Here, a MoSSe/GeP heterostructure is fabricated using an Elvacite pickup transfer strategy, enabling a clean van der Waals junction and contamination-free electrical contacts. Structural and spectroscopic characterizations, including AFM, Raman spectroscopy, and Raman mapping, collectively confirm high crystalline quality, uniform layer thickness, and a chemically sharp interface. Electrical transport measurements further show that GeP exhibits p-type behavior, whereas Janus MoSSe displays n-type conduction, thereby confirming their suitability as complementary semiconductors for p-n junction formation. The pristine p-n junction device exhibits strong rectification (2.2 × 10³ at <i>V</i>_<i>g</i> = − 40 V). After sensitization with lead-free perovskite quantum dots (<i>λ</i>_<i>em</i> ≈ 510 nm), the QD-MoSSe/GeP heterostructure exhibits a pronounced built-in field-driven photocurrent of approximately 0.25 µA at zero bias, confirming efficient interfacial separation. QD integration enhances responsivity, detectivity, and <i>EQE</i> from 1.64 × 10⁴ AW^-1, 3.55 × 10¹³ Jones, and 2.36 × 10⁴% to 4.05 × 10⁴ AW^-1, 7.6 × 10¹³ Jones, and 1.41 × 10⁵%, respectively, at 455 nm, 5.53 mWcm^-2, and <i>V</i>_<i>ds</i> = 1.5 V. Photoexcitation in the quantum-dot layer enables charge transfer into the MoSSe channel, while long-lived trapped charges induce electrostatic gating, leading to pronounced photogating-assisted gain. In addition, under zero-bias operation, the QD-sensitized device achieves an <i>EQE</i> of 8.4 × 10²%, responsivity of 8.75 AW^-1, and detectivity of 0.56 × 10¹⁰ Jones, confirming self-powered functionality. These enhancements originate from spectral resonance, efficient QD-to-MoSSe charge transfer, reduced recombination, and photogating-assisted gain.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"9 5","pages":""},"PeriodicalIF":15.5,"publicationDate":"2026-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-026-01930-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a phytic acid (PA)-enhanced HTC system was developed using willow biomass harvested from HMs-contaminated soils. PA promoted biomass decomposition and carbonization, yielding 37.04%–54.42% hydrochar with high heating values of 23.73–27.75 MJ/kg. Importantly, PA addition significantly promoted HM migration from the solid to the liquid phase, achieving removal efficiencies of 99.61% for Cd and 92.45% for Zn at 0.75 wt% PA, which further increased to 99.95% and 99.65% at 5 wt%, respectively. The hydrochars exhibited excellent HMs adsorption capacities (1.57 ± 0.08–6.40 ± 0.47 mg/g for Cd²⁺; 4.80 ± 0.46–15.30 ± 0.06 mg/g for Cu²⁺), with PAHC-40 achieving the highest maximum adsorption capacities (Q_max) of 22.82 mg/g for Cd²⁺ and 87.78 mg/g for Cu²⁺. These adsorption behaviors fit well with pseudo-second-order kinetic model and the Langmuir isotherm model. The adsorption process is governed by multiple mechanisms, including surface complexation, cation exchange, and cation-π interaction. Application of 3% PAHC improved soil porosity by 16.8%, increased cation exchange capacity to 97.61–102.57 cmol/kg, and promoted transformation of HMs to stable forms (Cd: 0.59%; Zn: 0.29% at week 10). Ecological risk was reduced (PAHC: RI = 224.81) compared with WHC (250.44) and control (301.48).

Accordingly, a design principle that couples oxygen-rich activated carbons (C-X: X = A [acid-oxidized] or P [permanganate-oxidized]) and amino functionalized MIL type metal organic frameworks (NH₂-MIL MOFs) with different metal centers (M-Y: Y = F [Fe], A [Al], or T [Ti]) is implemented to screen composite pairs for synergistic FA conversion under DRT, ambient conditions. The optimal pairing, C-A with M-T, is then formulated as CM-Z, where Z is the C-A/M-T weight ratio (in %). The air purifier (AP) constructed with CM-50 honeycomb filter exhibits superior performance against a wide range of FA concentrations (1–100 ppm). For dry FA (5 ppm), CM-50 demonstrates a clean air delivery rate of 6.92 L min^− 1 with sustained mineralization capability (~ 60% CO₂ yield) over five consecutive cycles at DRT. Mechanistically, the enhanced performance arises from an emergent, interface-enabled reaction pathway rather than a simple synergistic effect of adsorption and catalysis. Density functional theory reveals that the NH₂-MIL-125(Ti) stabilizes and activates FA at Ti–O and –NH₂ sites, while the oxygen rich carbon (C-A) facilitates proton transfer across the interface. This cooperative activation is corroborated by the detection of intermediates (e.g., CH₂O₂, HCOO⁻, CO₃²⁻, H₂O, and CO₂) and by the evolution of surface elemental states in CM-50 during the filtration at DRT. This interface-enabled catalytic adsorption mechanism supports sustained FA conversion and partial mineralization without external energy input. The results position CM-based catalytic adsorbents as a viable, energy-independent platform for indoor air quality management.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"9 5","pages":""},"PeriodicalIF":15.5,"publicationDate":"2026-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-026-01881-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
