ZnO<sub>1−<i>x</i></sub> photocatalysts containing oxygen defects were prepared by the “oxygen-atom capture” method in different lithium-naphthalene solution. The effect of concentration of lithium-naphthalene solution on the oxygen vacancies and photocatalytic performance of ZnO was researched comprehensively. The results indicate that ZnO photocatalysts treated in lithium-naphthalene solution show disordered structure on the material due to the presence of oxygen vacancies. Compared with W-ZnO (white ZnO), ZnO<sub>1−<i>x</i></sub> exhibits higher visible light absorption and enhanced photocatalytic properties. Moreover, more oxygen vacancies are introduced into ZnO-0.8, which reduce its bandgap to 3.04 eV and improve the separation efficiency and transfer speed of photo-generated carriers. Therefore, the efficiency of NO removal by ZnO-0.8 is enhanced to 54.3% under ultraviolet light irradiation, and its degradation efficiency of NO is ~ 12 times greater than that of W-ZnO. Oxygen vacancies acted as capturer of electrons, inhibiting the recombination of photogenerated electrons and holes. Thus, increasing the appropriate concentration of oxygen vacancies on the surface of the material can enhance its photocatalytic activity.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"26 10","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142411319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we prepare MoS<sub>2</sub> quantum dots (QDs) by the LPE method using deoxyadenosine monophosphate (dAMP) as an exfoliation agent that provides a good biocompatibility of the QDs too. As a result, a visible-range photoluminescence from MoS<sub>2</sub> QDs surrounded by nucleotides is observed for the first time. Different structures of MoS<sub>2</sub> QDs with dAMP are analyzed employing the DFT calculations. It is shown that dAMP can form coordination bonds with the Mo atoms located at the QD edges or at the defect sites where direct contacts with these atoms can occur. The covalent bonds facilitate strong adsorption of dAMP on a MoS<sub>2</sub> QD. The structural flexibility of the nucleotide adsorbed on the MoS<sub>2</sub> QD enables a combination of noncovalent stacking interaction of the nucleobase and a coordination bond of the phosphate group with the Mo atoms located at the edges to occur.

In this study, zinc oxide nanoparticles (ZnO-NPs) were synthesized using ZnSO4.7H2O as a precursor. The synthesized ZnO-NPs exhibited a particle size of 63.60 nm, stability characterized by a zeta potential, and a semispherical agglomerated shape under scanning electron microscopy (SEM). The purity of the nanomaterials was confirmed through energy-dispersive X-ray spectroscopy (EDAX). SEM-EDAX analysis of groundnut seeds primed with ZnO-NPs showed improved zinc adsorption and distribution compared to bulk ZnSO4, with no physical damage, indicating good biocompatibility. The small size and high surface area of the nanoparticles enhanced zinc uptake, as confirmed by higher zinc levels in ZnO-NP-treated seeds. ZnO-NP priming resulted in greater physio-biochemical responses, enhancing germination and the seedling vigor index at 10 days post-sowing. Biochemical analysis revealed elevated levels of chlorophyll, soluble protein, total soluble sugar, and free amino acid in the leaves of ZnO-NP-treated plants. Furthermore, ZnO-NP-treated groundnut seedlings exhibited significantly greater DPPH radical scavenging activity than control plants, indicating enhanced antioxidant potential. This study further explored the elevations in the levels of antioxidant enzymes (superoxide dismutase-SOD, catalase-CAT, ascorbate peroxidase-APX, guaiacol peroxidase-GPX and polyphenol oxidase-PPO) primed with ZnO-NPs to augment the hydration of seeds, increase antioxidant enzyme activity to neutralize reactive oxygen species, preserve cellular integrity, and promote overall plant health.

Furthermore, we investigated their performance in photodegrading 1,5-dihydroxynaphthalene (1,5-DHN) into 5-hydroxy-1,4-naphthalenedione (Juglone). Integrating metalloporphyrin-based ligands into bimetallic MOFs represents a pioneering advancement in this field. Photocatalytic reactions were conducted using various stoichiometric ratios of Co and Zn as metal nodes, along with meso-tetra(4-carboxyphenyl)porphyrin (TCPP-H<sub>2</sub>) and Mn(III) meso-tetra(4-carboxyphenyl)porphyrin chloride (Mn-TCPP) as linkers. Results revealed that Co as a node led to the formation of nanorod metal–organic frameworks (MOF) structures, while Zn enhanced photocatalytic activity. Significantly, a photodegradation yield of 72% was achieved with a 1:3 molar ratio of Co to Zn in Zn<sub>75%</sub>/Co<sub>25</sub> (TCPP-Mn), demonstrating a synergistic interplay between Co to Zn nodes and Mn-porphyrin linkers. Characterization was performed using structural and microscopic methods. Additionally, various parameters were optimized to elucidate the photocatalytic mechanism, revealing the promising potential of MM-MOFs for efficient photodegradation of 1,5-DHN and beyond. It is noteworthy that the integration of metalloporphyrin-based structures into MM-MOFs for photodegradation processes is relatively uncommon, underscoring the novelty and potential significance of incorporating porphyrin-based ligands in mixed metal MOFs for photodegradation applications.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"26 10","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142410428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
