Preparation and photocatalytic activity of TiO2 nanotube arrays prepared on transparent spinel substrate

The Anodization of Thin Titania Layers as a Facile Process towards Semitransparent and Ordered Electrode Material

“…Photoactive materials consisting of TNTs grown on TCO have been investigated to address global challenges such as organic pollutant degradation [ 58 ], solar-to-electricity conversion [ 30 ], and solar-to-hydrogen conversion [ 59 ]. The large band gap of TiO 2 , i.e., 3 eV for rutile and 3.2 eV for anatase phase, is the fundamental drawback of TNTs-based materials.…”

“…The photocatalytic degradation of Rhodamine B (RhB) dye by photoelectrodes consisting of TNTs grown on transparent substrates such as ceramic spinel (MgAl 2 O 4 ) and polymeric Kapton film via electrochemical anodization, has been investigated by Petriskova et al [ 58 ]. They compared the performance of the fabricated active materials to those obtained by using Si wafer or Ti foil as substrates.…”

Preparation of heterostructured TiO2/MoS2 for efficient photocatalytic rhodamine B degradation

“…Additionally, pure TiO 2 usually did not have a high charge separation rate, and therefore illustrated relatively low photocatalytic activity. Thus, many research studies have been conducted to settle these inadequacies including tuning the particle size, 7 crystallinity and morphologies (nanotubes 8 in 1D, nanosheets 9 in 2D and microspheres 10 or nanoflowers 11 in 3D), and constructing heterostructured materials, [12][13][14] which have resulted in the promotion of the photocatalytic performance. Among these nanostructures, heterostructures like core-shell structures 15 with a large specific surface area and matched energy levels have attracted great attention.…”

Incorporation of Ions into Nanostructured Anodic Oxides—Mechanism and Functionalities

“…For example, copper anodizing contributes to such important applications as CO 2 electrochemical reduction [24], methanol fuel cells [25], photocatalytic water splitting [26] and microplastic decomposition [27]. Anodic titania is used in such important aspects as photocatalytic water splitting [28], hazardous compounds neutralization (e.g., Bisphenol A and Rhodamine B [29], or chromates [30]) and microplastic decomposition [31]. Moreover, anodic titania is also gaining the attention of researchers as a drug-releasing platform [32] and sensor [33].…”
