New battery systems based on solid electrolytes are the main candidate materials for future power batteries owing to their high safety and energy density. Thus far, researchers have conducted extensive studies on the ionic/electronic transfer mechanisms of solid electrolytes and electrode materials, as well as the cooperative effects and interface issues between them. Although much progress has been made, the practical application of solid-state batteries is still severely limited by the high interface impedance between the solid electrolyte and the anode. This impedance stems from incompatible physical and chemical properties and dynamic interface evolution. This paper focuses on the latest progress in the interface engineering strategies of solid electrolytes and anodes and systematically analyzes the cooperative coupling effect between charge transfer dynamics and mechanical stability at the interface.

This method offers unprecedented control over the structural properties of BNPs and in general nanoalloys, with the polymer matrix playing a critical role in regulating nanoparticle formation, spatial arrangement, and size uniformity. The PDGDA matrix enhances nanoparticle stability through steric stabilization and controlled diffusion, effectively maintaining small nanoparticle sizes (∼2.4–2.8 nm) and low dispersity (<em>σ</em><small><sub>D</sub></small>/<em>D</em> = 0.16) during extended high-temperature annealing. Confinement of nanoparticles (NPs) was significantly accelerated by successive thermal annealing to 320 °C, which increased polymer chain mobility and reduced viscosity, enabling rapid diffusion while preserving the structural integrity of the polymer matrix.

However, their practical applications are limited by poor environmental stability. To address this challenge, we employ a zeolitic imidazolate framework (ZIF), specifically ZIF-8, as a stabilizing matrix for its exceptional thermal and chemical stability, high surface area, and versatile synthesis routes. The CPB/ZIF-8 nanocomposite was synthesized by integrating hot-injection-produced CPB NCs with ZIF-8 using an optimized mixing approach, ensuring a uniform NCs distribution. Electron microscopy (EM) analysis confirmed the well-controlled and uniform distribution of the NCs on the surface of the ZIF-8. Moreover, the Fourier-transform infrared spectroscopy (FTIR) revealed ligand exchange, where the imidazole linkers of the ZIF-8 structure replace the NCs ligands. The process advances almost epitaxial attachment of the latter, thus promoting effective charge interactions in the integration process. Indeed, we observe that upon formation of the composite, there is a 92% quenching in the photoluminescence (PL) of the NCs. This finding further indicates efficient charge separation and reduced electron–hole recombination. To gain deeper insight into the charge transfer mechanisms, we conducted electron paramagnetic resonance (EPR) measurements to compare the radical generation capabilities of CPB and ZIF with those of the CPB/ZIF composite. The composite exhibited superior radical generation capabilities, particularly hydroxyl radicals (˙OH), indicating enhanced charge transfer. These findings suggest that the composite is a highly promising candidate for photocatalysis. Building on these findings, we explored the photocatalytic abilities of the composite through dye degradation experiments, using methyl orange (MO) and bromocresol green (BCG) as model dyes. The CPB/ZIF nanocomposite demonstrated significantly enhanced photocatalytic performance compared to pristine ZIF and CPB NCs. Specifically, its degradation rates were 1.48× and 1.75× higher for MO and BCG, respectively, than those of CPB NCs. This improvement highlights the effective interaction between CPB NCs and ZIF, establishing the CPB/ZIF nanocomposite as a promising material for photocatalysis and optoelectronic applications.</p>","PeriodicalId":18806,"journal":{"name":"Nanoscale Advances","volume":" 12","pages":" 3764-3777"},"PeriodicalIF":4.6,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12076080/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144078661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
