Herein, we adopted Cynanchum fibers as a carbon source and substrate to construct a ternary hollow core–shell carbon microtubes@TiO₂/ZnIn₂S₄ (denoted as CMT@TiO₂/ZnIn₂S₄) for photothermal-assisted photocatalytic hydrogen evolution (PHE). For the catalyst system, ZnIn₂S₄ is the main visible light absorber, TiO₂ is introduced to form a heterojunction with ZnIn₂S₄ to facilitate the separation of photogenerated carriers, and hollow CMT derived from Cynanchum fibers serves as a conductive scaffold and a photothermal core to elevate the surface temperature of the localized reaction system. Benefiting from the rationally designed multicomponents and microstructures, the photocatalyst proposed enhanced PHE activity of 9.71 mmol·g⁻¹·h⁻¹, which was 30.3, 2.7 and 1.5 times higher than those of binary CMT@TiO₂, pristine ZnIn₂S₄ and TiO₂/ZnIn₂S₄ composite, respectively. The outperformed PHE activity of CMT@TiO₂/ZnIn₂S₄ could be ascribed to the synergy of the formation of intimate heterointerface, the CMT-induced photothermal effect and the hierarchical core–shell architecture.

Research into novel materials for detecting and removing PFASs has increased rapidly, particularly in regard to the emergence of well-characterized single-atom materials (SAMs). Owing to the high selectivity, high atom utilization, and abundant active sites of SAMs, these materials exhibit remarkable efficacy in the detection and removal of PFASs. In this work, recent advances in the synthesis of SAMs for the detection and removal PFASs are reviewed. In-depth discussions of the structure–activity relationship and reaction mechanisms have demonstrated the high efficiency, activity, and selectivity of SAMs for the detection, adsorption, and degradation of PFASs. To optimize the application of SAMs in PFASs remediation, this review comprehensively surveys SAMs applications for PFASs and analyzes potential design strategies based on synthesis methods and corresponding properties. Synthesis strategies such as wet-chemistry, which offer ease of operation and high potential for large-scale production, are recommended for the further exploration of specific SAMs for the detection and removal of PFASs. Finally, this review identifies the challenges and opportunities for development of SAMs for the detection and remediation of PFASs, providing an outlook on strategic goals for a green economy and sustainable development.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 4","pages":"2314 - 2327"},"PeriodicalIF":9.6,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prepared samples were characterised using X-ray diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy. The humidity-sensitive properties of the sensor were investigated, and its monitoring capabilities in applications involving respiration, gestures, skin, and baby diapers were tested. The experimental results indicate that compared with a pure ZIF-67 humidity sensor, the Au@ZIF-67 (0.1Au@Z) flexible humidity sensor exhibits a 158.07% decrease in baseline resistance and a 51.66% increase in sensitivity to 95% relative humidity, and the hysteresis, response time, and recovery time are significantly reduced. Furthermore, the sensor exhibits excellent characteristics such as high resolution, repeatability, and stability.

Cu₆NC possesses a unique metal core configuration and metal–ligand binding motifs. Interestingly, Cu₆NC has superior OER performance to pure phosphine ligand-protected Cu₁₈ nanocluster (Cu₁₈NC in short, same Cu amount) and Cu nanoparticle (CuNP) with larger size, manifested by the lower overpotential at 10 mA·cm⁻², smaller Tafel slope, and reduced charge transfer resistance. Cu₆NC also demonstrated excellent long-term stability for prolonged operation. Density functional theory (DFT) calculations further confirm that the alkynyl ligand plays a critical role in promoting the catalytic performance, and Cu₆NC has a lower energy barrier in the rate-determining step of the OER process.

However, the large electron cloud density between the B-H bonds in LiBH₄ induces high dehydrogenation temperatures and sluggish dehydrogenation kinetics. To solve the above problems, it is proposed to enhance the hydrogen storage properties of LiBH₄ through the synergistic effect of Brønsted and Lewis acid in Hβ zeolite. Composite hydrogen storage systems with different mass ratios were prepared by simple ball-milling. At a LiBH₄-to-Hβ mass ratio of 6:4, the 6LiBH₄-4Hβ system released hydrogen at 190 °C and achieved a hydrogen release capacity of 7.0 wt% H₂ upon heating to 400 °C. More importantly, the hydrogen release capacity of the system reached 6.02 wt% at 350 °C under isothermal conditions after 100 min and 7.2 wt% at 400 °C under isothermal conditions after 80 min, whereas the pristine LiBH₄ only achieved 2.2 wt%. The improvement in hydrogen storage performance of the system was mainly attributed to two factors: (i) Lewis acid sites with acceptable electrons in the Hβ weaken the electron density of B–H bonds in LiBH₄, and (ii) the H⁺ proton from the Brønsted acid sites and H⁻ of LiBH₄ undergo a H⁺  + H⁻ = H₂ reaction. Theoretical calculations revealed that the Lewis and Brønsted acid sites in the Hβ zeolite are conducive to the weakening of B<b>–</b>H bonds and that storage charge transfer occurs near the Lewis acid sites.
