Abstract
A broad range of chemical transformations driven by catalytic processes necessitates the electron transfer between catalyst and substrate. The redox cycle limitation arising from the inequivalent electron donation and acceptance of the involved catalysts, however, generally leads to their deactivation, causing substantial economic losses and environmental risks. Here, a "non-redox catalysis" strategy is provided, wherein the catalytic units are constructed by atomic Fe and B as dual active sites to create tensile force and electric field, which allows directional self-decomposition of peroxymonosulfate (PMS) molecules through internal electron transfer to form singlet oxygen, bypassing the need of electron transfer between catalyst and PMS. The proposed catalytic approach with non-redox cycling of catalyst contributes to excellent stability of the active centers while the generated reactive oxygen species find high efficiency in long-term catalytic pollutant degradation and selective organic oxidation synthesis in aqueous phase. This work offers a new avenue for directional substrate conversion, which holds promise to advance the design of alternative catalytic pathways for sustainable energy conversion and valuable chemical production.

Effect of B 2O 3 on the Structure, Properties and Antibacterial Abilities of Sol-Gel-Derived TiO 2/TeO 2/B 2O 3 Powders. MATERIALS (BASEL, SWITZERLAND) 2023; 16:6400. [PMID: 37834537 PMCID: PMC10573519 DOI: 10.3390/ma16196400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 09/18/2023] [Accepted: 09/23/2023] [Indexed: 10/15/2023]
Abstract
This paper studies the influence of B2O3 on the structure, properties and antibacterial abilities of sol-gel-derived TiO2/TeO2/B2O3 powders. Titanium(IV) butoxide, telluric(VI) acid and boric acid were used as precursors. Differences were observed in the degree of decomposition of Ti butoxide in the presence of H3BO3 and H6TeO6 acids. The phase transformations of the obtained gels in the temperature range of 200-700 °C were investigated by XRD. Composite materials containing an amorphous phase and different crystalline phases (metallic Te, α-TeO2, anatase, rutile and TiTe3O8) were prepared. Heating at 400 °C indicated a crystalline-to-amorphous-phase ratio of approximately 3:1. The scanning electron microscopy (SEM) analysis showed the preparation of plate-like TiO2 nanoparticles. The IR results showed that the short-range order of the amorphous phases that are part of the composite materials consists of TiO6, BO3, BO4 and TeO4 structural units. Free B2O3 was not detected in the investigated compositions which could be related to the better connectivity between the building units as compared to binary TiO2/B2O3 compositions. The UV-Vis spectra of the investigated gels exhibited a red shift of the cut-off due to the presence of boron and tellurium units. The binary sample achieved the maximum photodegradation efficiency (94%) toward Malachite green dye under UV irradiation, whereas the ternary sample photoactivity was very low. The compositions exhibited promising antibacterial activity against E. coli NBIMCC K12 407.

Abstract
The Sol-gel method is successfully used to prepare high specific surface area TiO2 (HSTiO2). Then, the photodeposition method is used to composite silver particles with HSTiO2. X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller, and UV-vis spectroscopy are used to characterize the Ag/HSTiO2 nanocomposites. It can be concluded that the prepared TiO2 has a large specific surface area, reaching 125.5 m2 g-1. Additionally, the addition of silver particles successfully broadens the photoresponse range from the UV region to the visible light region. In order to evaluate the photocatalytic activity of Ag/HSTiO2, we conducted the methyl orange degradation test. The results showed that the photocatalytic activity of the sample is significantly higher than that of pure TiO2.
