“…Generally, the incorporation of pulses in applied current is a manipulation reported to improve the growth and coating characteristics such as geometry, porosity, surface defects, and crystal orientation. 81,82 Additionally, the inclusion of pulses has been reported to bring out uniformity and compactness with increased adhesive strength in comparison to coatings deposited under a direct continuous current. 83 Pulses in current favor enhancement in nucleation rate over growth assimilation with refinement in grain size and roughness.…”

“…This anodization process has three distinct phases in a single procedure. [76,77] In the first phase, [75] with permission from Springer conventional anodization was conducted at 60 V for the duration of 8 min; the second phase witnessed a sudden withdrawal of applied potential for a period of 10 min and in the final phase anodization was conducted from where it was stopped for a period of 1 h. The current density-time plot and the highly ordered TiO 2 NTs obtained in pause anodization are displayed in Figure 16.…”

“…[168][169][170] A pause in the anodization voltage assisted in an easy removal of top layer along with the debris. [76,77] Pulse anodization aided in the retardation of preferential etching of the oxide layer [80] and the thickening and thinning of tube walls could be manipulated by applying a pulse in the negative region. [79] Polygonal ring structure is obtained at the second layer when the voltage is stepped up and the thinning of the barrier layer also takes place.…”

Over the past couple of decades (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020), titania (TiO 2 ) nanotubes (NTs) have been prepared by anodization techniques. The architecture of TiO 2 NTs is predominantly dependent on the potential, current density, electrolyte and time, in addition to other few minor factors. This review is about the state-of-the-art formation of TiO 2 NTs involving anodization technique. In fact, the principal motive is to briefly discuss the slight variations involved within the anodization technique in terms of applied potential and/or applied current density and the resultant outcome. An initial overview of the technique is given so as to understand the beauty of the reactions when variations are incorporated. A minute alteration in the conventional anodization technique results in the formation of highly different morphological features. There are about 30 different miniscule modifications in the anodization processes that have been reported, thus, far. The review primarily introduces and outlines the various anodization techniques involved in growing TiO 2 NTs and the consequent variations arising from these introduced variations. This review is a tribute to the bountiful and fruitful researches based on modifying anodization that was conducted in the recently passed bi-decades.

“…However, it is vital to consider that, in comparison to aqueous electrolytes, these electrolytes are more costly and less eco-friendly. In addition, in recent years various publications [14][15][16][17][18][19][20][21][22] have reported certain problems related to the coating regularity and packing of TiO 2 nanotubes made in organic solutions, for example, delamination, cracks, different spaces among nanotubes, and coral-like structures.…”

Titanium surfaces were anodized to create nanotube structures utilizing an aqueous electrolyte made of xanthan gum (XG) and sodium fluoride. The purpose of employing this type of anodizing solution was to investigate the impact of XG addition on the morphology and organization of nanotubes. As far as we know, this is the first time that TiO2 nanotubes, made using aqueous electrolytes with XG as an additive, have been reported. The organization of the nanotubes was measured using the regularity ratio (RR) from the fast Fourier transformation (FFT) pictures. Contrary to the nanotubes formed in aqueous solutions without XG, the addition of XG to the aqueous electrolyte improved the nanotube organization, with no effect on packability. Based on the findings of this experimental work, organized and homogeneous nanotubular structures might be produced utilizing an inexpensive and non-toxic aqueous electrolyte.
