“…In most cases, a functional material containing pH sensitive components is applied to the surface of an appropriate sensor substrate through a variety of methods that include: Adsorption/monolayer, [ 39,48 ] polymer fi lms, [ 36 ] screen printed inks, [ 35,38,40,47 ] covalent attachment, [ 46,47 ] or electrodeposition. [ 32,33,37,[42][43][44]50 ] Screen printed electrochemical sensors have been designed specifi cally for wound pH monitoring applications and shown to be a versatile addition. [ 16 ] Rather than relying on potentiometric detection methodologies, they have exploited voltammetric scanning (typically using square-wave voltammetry) in which an endogenous biomarker such as uric acid (which is ubiquitous within most fl uids) is oxidized.…”

The pH of wound fluid has long been recognized as an important diagnostic for assessing wound condition, but as yet there are few technological options available to the clinician. The availability of sensors that can measure wound pH, either in the clinic or at home could significantly improve clinical outcome - particularly in the early identification of complications such as infection. New material designs and electrochemical research strategies that are being targeted at wound diagnostics are identified and a critical overview of emerging research that could be pivotal in setting the direction for future devices is provided.

“…TiO 2 NTs can be produced with adjustments of electrolyte composition, applied potential, and anodization time. Due to their unique properties, TiO 2 NTs have been used in many applications such as in photo(electro)catalysis [4,5,65,66], sensors [67,68], biosensors [69], dye-sensitized solar cells [70,71], hydrogen generation by water photoelectrolysis [72][73][74], photocatalytic reduction of CO 2 [58,75], and biomedical-related applications [76,77]. Table 2 illustrates some works aimed at nanostructured materials applied in the treatment of endocrine disruptors, pharmaceutical compounds, aromatic amines, ammonia, and sunscreen compounds.…”

The great versatility of semiconductor materials and the possibility of generation of electrons, holes, hydroxyl radicals, and/or superoxide radicals have increased the applicability of photoelectrocatalysis dramatically in the contemporary world. Photoelectrocatalysis takes advantage of the heterogeneous photocatalytic process by applying a biased potential on a photoelectrode in which the catalyst is supported. This configuration allows more effectiveness of the separation of photogenerated charges due to light irradiation with energy being higher compared to that of the band gap energy of the semiconductor, which thereby leads to an increase in the lifetime of the electron-hole pairs. This work presents a compiled and critical review of photoelectrocatalysis, trends and future prospects of the technique applied in environmental protection studies, hydrogen generation, and water disinfection. Special attention will be focused on the applications of TiO 2 and the production of nanometric morphologies with a great improvement in the photocatalyst properties useful for the degradation of organic pollutants, the reduction of inorganic contaminants, the conversion of CO 2 , microorganism inactivation, and water splitting for hydrogen generation.

“…In recent years, TiO 2 nanotube arrays (TNAs) have attracted significant scientific and technological interest due to their unique properties, such as large specific surface area, high adsorption ability and excellent photoelectrochemical activities, which have led to wide use of these materials in many fields including solar cells [1][2][3], hydrogen generation [4], sensors [5][6][7], photocatalysis [8][9][10], pollutant degradation [11] and bio-applications [12,13]. To obtain suitable TNAs, several technical routes have been explored to prepare TNAs including sol-gel [14], template [15], hydrothermal synthesis [16], seeded growth [17], and electrochemical anodization methods [18].…”

Controllable synthesis of well-ordered TiO2 nanotubes in a mixed organic electrolyte for high-efficiency photocatalysis

Well-ordered TiO 2 nanotube arrays (TNAs) were fabricated by electrochemical anodization in a mixed organic electrolyte consisting of ethylene glycol and glycerol. The morphology, structure, crystalline phase, and photocatalytic properties of TNAs were characterized by using TEM, SEM, XRD and photodegradation of methylene blue. It was found that the morphology and structure of TNAs could be significantly influenced by the anodization time and applied voltage. The obtained tube length was found to be proportional to anodization time, and the calculated growth rate of nanotubes was 0.6 m/h. The microstructure analysis demonstrated that the diameter and thickness of the nanotubes increased with the increase of anodization voltage. The growth mechanism of TNAs was also proposed according to the observed relationship between current density and time during anodization. As expected, the obtained TNAs showed a higher photocatalytic activity than the commercial TiO 2 P25 nanoparticles.TiO 2 nanotube arrays (TNAs), anodization, organic electrolytes, photocatalysis
