This paper represents a general study of titanate nanotubes (TiNTs) which are among the most important materials in the field of catalysis. This research work covers more than 100 publications about the formulation, characterisation and most recent applications of TiNTs. TiNTs can be prepared by different methods, namely the anodic deposition, sol-gel template synthesis and alkaline hydrothermal treatment. The present study focuses on the preparation of this tubular structure by alkaline treatment, using the latest and most recent processes that have been introduced in this method (stirring, acid nature, annealing temperature, etc). The surface properties, such as the point of zero charge (P.Z.C), acid-base nature and light absorption, of TiNTs are also evoked. In the end, some recent and important TiNTs applications in the field of renewable energies are reported (H 2 production and methanation). In addition, NO reduction, CO oxidation, photocatalysis and organic synthesis are also mentioned. Therefore, it may be said that this paper is a structured study about TiNTs for the purpose of making the reader aware of their importance, understand their synthesis, and know their scope of applications. To conclude, the most important data, acquired through various characterization techniques, are provided.[a] Dr.

“…Meanwhile, Ti-O stretching vibrations of hydrogen titanates were also detected in vibration mode at 908 cm -1 (Bavykin et al, 2006), which only found in the samples prepared at 20 and 30 h. Furthermore, in all samples, at 3210 cm -1 the board spectrums were observed indicating the presence of -OH groups in the surface, and strong absorption at 1633 cm -1 were also found which attributes to the deformation vibration of H-O-H bonds in the physically absorbed water. Another, IR absorption in the range of 1600-3600 cm -1 detected indicates the manifestation of -OH groups and H-O-H molecules that are weakly bounded in different active sites of TiO2 (Li et al, 2005;Shankar et al, 2009;Choudhury et al, 2012;Ariyanti et al, 2018).…”

“…The formation of B-TiO2 with 30 h hydrothermal treatment is due to H2Ti3O7 reorganization as a result of heat treatment and continuous water loss (Ariyanti et al, 2018;Zhu et al, 2001). Figure 3 shows the FT-IR spectra of TiO2 based nanostructures prepared at variable of times.…”

“…This method was able to convert amorphous TiO2 into nanotubes and nanoribbons with almost 100% efficiency Kasuga et al, 2005;Bavykin et al, 2006). The application of TiO2 nanoribbon varied such as the photocatalyst nanohybrid with carbon nanotubes for water splitting photoelectrochemical (PEC) enhancement (Ahmed et al, 2020); anode material in combination with SnO2 for rechargeable battery (Li et al, 2016); organic pollutant removal (Ariyanti et al, 2018Ariyanti et al, 2019.…”

TiO2 is a semiconductor material with endless potential for the development of renewable energy as well as in the environmental field application. With various methods, TiO2 nanostructures with various morphology, properties and application can be developed. In this paper, the synthesis of TiO2 based nanoribbons with high adsorption property produced by alkaline hydrothermal methods were investigated. Its morphology, crystal structure and physical properties were characterized using Scanning Electron Microscope (SEM), X-ray diffraction (XRD), Fourier-transform infrared (FTIR) and Brunauer-Emmett-Teller (BET) surface area analysis. The result shows that by controlling the hydrothermal processing time, different morphology and structures of TiO2 nanoribbons with different adsorption properties can be obtained. The nanoribbons produced via alkaline hydrothermal method has width 200-300 nm and length up to several microns. It also possesses fair adsorption capacity over dyes (Rhodamine B and Methyl orange) considering its large surface area and high pore volume.

“…The broad band at ≈3400 cm −1 corresponds to the adsorbed oxygen species (O–H) within the MIL‐125(Ti). [ 34–36 ] These spectra reveal that the TiOTi bond (643 cm −1 ) for titanium oxide and TiO (899 cm −1 ) and HOH (1628 and 2916 cm −1 ) bonds for hydrogen titanate [ 37,38 ] are generated during the pyrolysis process at the metal‐cluster decomposition temperature (300 °C). On the other hand, the carboxylate group‐related bonds of the organic linker shifted slightly to a high wavenumber, which is due to the increase in the number of unsaturated coordination site induced by metal‐cluster decomposition or the evaporation of absorbed guest molecules.…”

Design of Bronze‐Rich Dual‐Phasic TiO₂ Embedded Amorphous Carbon Nanocomposites Derived from Ti‐Metal–Organic Frameworks for Improved Lithium‐Ion Storage

Dual‐phasic (DP)‐TiO2‐based composites are considered attractive anode materials for high lithium‐ion storage because of the synergetic contribution from dual‐phases in lithium‐ion storage. However, a comprehensive investigation on more efficient architectures and platforms is necessary to develop lithium‐storage devices with high‐rate capability and long‐term stability. Herein, for the first time, a rationally designed bronze‐rich DP‐TiO2‐embedded amorphous carbon nanoarchitecture, denoted as DP‐TiO2@C, from sacrificial Ti‐metal–organic frameworks (Ti‐MOFs) via a two‐step pyrolysis process is proposed. The bronze/anatase DP‐TiO2@C nanocomposites are successfully synthesized using a unique pyrolysis process, which decomposes individually the metal clusters and organic linkers of Ti‐MOFs. DP‐TiO2@C exhibits a significantly high density and even distribution of nanoparticles (<5 nm), enabling the formation of numerous heterointerfaces. Remarkably, the bronze‐rich DP‐TiO2@C shows high specific capacities of 638 and 194 mAh g−1 at current densities of 0.1 and 5 A g−1, respectively, owing to the contribution of the synergetic interfacial structure. In addition, reversible specific capacities are observed at a high rate (5 A g−1) during 6000 cycles. Thus, this study presents a new approach for the synthesis of DP‐TiO2@C nanocomposites from a sacrificial Ti‐MOF and provides insights into the efficient control of the volume ratio in DP‐TiO2 anode architecture.
