Bimetallic alloy nanoparticles have garnered substantial attention for diverse catalytic applications owing to their abundant active sites and tunable electronic structures, whereas the synthesis of ultrafine with atomic-level homogeneity bulk-state immiscible couples remains a formidable challenge. Herein, we present RuxCo1–x solid-solution (ca. 2 nm) across entire composition range, highly efficient, durable, selective CO2 hydrogenation CH4 under mild conditions. Notably, Ru0.88Co0.12/TiO2 Ru0.74Co0.26/TiO2 catalysts, 12 26 atom % Ru being substituted by Co, exhibit enhanced activity compared monometallic Ru/TiO2 counterparts both in dark light irradiation. The comprehensive experimental investigations density functional theory calculations unveil that state is subtly modulated intimate interaction between Co nanoparticles, this effect results decline conversion energy barrier, thus ultimately culminating an elevated performance relative catalysts. In photopromoted thermocatalytic process, photoinduced charge carriers localized photothermal play pivotal role facilitating chemical reaction which accounts further boosted methanation performance.

Metal–organic frameworks (MOFs) are widely applied in various fields, including energy storage, drug delivery, wastewater treatment, and much more. However, their use hydrogels is limited due to low dispersion which causes agglomeration the hydrogel network many properties of sacrifices. Similarly, conductive have emerged as a promising material for skin-like sensors excellent biocompatibility mechanical flexibility. like MOFs, also face challenges such stretchability, toughness, susceptibility fatigue, resulting sensing range large response time-reduced durability sensors. In this study, highly stretchable, tough, antifatigue composite poly(dodecyl methacrylate-acrylamide-2-(acryloyloxy)ethyl trimethylammonium chloride) bimetallic metal–organic framework [p(DA-AM-AETAC)BM-MOF] was developed by integrating BM-MOFs into it. To achieve uniform within network, positively charged surfactant, ethyl hexadecyl dimethylammonium bromide, used. It facilitates formation hydrophobic interactions between matrix surface BM-MOFs. Furthermore, it can interact with surfactant polymer chains through physical interactions, significantly enhancing hydrogel. The BM-MOF-based exhibited impressive stretchability (1588%) toughness (537 kJ m–3), along exceptional properties. Moreover, demonstrated high conductivity 1.3 S/m tensile strain sensitivity ranging from 0.5 700% gauge factor 14.8 at response–recovery 195–145 ms. p(DA-AM-AETAC)BM-MOF displayed sensitive, reliable, repetitive detection wide human activities, wrist elbow rotation, finger bending, swallowing motion, speaking, well handwriting drawing. monitor pressure mimic skin.

Nb₂CT_x MXene/Delignified Wood–Supported Phase-Change Composites with Desirable Photothermal Conversion Efficiency and Enhanced Flame Retardancy for Solar–Thermal Energy Storage

ACS Applied Energy Materials, Journal Year: 2024, Volume and Issue: 7(6), P. 2178 - 2188

Published: March 14, 2024

Although organic phase-change materials (PCMs) have been widely used for thermal energy storage, their high flammability, poor photothermal conversion efficiency, and liquid leakage issues severely restrict practical applications in solar–thermal fields. Herein, novel form-stabilized composite PCMs (CMPCMs) with storage density, excellent flame retardancy, desirable efficiency were prepared by impregnating n-docosane into phytic acid (PA)/melamine (MEL)-modified Nb2CTx MXene/delignified wood (CMDW) under vacuum assistance. The interconnected three-dimensional porous CMDW supported avoided PCM leakage, owing to its strong surface tension capillary forces. Differential scanning calorimetry analysis revealed that the CMPCMs exhibited satisfactory encapsulation ratios (up 91.6%) superior densities (190.2–219.5 J/g). Decorating delignified through MXene nanosheet deposition considerably improved 89.5%). Furthermore, increasing content of PA MEL composites, total heat release peak rate decreased remarkably due synergistic nitrogen–phosphorus flame-retardant mechanism, suggesting improvement properties CMPCMs. Overall, shape-stabilized demonstrate tremendous potential management applications.

RuOx(1 wt %; 2.2 ± 0.9 nm)@UiO-66(Zr/Ti)-NO2 was found to be reusable photocatalyst, selective methanation (5.03 mmol g-1 after 22 h;, apparent quantum yield 350, 400, 600 nm 1.67, 0.25, 0.01%, respectively), show about 3-6 times activity compared with previous investigations. The photocatalysts were characterized by advanced spectroscopic techniques like femto- nanosecond transient absorption, spin electron resonance, photoluminescence spectroscopies together (photo)electrochemical measurements. photocatalytic mechanism assessed operando FTIR spectroscopy. results indicate that most active photocatalyst operates dual photochemical photothermal mechanism. This investigation shows potential MOFs solar-driven recycling.
