In the past, batteries have been able to meet these demands adequately. However, their low power density (Ps) has inspired alternative energy storage advancements that can foster a transition to net-carbon-zero via renewables. Supercapacitor (SC) innovations, such as the recent emergence of solid-state supercapacitors (SSCs), have gained tremendous attention owing to their mechanical robustness, safety, possible flexibility, long cycle life, portability, prospective high Ps, and suitability for advanced energy technologies. Complimentary to the affordable and lightweight material design requirements is the enormous potential of the graphene family in SSCs owing to facile synthesis advantages, easy scalability and, processing high electrical conductivity, low costs, and mechanical robustness among others. Therefore, the review highlights the recent efforts to advance SSCs with the graphene family in electrodes and electrolytes. The work discusses SC basic concepts and main characterization techniques, and applications of the graphene family in both electrolytes and electrodes of SSCs. Finally, the merits, demerits and prospects of incorporating graphene derivatives to advance SSC performance and sustainability are outlined.

The QSAR model was developed using a dataset of 90 compounds with known iNOS inhibition activity. Molecular descriptors representing the compounds’ structural and physicochemical properties were calculated and employed as input variables. Five descriptors (MATS6p, Chi1_EA(dm), Mor17 s, NsssCH, and SHED_AL) were selected as optimal for developing the classification model. The Random Forest algorithm was chosen as the classifier, implemented using WEKA software. The model underwent rigorous internal and external validation to assess its performance. The resulting QSAR model exhibited outstanding predictive capabilities with an overall accuracy of 88.8 %, a high correlation coefficient, and minimal prediction errors. It effectively forecasts iNOS inhibition activity of the chosen compounds, offering valuable insights for potential Alzheimer's disease treatments. This model significantly contributes to drug discovery, providing a rapid and cost-effective means of screening and prioritizing compounds with iNOS inhibitory potential.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"9 44","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TNTAs have been widely modified with noble metals for increasing their absorption of visible light and limiting their associated rapid electron-hole recombination rate. However, these metals are extremely expensive, which limits their practical applications in the fields of energy and environment. In this study, three noble-metal-free materials of graphitic carbon nitrides, metal–organic framework, and reduced graphene oxide were used for modifying pure TNTAs through a simple drying-deposition method. The modified TNTAs samples were characterized by X-ray diffraction, Fourier transform infrared, field emission scanning electron microscopy and energy-dispersive X-ray spectroscopy analyses for approving successful synthesis of these nanocomposites. Finally, the modified TNTAs nanocomposites were investigated for their ability in converting the CO2 gas to CO under visible light. However, the TNTAs modified with graphitic carbon nitrides displayed the highest CO productions of 27551 µmol m−2 which represents 16% enhancement compared to that of pure TNTAs (23871 µmol m−2). The enhanced CO2 photoreduction performance of modified TNTAs is attributed to promoted light absorption, increased surface area, and improved electrical conductivity.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"9 44","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/slct.202403536","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All catalysts were thoroughly analyzed using various techniques like FT-IR, N2 physisorption, XRD, SEM-EDX, NH3-TPD, ICP spectroscopy, and thermogravimetric analysis (TGA). The results showed that HBEA and HY catalysts, with their larger pore channels and sizes, exhibited excellent activity in breaking the ether bond of PPE-OH. HBEA and HY zeolites exhibited almost full conversion of PPE-OH at 240 °C and 1 h, and HZSM-5 zeolite obtained only 47% conversion of PPE-OH at the same condition. The cleavage of the ether bond of β-O-4 linkage was performed over HBEA and HY zeolites better than HZSM-5 zeolite. Moreover, high-strong acid sites of HBEA zeolite favored breaking PPE at 240 °C and 1 h, and PPE did not convert over HY and HZSM-5 zeolites at the same condition. These findings highlight the crucial role of pore size and channels and the acidity of catalysts for converting large molecules like lignin.

This research addresses the challenge of hexavalent chromium (Cr(VI)) pollution by employing CuCo2O4/TiO2/FTO as visible light-active photocatalyst. The films demonstrated strong absorption in the visible spectrum. The heterostructure comprising CuCo2O4 and TiO2 films was synthesized to enhance the photocatalytic reduction of Cr(VI) through synergetic effects. The CuCo2O4/TiO2/FTO film exhibited superior photoreduction performance, achieving photoreduction efficiencies of ∼62.9% under UV-A and ∼72.3% under visible light, outperforming individual TiO2/FTO and CuCo2O4/FTO films. Reaction rates were 0.00433 min−1 (R2: 0.98893) under UV and 0.00638 min−1 (R2: 0.98787) under visible light, with a half-life of 1.81 h, indicating significant improvement in photocatalytic activity. However, it is necessary to optimize the synthesis parameters to analyze their impact on its physicochemical properties and its behavior as a photocatalyst. Making possible its applicability is due to the appropriate charge transport, visible light absorption, reduced recombination of electron-holes pairs, and improved photocatalytic performance.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"9 44","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/slct.202404596","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretical study shows good agreement with experimental study and NLO analysis suggest that the targeted compounds are good candidates with nonlinear optics.
