“…The samples were collected after irradiation at regular intervals and the UV-visible absorption spectra analyzed of all the collected samples. The initial concentration (C 0 ) of dyes (i.e., MO, CV, and MB) solution and the concentration at reaction time t (C t ) were evaluated to measure the percentage of dye removal using the below equation [ 39 ].

The preparation of metal organic frameworks (MOFs) has come to the forefront in recent years because of their outstanding physical and chemical properties. Many MOFs such as Zn, Co, Ni, Fe, and Ag, etc., have been successfully synthesized. In this work, we followed the solvothermal assisted route to synthesize Ag-MOF (abbreviated as AMOF) nanosheets and then applied them as a photocatalyst to remove different organic pollutants, namely methyl orange (MO), crystal violet (CV), and methylene blue (MB). Chemical composition, optical properties, morphology, and microstructural analysis were analyzed using XPS, UV-visible spectrophotometer, FESEM, TEM, and EDS, respectively. The structural properties of AMOF nanosheets were studied by X-ray diffraction (XRD). Nitrogen adsorption and desorption isotherm analysis were utilized to evaluate the specific surface area and pore size of the AMOF nanosheets. Further, AMOF nanosheets showed notable photocatalytic performance for various dye pollutants degradation. The results confirmed 74.5, 85.5, and 90.7% of MO, CV, and MB dye pollutants removal after 120 min of irradiation with the rate constants (k) of 0.0123, 0.0153, and 0.0158 min−1, respectively. The effect of superoxide radicals (O2−) and photogenerated holes (h+) on the organic dye pollutants removal was investigated using radical scavenger trapping studies. Moreover, the stability study also confirmed the recyclability of the photocatalyst. Therefore, the findings of this research present a realizable method to grow AMOF photocatalyst for successful degradation of various dye pollutants.

“…Ternary metal oxides with the perovskite structures of ABO 3 and A 2 BO 4 are gaining more attention than binary metal oxides, given that they allow better tunability of the bandgap, work function, and conductivity by adjusting the relative ratio of cations. [190][191][192][193][194][195] BaSnO 3 (BSO) is a wide bandgap (i.e., 3.2 eV) n-type transparent semiconductor with a perovskite structure similar to the photoactive layer. High-temperature processed BSO led to reduced charge recombination and charge transfer resistance at the BSO/perovskite interface, delivering PCEs close to 12%.…”

“…The high-resolution spectra analysis of Ba and Sr is presented in Figure d,e, respectively. The peaks at 778.68 and 793.95 eV corresponded to Ba atoms in the perovskite structure of the films, whereas the divided peaks centered at 794.88 and 779.55 eV corresponded to the Ba atoms in the nonperovskite structure of the coatings. , The ratios of the perovskite structure versus nonperovskite structure for each peak are shown in Table . Similarly with Ba, the 3d 5/2 and 3d 3/2 peaks of Sr can be divided into peaks (132.32 and 134.20 eV) and (132.87 and 134.70 eV) attributed to perovskite and nonperovskite structure, respectively. , Furthermore, the contents of the perovskite structure in the coatings showed the following trend: BST-3 > BST-2 > BST > BTO (Table ), which is in agreement with the XRD result.…”

One of the major challenges for Ti-based implants is insufficient osteointegration, which might result in the loosening of the implant. In this study, we fabricated strontium (Sr)-containing barium titanate (BST) on the surface of Ti to improve the bioactivity for osteointegration enhancement. The introduction of Sr significantly reduced the crystallization time and improved crystallinity, which was proved by X-ray diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy. Compared with Ti, the BST film showed greater wettability surface and lower elastic modulus and hardness. Furthermore, in synergy with the release of Sr ions, the BST film improved early adhesion and followed osteogenic differentiation of rat bone mesenchymal stem cells. Furthermore, the bone implantation experiment suggested that the BST film could significantly improve the in vivo osteogenesis and osteointegration capabilities of Ti implants. In summary, this study revealed that BST-modified Ti has potential application in bone repair.
