Electrochemistry of titanium dioxide: some aspects and highlights

Abstract

Selected problems of electrochemical synthesis, characterization and applications of titanium dioxide are reviewed. These issues have attracted considerable attention from addressing purely academic questions up to promising applications in devices for energy storage and energy conversion.

Graphene-based cathodes for liquid-junction dye sensitized solar cells: Electrocatalytic and mass transport effects

“…The titania photoanode has been studied thoroughly, ranging from investigation of single crystals [15,38] to advanced organized nanostructures [9,39]. Usually, the nanocrystalline TiO 2 (anatase) is deposited on transparent oxides (TCO), such as FTO or indium-tin oxide (ITO) serving as current collectors.…”

TiO2 Nanotube Arrays Grafted with MnO2 Nanosheets as High-Performance Anode for Lithium Ion Battery

“…Titanium dioxide (TiO 2 ) has attracted a lot of attention among transition metal oxides as active anode material in LIBs in virtue of its attractive properties including low cost, environmental friendliness, increased safety for the higher Li-insertion potential (1.6-1.8 V vs Li + /Li) compared to commercialized carbon (graphite) materials, and low volume expansion during charge/discharge processes [27][28][29][30]. Unfortunately, in comparison to conventional anode materials, TiO 2 has a relatively low theoretical capacity of around 335 mA h g À1 and intrinsically slow transport kinetics for both electrons and Li ions, which prevent this material from optimal electrochemical performance [31][32][33].…”

One-Dimensional Titanium Dioxide Nanomaterials: Nanotubes

“…764,765 Generally, carbonaceous electrodes (e.g. graphite and its lithiated form) are the most widely used material in rechargeable Li-ion batteries due to their high theoretical capacitance (372 mAh/g), low lithiation potential (~ 0.1 V vs. Li/Li + ), and good electric conductivity, which lead to a large potential difference between anode and cathode.…”
