“…Whereas, nanotubes possess high specic surface area and hollow morphology and therefore, it is widely researched in many areas, including chemical catalysis, photocatalysis, electrocatalysis, sensors, and lithium batteries compared to other regular forms (nanoribbon, nanowire, nanosheet). 17,18 Moreover, the characteristic TiO 2 exhibit a bifunctional property, i.e., Lewis acid and base attributed to the lattice O À and Ti + ions, and therefore, it has been extensively applied for chemical reactions. 19,20 For instance, Lanziano et al demonstrated the catalytic performance of TiO 2 (supercial area of 128 m 2 g À1 ) on glucose to fructose conversion in aqueous medium, but only 12% wt fructose yield could be obtained at 120 C claiming limited catalytic activity.…”

“…The existence of Ti-OH and structural O 2 2− in sample (a) confirmed that sample (a) contains Na 2 Ti 3 O 7 and titanium peroxide. The presence of Na1s spectra at 1071.9 eV indicated the existence of Na-O owing to Na 2 Ti 3 O 7 [30]. The XPS results provided evidence on the existence of titanium peroxide in sample (a).…”

Na2Ti3O7/titanium peroxide composites (TN-TP) were successfully prepared with the reaction of Ti foils, NaOH, and H2O2at 60°C for 24 h in water bath. The Na2Ti3O7appeared as nanorods in composites. Water bath temperature, water bath time, and the concentration of H2O2and NaOH were crucial. The reaction mechanism was proposed. TN-TP was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and thermogravimetric and differential scanning calorimetry (TG-DSC). TN-TP was a mesoporous material and exhibited stronger adsorption capability for neutral red (NR), malachite green (MG), methylene blue (MB), and crystal violet (CV) than pure Na2Ti3O7and pure titanium peroxide, and the saturated adsorption capacities were 490.21, 386.13, 322.81, and 292.74 mg/g at 25°C, respectively. It was found that the pseudo-second-order kinetic model and the Langmuir model could well describe the adsorption kinetic and isotherm of cationic dyes studied. The results of this work are of great significance for environmental applications of TN-TP as a promising adsorbent material for dyeing water purification.

“…Another study regarding the titanium as catalyst support was conducted by Takase et al (2014) whereby the modified C4H4O6HK catalyst with the presence of titanium had granular and porous structures with high basicity and superior catalytic performance of 90.1 % of biodiesel yield at 30 minutes of reaction. Marciniuk et al (2014) meanwhile prepared sodium titanate catalyst for the transesterification reaction under mild conditions. The study offers better light regarding titanium as catalyst support in the transesterification reaction.…”

Biodiesel is a promising alternative for conventional diesel fuel due to the unsustainable feature of the resources and unstable price of the fuels. However, the production cost is higher compared to the conventional ones and is significantly contributed from the feedstock. Realizing that a large portion of used cooking oil (UCO) is generated daily, this review aims to investigate and explore the production of biodiesel from UCO. In the production reaction process, undoubtedly, the catalyst plays an important role. It has been shown that calcium oxide (CaO) is one of the best heterogeneous basic catalysts in the transesterification reaction for biodiesel production. However, the catalyst has a low surface area which restricts the active basic sites to disperse on the catalyst surface. Moreover, CaO catalyst faces leaching problem, poor stability, and porosity which hinder its catalytic activity and reusability. Therefore, in this study, it is aimed to review the potential of titanium as a support catalyst to modify CaO supported titanium with a mesoporous structure (mesoporous calcium titanate) by a sol-gelhydrothermal method to overcome the limitations of CaO catalyst.
