Developing advanced nanocomposite phase change materials (PCMs) integrating zero-energy thermal management, microwave absorption, photothermal therapy and electrical signal detection can promote the leapfrog development of flexible wearable electronic devices. For this goal, we propose a multidimensional collaborative strategy combining two-dimensional (2D) MXene nanosheets with metal-organic framework-derived one-dimensional (1D) carbon nanotubes (CNTs) zero-dimensional (0D) metal nanoparticles. After encapsulating paraffin wax (PW) in three-dimensional (3D) networked MXene/CoNi-C, resulting composite PCMs exhibit excellent energy storage capacity long-term thermally reliable stability. Benefiting from synergistically enhanced effects CNTs, Co/Ni nanoparticles MXene, PW@MXene/CoNi-C capture photons efficiently transfer phonons quickly, yielding an ultrahigh conversion efficiency 97.5%. Additionally, high absorption minimum reflection loss −49.3 dB at 8.03 GHz heat-related application scenarios. More attractively, corresponding film simultaneously achieve management electromagnetic shielding devices, as well for individuals. This functional integration design provides important reference developing multifunctional

Machine‐learning‐assisted intelligent synthesis of UiO‐66(Ce): Balancing the trade‐off between structural defects and thermal stability for efficient hydrogenation of Dicyclopentadiene

Materials Genome Engineering Advances, Journal Year: 2024, Volume and Issue: unknown

Abstract Metal‐organic frameworks (MOFs), renowned for structural diversity and design flexibility, exhibit potential in catalysis. However, the pursuit of higher catalytic activity through defects often compromises stability, requiring a delicate balance. Traditional trial‐and‐error method optimizing synthesis parameters within complex chemical space is inefficient. Herein, taking typical MOF UiO‐66(Ce) as an illustrative example, closed loop workflow built, which integrates machine learning (ML)‐assissted prediction, multi‐objective optimization (MOO) experimental preparation to synergistically optimize defect content thermal stability efficient hydrogenation dicyclopentadiene (DCPD). An automatic data extraction program ensures accuracy, establishing high‐quality database. ML employed explore intricate synthesis‐structure‐property correlations, enabling precise delineation pure‐phase subspace accurate predictions properties. After two iterations, MOO model identifies optimal protocols high (>40%) (>300°C). The optimized exhibits superior performance DCPD, validating precision reliability our methodology. This ML‐assisted approach offers valuable paradigm solving trade‐off riddle materials field.

Ligand-Defect-Rich Nh2-Mil-125 Photocatalyst Via Alkaline Adjustment to Accelerate the Transfer of Photogenerated Charge Carriers for Highly Efficient Photocatalytic Hydrogen Production and No Removal

Published: Jan. 1, 2025

Energy scarcity and atmospheric pollution (NOx) are key challenges in current energy environmental management. Photocatalysis provides a sustainable solution, but it is often limited by the high recombination rate of photogenerated carriers photocatalysts. In this study, series NH2-MIL-125 (NM-125) with different ligand defect contents were constructed adjusting concentration alkaline to achieve photocatalytic hydrogen production NO removal efficiency. Compared original NM-125, defective NM-125 exhibits superior activity, maximum efficiency 3.73mmol• g-1• h-1 highest 61.6%. These all attributed unsaturated metal active sites generated defects which significantly enhances migration charge carriers. This study an innovative approach improve MOFs materials via constructing defects.
