Herein, we developed an efficient method to synthesize 3D hierarchical porous BiOI–BiS S-scheme heterojunction with oxygen vacancies (Ov-BBS) induced by sulfur doping and systematically investigated regulation of oxygen vacancies by sulfur doping and their effects on photocatalytic performance. Results showed that sulfur species promoted the formation of S-scheme heterojunction but depleted oxygen vacancies in Ov-BiOI. The optimal sulfur doped catalyst (Ov-BBS-0.1) exhibited excellent UV–vis light photocatalytic activity towards four representative pollutants, affording removal rate of 97.1 % for MB, 97.6 % for RhB, 99.4 % for Cr(VI), and 92.0 % for TC, respectively, which were higher than those of pristine BiS, BiOI, Ov-BiOI, Ov-BiOI/BiS mixture, Ov-BBS-0.05, and Ov-BBS-0.2. Deep characterizations and theoretical studies certified that the four-pronged enhancement strategy of 3D hierarchical porous structure, oxygen vacancies, sulfur doping and the constructed S-scheme heterojunction, not only enriched accessible active sites, but also promoted electronic polarization and modulated electronic structure, resulting in rapid separation and migration of photogenerated carriers. Moreover, considering the excellent stability and cyclic photocatalytic performance, the film prepared by pumping Ov-BBS dispersion was also satisfactory in the practical application of circulating sewage treatment. Overall, the present work provides a novel approach for the design of more photocatalysts with high efficiency.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":"13 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The skin's close interaction with the outside makes it particularly vulnerable to many injuries. Bacterial infections cause wound healing to take longer, raise the risk of chronic harm, and serve as a breeding ground for drug-resistant bacteria. As a result, it is critical to eliminate bacterial species from the wound region rapidly and efficiently. Metal-organic frameworks (MOFs), are critically adjustable hybrid materials that integrate organic ligands with coordination metals to generate a range of topologically isomorphic structures. MOFs' creation and shape are investigated by the metal source and ligand utilized in the reaction process, and the structural benefits of this near-infinite combination of structures allow boundless potential for their surface functionalization. MOF has a large effective surface area, tunable structure, adaptability, excellent biodegradability, high drug load, adjustable release of drugs, robust targeting, etc. It can be loaded with therapeutic materials and has programmability. It is more conducive to treating complex wounds while realizing the synergistic effects of antibacterial, anti-inflammatory, and pro-angiogenesis, effectively improving treatment safety. This review summarizes the most recent research advances on various MOFs for antimicrobial therapy, using diverse types of metal-ion-based MOFs as an entry point. Finally, it covers several important challenges in the antimicrobial treatment of metal-ion-based MOFs.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":"214 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of chemical functionalities of the COFs on the effective self-diffusivity of the probe molecules within the pore space and the adsorbate/adsorbent interactions were investigated. In particular, diffusion and interaction of water, methanol, -octane, and 1,3,5-triisopropylbenzene (1,3,5-TIPB) within COF–SIOC and COF-DHTA were assessed. The two types of COFs used in this study possessed a dual pore Kagome structure consisting of larger hexagonal and smaller triangular pores. The PFG NMR results show the presence of two distinct diffusion coefficients for small probe molecules, such as water, methanol, and -octane. This behaviour is attributed to their relatively smaller kinetic diameters, allowing them to access both smaller and larger pores in the COFs. In contrast, the PFG diffusion plot for 1,3,5-TIPB showed a single component linear behaviour, which is attributed to diffusion through the larger hexagonal pores only, as a result of a much larger kinetic diameter of 1,3,5-TIPB compared to the other probe molecules, which prevents access to the smaller triangular pores. The presence of functional groups affects surface interactions between the probe molecules and the surface of the COFs. The NMR / relaxation measurements reveal a higher strength of surface interaction for water molecules in COF-DHTA compared to COF–SIOC, which is attributed to the presence of hydrophilic –OH groups in COF-DHTA. Conversely, a higher strength of surface interactions was achieved for -octane in COF–SIOC, due to the hydrophobic nature of this material. This work reports new insights into transport and dynamics of molecules confined in COFs, which can help design and optimisation of such pore structures in applications such as separation and catalysis.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":"12 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, poor conductivity, low stability, and aggregation propensity have been considered as its major drawbacks. In this study, we have successfully constructed the amorphous/crystalline NiCo-LDH@CoP@NiCo–P heterogeneous interface composites by introducing two phosphate shells to improve the electrochemical properties. The combination of NiCo–P's high rate performance with the high capacitive performance provided by the CoP coating addresses the issue of insufficient conductivity of the original NiCo-LDH, resulting in composite electrodes with excellent electrochemical performance. At the current density of 1 A g, the specific capacitance is 1652.8 F g, and the rate performance is 70.8 % when the current increases to 20 times. The capacitance retention is 87.5 % after 5000 cycles at 30 A g. The asymmetric supercapacitor prepared with AC as the anode electrode shows a high specific capacitance of 118 F g in the water-based electrolyte system, with a capacitance retention of 60.1 % after 10,000 cycles at 10 A g. Furthermore, at a power density of 800 W kg, it exhibites a maximum energy density of 42 Wh kg.

Besides, PCL@Au-PDA provides exceptional extracellular matrix (ECM) for cell adhesion, nerve growth, proliferation, and differentiation of PC-12 and high affinity to S-42 cells. The gene expression analysis (qRT-PCR) showed a significantly increased expression level of the Actin beta, TREK-1, and MAP2 which further implied enhanced cell migration, proliferation, maturation, and differentiation. There was more than a 2.2-fold increase in the neurite length with PCL@Au-PDA as compared to pure PCL. Also, PCL@Au-PDA showed excellent photothermal efficiency and was found to ablate 95.23 % MCF-7 cells in 5.0 min at 0.5 W/cm of NIR laser power. The 15 nm PDA surface coating on AuNPs amplifies the photothermal effect of PCL@Au-PDA and accelerates the conversion of light energy to heat energy which stimulates the destruction of human breast cancer cells. FACS analysis showed the apoptotic percentages for MCF-7 cells at 69.67 % with PCL@Au-PDA whereas for pure PCL only 7.93 % were recorded which suggested that the superior plasmonic photothermal efficacy of PCL@Au-PDA even at low power density.
