“…The stretching vibration of aromatic C-H was attributed to the peak at 2800 cm −1 . The bending C-H groups are the reasons for the peak around 760 cm −1 , while those around 700 and 640 cm −1 are related to the Ta-O bond ( Wang et al, 2021 ). According to the results of FTIR spectra and considering various configurations of the linker ( Sargazi et al, 2020 ), the structures of Ta- MOF nanostructures were proposed in Figure 4 .…”

Novel Ta- MOF was synthesized under mild conditions by ultrasound irradiations. The sample was characterized by SEM, FTIR, XRD, XPS, TG and BET technique. The final structures showed high physicho-chemical properties including narrow particle size distribution, homogenous morphology, high thermal stability and remarkable surface area. Ta- MOF synthesized in this study was used as a catalyst in the synthesis of 1,4-dihydropyran derivatives. The results proved that it has a high catalyst capability. Its advantages include high recyclability, less reaction time with higher efficiency and synthesis of new1,4-dihydropyran derivatives. In the following, antimicrobial activity including antifungal and antibacterial activity of Ta- MOF nanoparticles based on Minimum Inhibitory Concentration, Minimum Fungicidal Concentration and Minimum Bactericidal Concentration were evaluated. The synthesized Ta- MOF, in addition to high catalytic properties, showed high antimicrobial activity with MIC value between 16 and −256 μg/ml, and can be introduced as an agent against bacteria and fungi.

“…Furthermore, the consumption of active oxygen leads to the formation of Fe 2+ in metal oxides, and Fe 2+ is reoxidized to Fe 3+ by oxygen in the gaseous phase along with the formation of active oxygen atoms. In contrast, the catalytic oxidation of cyclohexane over the PdAg/Fe 2 O 3 followed both the MVK reaction mechanism and the Langmuir–Hinshelwood reaction mechanism, in which the activation of oxygen by oxygen vacancies to form active oxygen atoms occurs simultaneously with the activation of oxygen by Pd species to form oxidized Pd–O species for cyclohexane oxidation. ,, In the combined PdAg/Fe 2 O 3 reaction mechanism, chemisorbed cyclohexane can be oxidized by both active oxygen atoms and Pd–O to form carbon dioxide, water, reduced Pd species, and oxygen vacancies, and the reduced Pd species and oxygen vacancies (Fe 2+ ) are further oxidized by oxygen molecules, resulting in the recovery of oxidative species for subsequent reaction cycles. Therefore, these results suggest that loading PdAg alloy nanoparticles on Fe 2 O 3 has the advantages of promoting the key reaction step of oxidative cyclohexane dehydrogenation to cyclohexene and benzene and providing an abundance of active sites (oxygen vacancy and Pd sites) for oxygen activation while also increasing the number of moderately acidic sites for cyclohexane adsorption.…”

Cyclohexane, a typical volatile organic compound (VOC), poses high risks to the environment and humans. Herein, synthesized PdAg/Fe2O3 catalysts exhibited exceptional catalytic performance for cyclohexane combustion at lower temperatures (50% mineralization temperature (T 50) of 199 °C, 90% mineralization temperature (T 90) of 315 °C) than Pd/Fe2O3 (T 50 of 262 °C, T 90 of 335 °C) and Fe2O3 (T 50 of 305 °C, T 90 of 360 °C). In addition, PdAg/Fe2O3 displayed enhanced stability by alloying Ag with Pd. The redox and acidity of the PdAg/Fe2O3 were studied by XPS, H2-TPR, and NH3-TPD. In situ diffuse reflectance infrared Fourier transform spectroscopy and proton-transfer-reaction time-of-flight mass spectrometry were applied to identify the intermediates formed on the catalyst surface and in the tail gas during oxidation, respectively. Results suggested that loading PdAg onto Fe2O3 significantly enhanced the adsorption and activation of oxygen and cyclohexane, oxidative dehydrogenation of cyclohexane to benzene, and catalytic cracking of cyclohexane to olefins at low temperatures. This in-depth study will benefit the design and application of efficient catalysts for the effective combustion of VOCs at low temperatures.

The attractiveness of traditional exhibition halls to young people is gradually decreasing. Combining modern digital technology to improve the display effect of the exhibition hall can effectively enhance the effect of cultural publicity. This article introduces the technology of image interaction and mixed reality (MR) to improve the historical and cultural propaganda level of the Shaanxi exhibition hall. The advantages of MR technology in applying digital exhibition halls are theoretically expounded. A theoretical plan for Shaanxi history and culture-related display areas is designed using artificial intelligence combined with MR technology. In addition, the survey respondent’s evaluation of the effect of the new exhibition hall is obtained using a questionnaire survey. The survey results show that 97% of people like the history and culture of Shaanxi but only 13% of the people say they know or know very well about the history and culture of Shaanxi. In addition, 60% of the tourists say they are satisfied with the cultural experience of Shaanxi, and only 27% of the tourists are very satisfied. Also, 96% of tourists are willing to experience Shaanxi’s history and culture through digital exhibition halls, and 93% are willing to participate in cultural experience activities based on MR technology. The survey results prove that tourists are satisfied with the effect of the new exhibition hall. Tourists want to add a distinctive form of cultural experience to the exhibition hall. They are willing to accept digital exhibition halls incorporating MR technology and are very happy to participate in the exhibition method of image interaction. This shows that the use of image interactive display based on MR technology in the layout of the exhibition hall is recognized by people and has strong feasibility. This article has reference significance for the digital upgrade of the exhibition hall and the development of the cultural tourism industry.
