Reactions of titanium oxides with water molecules. A matrix isolation FTIR and density functional study

Shao, Limin,Zhang, Luning,Chen, Mohua,Lu, Hao,Zhou, Mingfei

, p. 178 - 184 (2001)

Reactions of titanium dioxides with water molecules have been studied by matrix isolation infrared and density functional theoretical calculations. In solid argon, titanium dioxide molecules reacted with water to form OTi(OH)2 molecules spontaneously on annealing. The potential energy surface along the TiO2+H2O→OTi(OH)2 reaction path was calculated. Although titanium dioxide-water complex was predicted to be stable, this complex was not observed due to low energy barrier and high exothermicity for the hydrolysis reaction. Evidence is also presented for the formation of OTi-OH2 complex.

Efficacy of photodynamic therapy using TiO2 nanoparticles doped with Zn and hypericin in the treatment of cutaneous Leishmaniasis caused by Leishmania amazonensis

Arenas Velásquez, Angela Maria,Fontana, Carla Raquel,Garcia, Claudia,Graminha, Marcia Aparecida Silva,Pati?o Linares, Irwin Alexander,Sepúlveda, Alex Arbey Lopera,de Almeida, Leticia

, (2020)

Since Leishmania parasites exhibit resistance outbreaks to drugs conventionally used in medical treatments, research of new antileishmanial compounds or alternative treatment therapies are essential. A focus of interest has been the implementation of light-based therapies such as photodynamic therapy, where inorganic compounds such as titanium dioxide have shown promising results as drug delivery carriers. In this work, nanoparticles of TiO2 doped with Zn (TiO2/Zn) were synthesized through solution combustion route and with hypericin (HY) in order to enhance its photodynamic activity in the visible light region. Scanning (SEM) and transmission (TEM) electron microscopy analyses showed particles of (TiO2/Zn) with sizes smaller than 20 nm and formation of aggregates smaller than 1 μm, whilst electron diffraction spectroscopy (EDS) analysis ensured the presence of Zn in the system. The association of the TiO2/Zn with HY (TiO2/Zn-HY) was further confirmed by fluorescence spectrometry. Measurements of its cellular uptake showed the presence of smaller molecules into promastigotes after 120 min incubation. TiO2/Zn-HY showed good antileishmanial activity (EC50 of 17.5 ± 0.2 μg mL?1) and low cytotoxicity against murine macrophages (CC50 35.2 ± 0.3 μg mL?1) in the visible light (22 mW cm-2; 52.8 J cm-2). Moreover, in the in vivo analysis, TiO2/Zn-HY decreased the parasite load of L. amazonensis - BALB/c infected mice by 43% – 58% after a combination of blue and red light presenting 22 mW cm-2 of intensity and 52.8 J cm-2 of fluency delivered. All together, these data indicate a new combined system of nanoparticles associated with a photosensitizer and PDT as alternative to amphotericin B for the treatment of cutaneous leishmaniasis.

Metatitanic acid pseudomorphs after titanyl sulfates: Nanostructured sorbents and precursors for crystalline titania with desired particle size and shape

Klementova, Mariana,Motlochova, Monika,Boha?ěk, Jaroslav,Kupcí k, Jaroslav,Palatinus, Lukas,Plizingrova, Eva,Szatmary, Lorant,Sǔbrt, Jan

, p. 6762 - 6769 (2017)

A new preparation method for the synthesis of TiO2 microrods in aqueous media starting with solid hydrated titanyl sulfate crystals with defined morphology is presented. The method is based on the extraction of sulfate ions from the crystals and their replacement with hydroxyl groups in aqueous ammonia solution leaving the Ti?O framework intact. The particle size and morphology of the starting hydrated titanyl sulfate is closely preserved in the pseudomorphs of amorphous metatitanic acid including such details like the layered structure of the original hydrated titanyl sulfate crystals. When annealed up to 1200 °C, the rod-like morphology of particles is retained, while the phase composition changes to anatase/rutile. The rod-like particles of metatitanic acid possess excellent sorption properties toward radionuclides. The mechanism of pseudomorph formation is discussed based on the structures of the precursors, including the hitherto unknown structure of titanyl sulfate dihydrate determined by electron diffraction tomography.

Preparation of lithium titanate nanoparticles assisted by an ion-exchange process and their electrochemical performance as anode materials for Li-ion batteries

Hong, Hye-Jin,Kim, Byung-Su,Kwon, Sukcheol,Lee, Sung-Yun,Park, In-Su,Yoon, Sukeun

, (2021/08/03)

Spinel-structured lithium titanate (Li4Ti5O12, LTO) has received broad attention as a next-generation anode material for Li+-ion batteries because of its excellent safety and long cycle life. However, calcination at the high temperatures (>800 °C) is necessary to obtain spinel-phase LTO. This interferes the synthesis of LTO particles as nano-sized material which is advantageous for electrochemical performance. In this study, spinel-structured LTO nanoparticles were synthesized via an ion-exchange process in conjunction with a mild calcination temperature (600 °C). First, Li2TiO3 was prepared by calcination of a LiOH?H2O/TiO2 (atomic ratio Li/Ti = 2) mixture at 600 °C. Second, the Li+ ions of the layered Li2TiO3 were partially exchanged with H+ ions in HCl solution, resulting in the synthesis of HxLi2?xTiO3 (0 2TiO3 particles and the calcination temperature on the phase composition of the final product. The phases in the final product are sensitively determined by the conditions used in the ion-exchange reaction and subsequent calcination. Under the optimized conditions, spinel phase dominant LTO particles are synthesized by calcination at a low temperature (600 °C). Because of the mild calcination temperature, the crystal size and secondary particle size of the spinel-structured LTO are 23.9 nm anda high initial discharge capacity of 165.3 mAh g?1 at 1 C, excellent cyclic stability, and superior rate performance when used as an anode material in a Li+-ion battery. Therefore, the suggested synthetic process is advantageous for the production of nanostructured LTO electrode materials.
