The decoration of electrode surfaces 3D printing and computational approaches to cell and electrode design Traditionally, a workshop approach to flow cell production might involve machining of polymer sheet, typically 1-10 mm thick, to produce the required rectangular flow channel and manifolds, typically by milling. Such machining to remove material tends to be slow, costly and tedious, which has encouraged the use of moulding then CNC machining and fast prototyping using additive techniques, especially 3D printing, over the last 30 years.…”

“…Uma estratégia para facilitar a inserção de nanoestruturas no interior de materiais complexos como os poros dos nanotubos de TiO2 é realizar uma perturbação física de maneira controlada juntamente com a técnica de EPD.Nesse contexto, uma maneira eficiente que pode promover a inserção de titanatos no interior de nanotubos de TiO2 é a utilização de sistemas eletroquímicos adaptados que utilizam movimentação mecânica controlada,106 conforme representando esquematicamente TiNT) no interior de estruturas de TiO2NT utilizando técnicas de fácil manuseio como a EPD.Com relação a aplicação, os titanatos têm sido utilizados eficientemente em diversas áreas como em baterias e células combustível, supercapacitores e células solares 90. Alguns autores têm estudado também a aplicação de titanatos na degradação fotocatalítica de poluentes orgânicos.…”
