In this study, a bioinspired synthesis route was adopted to synthesize ZrO2-Zr3Er4O12-based mixed nanomaterial using leaf extract of medicinal plant Amaranthus viridis as reducing and stabilizing agent in replacement of the obnoxious chemicals which are a great threat to the sustainable environment. The synthesized material revealed the spherical shaped morphology through scanning electron microscopy, whereas crystal size of 15.7 nm was observed through Xray-diffraction, and band gap value of 2.7 eV was acquired using Tauc plot. Newly synthesized ZrO2-Zr3Er4O12 nanocomposite was then investigated for its role as electrocatalyst in a generation of energy through the hydrogen evolution reaction and oxygen evolution reaction. The ZrO2-Zr3Er4O12-based electrocatalyst showed better potential for hydrogen evolution reaction measurements with the overpotential value of 242 mV. Furthermore, the notable capacitance value of 495.6 F/g was obtained through cyclic voltammetry for energy storage studies. The cyclic stability was also analyzed using linear sweep voltammetry and results showed promising stability for 2000 cycles. Consequently, the green and economical synthesis route as well as promising electrochemical behavior of ZrO2-Zr3Er4O12-based electrode make it feasible choice for large scale application.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 12","pages":"1427-1434"},"PeriodicalIF":1.6,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142860427","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}

The introduction of zinc oxide nanoparticles during fermentation had an impact on output and growth. The biomass percentage was 1.5 times greater and the fatty acid profile was better than in the control samples. The analysis of the induction period (IP) revealed that samples containing zinc oxide nanoparticles had maximum oxidation stability for up to 120 days of storage, along with a considerable reduction in autoxidation. The cetane number and calorific value, however, increased with the addition of ZnO nanoparticles. A new study discovered that the use of ZnO nanoparticles encapsulated in β-CD led to much increased production (63.5 g/L) of microbial oil than the control sample (42.5 g/L). Therefore, it is anticipated that these nanoparticles would find utility in energy-related applications.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 11","pages":"1377-1384"},"PeriodicalIF":1.6,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642487","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}

The frequency fluctuation order is continual at 300 K after heating to 3 ps with very small distraction in the atomic structure conforming the structure stability of the studied structures. Also inclusion of spin-orbit coupling effect on density of states undermines significant change in peaks specially d-states in the materials and caused a degeneracy. Band structure analysis clarified that states crossing the Fermi level have the importance for enhancing the thermoelectric properties of the materials. The topology of the states indicates a gap at the bulk level, which is the unique character of the heavy elements in the materials Co2CrGe, Co2FeGe, and Co2NiGa. Thermoelectric properties are calculated for a temperature of 300 K using semi-classical Boltzmann's theory implemented in BoltzTraP code.

The employment of thermodynamic calculations revealed that the combustion approach is a proper way to synthesize MgAl2O4:Eu3+ material by urea fuel, although this procedure was fulfilled at 500°C, the final temperature will be around 2030°C. The x-ray and FT-IR spectra confirmed the successful formation of spinels, while it was shown that the calcination procedure results in a significant increase of crystallinity. On the other hand, it was interestingly seen that the addition of large amounts of Eu3+dopant (10 wt%) suppresses the crystallinity. The MAUD calculations interestingly revealed that the increase of Eu3+ dopant from 1 to 10 wt% leads to the increase of MgO and Al2O3 impurities. The related microstructural evaluations revealed that the particle size of the synthesized powders is mostly less than 40 nm which shows the superiority of combustion synthesis over other commercial methods. Also, the broadening of XRD peaks confirmed the formation of nano-sized powder. The photoluminescence (PL) characterizations showed that doping of MgAl2O4 with 7 wt% Eu3+ brings the most intensive emission properties at the wavelengths of 592 and 617 nm.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 11","pages":"1368-1376"},"PeriodicalIF":1.6,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264523","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}

Notably, traditional techniques and materials have been employed to clean up pharmaceutical pollutants (PP) from aquatic bodies; however, they have come under controversy because they require hazardous chemicals and cannot fully mineralize stubborn PPs. Interestingly, the photocatalytic degradation approach employing eco-benign biosynthesized nanoparticles (BNP) is an avant-garde practice and has shown to be an eco-sustainable method that can fully mineralize PPs into harmless molecules. Thus, this study critically explores the application of BNPs for the photocatalytic degradation of PPs. The review revealed that the greatest degradation efficacy of BNPs was greater than 80% in most cases, and that the least amount of time required was around 10 min. In addition, the oxygen-containing functional groups found in the biological sources used for the fabrication of BNPs contributed to the supremacy of •OH and O2• radicals in the degradation operation. Also, the photocatalytic degradation kinetic data was well modeled by pseudo-first order, and this indicates that •OH was more involved in the PPs degradation operation than O2•. Moreso, BNPs have excellent reusability potential (>5 rounds) while maintaining inherent structural integrity. Techno-economic analysis revealed that BNPs are cost-effective, costing about $1.5/1,000,000 mL of pharmaceutical wastewater on average.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 11","pages":"1332-1357"},"PeriodicalIF":1.6,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264556","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}
