Recent progress has focused on improving their sensing performance, selectivity, and response/recovery times. Our Review offers a thorough summary of the most recent progress in the use of MXene-based nanocomposites for smart gas sensors. The study explores the synthesis of pure MXenes from different MAX phases using selective etching and suitable etchants and delaminating agents. It also discusses the characteristics of MXenes and their applications. Further analysis looks at how the performance of gas sensors is impacted by various parameters including humidity, thickness, surface area, concentration, temperature, functional groups, and substrate. Moreover, this Review discusses the existing difficulties in the subject and suggests potential avenues for future research to tackle these hurdles. This work intends to provide guidance for the fabrication of next-generation smart gas sensors using MXene-based nanocomposites. It summarizes recent developments and potential techniques, with the goal of enabling their applications in environmental monitoring, industrial safety, and healthcare diagnostics.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 17","pages":"8521–8569 8521–8569"},"PeriodicalIF":5.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gas-sensing experiments demonstrated that the modified α-Fe2O3@ZIF-71(NBIM) exhibited enhanced selectivity and sensing response toward NO2. At 220 °C, its response to 10 ppm of NO2 was 17.20, which is 1.9 times that of pristine α-Fe2O3 and 1.4 times that of unmodified α-Fe2O3@ZIF-71. When triethylamine was the interfering gas, the material’s selectivity was 1.5 times that of α-Fe2O3@ZIF-71 and 3.3 times that of α-Fe2O3. With NO as the interfering gas, α-Fe2O3@ZIF-71(NBIM)’s selectivity was 1.2 times that of α-Fe2O3@ZIF-71 and 1.4 times that of α-Fe2O3. Meanwhile, the grand canonical Monte Carlo (GCMC) method was employed to investigate the sieving effects of four types of ZIF-71 with different pendant groups. On the other hand, density functional theory (DFT) was utilized to analyze the adsorption mechanisms of NO2 on α-Fe2O3 and α-Fe2O3@ZIF-71(NBIM) nanomaterials. The DFT analysis results were in good agreement with the experimental results. The findings indicated that α-Fe2O3@ZIF-71(NBIM) enhanced the selectivity and response value of metal oxide gas sensors, providing an approach to improve the selectivity and response value of metal oxide gas sensors.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 17","pages":"8690–8701 8690–8701"},"PeriodicalIF":5.3,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, flexible structures are more prone to deformation than rigid building blocks, in other words, it is very challenging to construct COFs with flexible building blocks. Three 2D flexible COFs with 3 + 3 structures are synthesized in this study using a solvothermal method with rigid/flexible building blocks. In addition, the effect of planarity variation of the building blocks on the structure and properties of the COFs is investigated. Subsequently, using high-temperature carbonization, three COFs are used as precursors to prepare nitrogen–oxygen codoped porous carbon materials. The nitrogen–oxygen codoping system and the well-developed porous structure substantially improve the adsorption and electrochemical properties of the materials. In particular, the large number of active sites in the porous system not only enhances the infiltration ability but also improves the diffusion and transport of electrolyte ions and charges within the electrode sheet. The specific capacitance of TAPB-TFPT-COF-700 is 183.9 F g–1 at a current density of 1 A g–1, demonstrating excellent specific capacitance and rate performance. In addition, the three porous carbon materials show excellent cycling stability after 2000 charge/discharge cycles.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 17","pages":"8612–8621 8612–8621"},"PeriodicalIF":5.3,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, only a limited number of photocages have been reported that combine the advantages of excited-state proton transfer (ESPT) and a high two-photon absorption cross-section, enabling the direct photorelease of alcohols without relying on carbonate or carbamate linkages. Henceforth, we strategically modified a “push–pull” based 6-hydroxy-substituted 1,8-naphthalimide (NID) chromophore as an ESPT-induced two-photon responsive photocage NID (5a–d, 6) for the direct release of alcohols. Our developed photocages exhibited a large Stokes shift due to the ESPT process and also demonstrated a change in fluorescence from yellow-orange to blue upon exposure to light, enabling their suitability for image-guided delivery of bioactive molecules. Inspired by these interesting properties, we formulated our photocage as nanoparticles (nano-NID-ES) with enhanced cell penetration ability to release the bioactive molecule estrone (ES). An in vitro study demonstrated that our photoresponsive nanocarrier (nano-NID-ES) exhibited better cellular internalization and real-time monitoring ability in the MCF-7 breast cancer cell line. MTT assay further revealed that nano-NID-ES exhibited an enhanced cytotoxic effect only after exposure to light.

Alloying is a viable strategy to mitigate the suboptimal hydrogen evolution reaction (HER) electrochemical performance associated with the excessively strong Pd–H bonding interaction. This study focuses on synthesizing PdRux alloy nanoparticles on carbon cloth using a combination of atomic layer deposition (ALD) and annealing. By adjusting the number of Ru cycles from 100 to 500 on 200-cycle Pd on carbon cloth, a series of PdRu bimetallic nanoparticle samples were obtained by ALD. The subsequent annealing process was conducted at 600 °C in an argon atmosphere to facilitate the formation of PdRux alloy phases. The density functional theory (DFT) calculation results indicate that some surface configurations of the alloyed PdRux electrocatalysts are better than those of the single metal Ru or Pd, conducive to HER performance. Among them, the annealed 200-cycle Pd-400-cycle Ru alloy electrocatalyst exhibits the best electrocatalytic performance, with an overpotential of 35.6 mV at 10 mA cm–2. Simultaneously, these PdRux alloy nanoparticles show excellent long-term stability with a 40 h chronopotentiometry test at 10 mA cm–2 in acidic media. The enhanced catalytic performance is attributed to the nanoscale size effect of the PdRux alloy nanoparticles and the optimized electronic interaction between alloy components. These synergistic effects lead to a significant reduction in hydrogen binding energy (HBE), thereby substantially improving the HER activity. This work provides enormous potential for the development of highly efficient alloy electrocatalysts by the ALD method.","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 17","pages":"8807–8815 8807–8815"},"PeriodicalIF":5.3,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
