Here, we report the fabrication of self-organized titania (TiO(2)) nanotube array supercapacitor electrodes through controlled phase transformation of TiO(2), with aerial capacitances as high as 2.6 mF cm(-2), which far exceeds the values so far reported in the literature. The role of phase transformation in the electrochemical charge-discharge behaviour of nanocrystalline TiO(2) nanotubes is i...

Anodic formation of titania nanowires has been interpreted using a bamboo-splitting model; however, a number of phenomena are difficult to explain with this model. Herein, transition from nanotubes to nanowires is investigated by varying the anodizing conditions. The results indicate that the transition requires a large number of hydrogen ions to reduce the passivated area of tube walls, and th...

Titania nanotubes (TNT) prepared by anodization of Ti foils were used for water splitting in a standalone cell. The concentration polarization between the anode side (1M NaOH) and cathode side (0.5 M H2SO4) ensured that the water splitting reaction could take place with no external bias and separate H2 and O2 evolution could be achieved. The destructi...

Recently, titania nanotubes (TNTs) have been extensively studied because both their functional properties and highly controllable morphology make them important building blocks for understanding nanoscale phenomena realizing devices. Compared with sol–gel template-assisted methods, electrochemical anodization is a simple, cost-effective, low-temperature technique offering additional advantages ...

Single atom (SA) catalysis, over the last 10 years, has become a forefront in heterogeneous electrocatalysis, and most recently also photocatalysis. Most crucial when engineering SA catalyst/support system is creation of defined anchoring points on support surface to stabilize reactive sites. Here, so far unexplored but evidently very effective approach trap SAs broadly used photocatalyst platf...
