The 1.4 % CuO/TiO₂ system achieves an 84.88 % NOR degradation efficiency in 60 min and maintains over 78.42 % efficiency after five cycles when exposed to visible light, which is higher than that of CuO and TiO₂, respectively.

Practical SCs demand inexpensive and stable electrode materials. Owing to their appealing physical and chemical properties, transition metal molybdates are considered as a prospective electrode material. Herein, metal molybdate (XMoO₄, X = Co, Mn, Ni, Zn) have been synthesized employing a facile sol–gel auto combustion process. X-ray powder diffractometer was employed to validate the synthesis of the nanostructures. The prepared samples surface morphological characteristics and elemental composition were examined employing an energy dispersive X-ray spectroscope combined with a scanning electron microscope. The morphologies were further investigated by transmission electron microscope. X-ray photoelectron spectroscope was employed to examine the synthesized samples for element oxidation states. The electrochemical behaviour of different samples was examined in two-electrode SC system employing electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and galvanostatic charge/discharge (GCD) techniques. EIS along with CV and GCD confirm the SC electrode behaviour of the synthesized materials. The impact of the inherent characteristics of electrodes on specific capacitance was examined by the comparative experimental study. Co based molybdate showed excellent specific capacitance (318.22F g⁻¹), specific power (0.89 kW kg⁻¹) and specific energy (11.04 Wh kg⁻¹) at a current density of 0.5 A g⁻¹, while the best cyclic stability (capacitance retention of about 95 % after 10,000 cycles) was displayed by Mn based molybdate. The high electrical conductivity and superior quality of the sample, that facilitates rapid ion movement and aqueous electrolyte medium interaction, may be accounted for the remarkable electrochemical performances. Overall, the observed results emphasize the significance of molybdate nanostructures as a potential electrode material for next-generation energy storage applications.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"178 ","pages":"Article 114514"},"PeriodicalIF":4.4,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143829750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these materials exhibit restricted capabilities in terms of tribological and antibacterial performance for dental purposes. A newly modified composite YSZ–xBAG (x = 0–25 wt%) has been prepared. The present investigation examines the effect of bioactive glass (BAG) addition on the tribological and antibacterial response of the YSZ-BAG composite. The tribological test is performed on a bio-tribometer under simulated body fluid (SBF) at 37°C. The surface morphology of worn surfaces is studied by HR-SEM/EDS. Tribological results indicate that the wear rate and coefficient of friction (COF) first decrease up to 10 wt% of BAG addition and then increase up to 25 wt% of BAG content. YSZ with 10 wt% of BAG displays superior antifriction and wear resistance properties, with an average COF of 0.17 and a wear rate of 0.63 × 10^–6 mm³ per mm of sliding distance. The optical profilometer is used for surface topography analysis of worn surfaces. Line and surface roughness are almost enhanced by enhancing the BAG content into YSZ ceramic. The surface morphology of worn surfaces of composite samples shows that each sample undergoes pull-out during the rubbing process. Antibacterial tests on composite samples are conducted with Gram-positive (S. aureus; MTCC 435) and Gram-negative (E. coli; MTCC 443) bacteria. The antibacterial result demonstrates that the presence of BAG considerably reduces the bacterial cells’ viability on the composite samples. The live/dead ratio for E. coli of all samples (0, 5, 10, 15, and 25 % of BG) are 13.83, 4.93, 3.31, 2.28, and 1.80, respectively, and for S. aureus are 15.33, 5.53, 3.63, 2.61, and 2.12, respectively.

Although noble metal catalysts can realize the low-temperature and efficient degradation of CVOCs, their high cost and easy to accumulate carbon and sintering limit the practical application.

Based on this, four cerium-chromium doped catalysts, Ce_1-<em>_x</em>Cr<em>_x</em>O₂-M, where M stands for rod (R), cube (C), particle (P), and spindle (S), were prepared by a two-step hydrothermal method in the present study to systematically investigate the mechanism of chromium doping on the structural remodeling and catalytic performance of CeO₂. It is shown that chromium doping induces the formation of Ce-O-Cr solid solution, which increases the defect site density and promotes the generation of oxygen vacancies by regulating the oxygen atom arrangement, and significantly enhances the trapping and activation of gas-phase oxygen. Among them, Ce_1-<em>_x</em>Cr<em>_x</em>O₂-S showed the best DCM degradation performance (T₅₀ = 179 °C, T₉₀ = 304 °C), which was attributed to the high specific surface area of the unique morphology, the high density of acidic sites on the surface to promote the dissociation of the C-Cl bond, and the optimized redox properties to accelerate the generation and conversion of reactive oxygen species, which synergistically achieved the high efficiency and depth of the DCM. The three synergies achieved the efficient deep mineralization of DCM. The process optimization shows that 500 ℃ roasting can effectively maintain the active structure.
