“…2À as a Ti source can be converted to STO in situ on the TiO 2 surface. [16][17][18] More STO NCs can be produced and accumulated on the TiO 2 surface with longer conversion times and the morphologies of TiO 2 NRs cannot be maintained for 8 and 11 h, as shown in Fig. S2 (ESI †).…”

“…The length was shortened from 1.1 to 0.8 μm for TiO 2 NRs with the conversion time increasing from 3 to 5 h. Lecki, Zhang and Jing et al proposed that the TiO 2 surface can be gradually dissolved under an alkaline environment at high temperature and the generated Ti(OH) 6 2− as a Ti source can be converted to STO in situ on the TiO 2 surface. 16–18 More STO NCs can be produced and accumulated on the TiO 2 surface with longer conversion times and the morphologies of TiO 2 NRs cannot be maintained for 8 and 11 h, as shown in Fig. S2 (ESI†).…”

“…According to the XRD pattern and UV-DRS spectrum, it is known that the STOF-75 sample contains SrCO3 impurities, and its absorption is greater than that of the STOF-50 sample. Therefore, the band gap energy value of the STOF-75 sample is greater than that of the STOF-50 [15].…”

Optical response of SrTiO₃ thin films grown via a sol-gel-hydrothermal method

The polycrystalline SrTiO3 thin films were prepared by the sol-gel-hydrothermal method on glass substrates. The synthesis pathway was initiated by preparing a clear TiO2 solution using the sol-gel method. This clear solution was then deposited on a glass substrate using the dip coating technique, followed by the transformation of a thin layer of TiO2 into SrTiO3 by the hydrothermal method. The crystal structure, bond interactions, and band gap energy of SrTiO3 thin layers were characterized using X-ray Diffraction (XRD), Fourier Transform Infra-Red spectroscopy (FTIR), and UV–Vis Diffuse Reflectance Spectroscopy (UV-DRS). The XRD patterns of all SrTiO3 thin layers indicated the perovskite structure of the samples. The FTIR spectrum showed an interaction of the silanol groups on the surface of the glass substrate with Ti–O–Ti of SrTiO3 layers. The characteristics of the UV-DRS spectrum were influenced by the thickness of the SrTiO3 layer formed on the glass substrate. The findings of this work provide insights for producing SrTiO3 layers with specified thickness and morphology.

Study on the preparation, characterization, and electrocatalytic performance of Gd‐doped PbO₂ electrodes

et al. 2021

In this work, Gd-doped PbO 2 electrodes were prepared by electrodeposition procedure. In the accelerated life test, the service life of Gd-doped PbO 2 electrodes are more stable and durable. Scanning electron microscope and x-ray diffraction tests reveal that Gd-doped PbO 2 electrodes have more compact structure and finer grain size. Electrochemical measurements and fluorescence experiments show that Gd-doped PbO 2 electrodes have higher oxygen evolution overpotential, a larger electrochemically active surface area, and stronger ability to generate hydroxyl radicals. The electrocatalytic performance of the Gd-doped PbO 2 electrode for the electrochemical degradation of thiamethoxam was studied. The degradation process accorded with pseudofirst-order kinetics, with higher thiamethoxam and total organic carbon removal capabilities, as well as higher mineralization current efficiency and lower energy consumption. In the degradation process, it has favourable reusability. The experimental results demonstrate that Gd-doped PbO 2 electrodes have an excellent treatment effect and a wider application prospect in the field of pollutant degradation.
