Two-dimensional vanadium carbide (V2C) and titanium (Ti3C2) MXenes were first synthesized by exfoliating V2AlC or Ti3AlC2 then introduced jointly into magnesium hydride (MgH2) to tailor the hydrogen desorption/absorption performances of MgH2. The as-prepared MgH2–V2C–Ti3C2 composites show much better storage than pure MgH2 with addition 10 wt % 2V2C/Ti3C2 initiates desorption at around 180 °C; 5.1 was desorbed within 60 min 225 °C, while 5.8 2 300 °C. Under 6 MPa H2, dehydrided...
Magnesium hydride (MgH2) is a potential material for solid-state hydrogen storage. However, the thermodynamic and kinetic properties are far from practical application in current stage. In this work, two-dimensional vanadium carbide (V2C) MXene with layer thickness of 50−100 nm was fist synthesized by selectively HF-etching Al layers V2AlC MAX phase then introduced into MgH2 to improve sorption performances MgH2. The onset desorption temperature V2C addition significantly reduced 318 °C pure...
In the context of growing challenges associated with pollution prevention and control, developing more efficient technologies precise policy measures to address bottleneck period is imperative. This study utilized daily electricity consumption data from nine prefecture-level cities in Fujian Province January 2019 June 2024 develop a high-quality development index (HQDI) empirically investigate how HQDI affects decoupling economic growth emissions. Results suggest that can significantly...
Hydrogen can serve as a carrier to store renewable energy in large scale. However, hydrogen storage still remains challenge the current stage. It is difficult meet technical requirements applying conventional of compressed gaseous high-pressure tanks or solid-state suitable materials. In present work, and (G-S) hybrid system with low working pressure below 5 MPa for 10 kW experiment platform developed validated. A Ti–Mn type alloy an effective capacity 1.7 wt% was prepared G-S system. The...
Carbon materials have excellent catalytic effects on the hydrogen storage performance of MgH2. Here, carbon-supported Ni3S2 (denoted as Ni3S2@C) was synthesized by a facile chemical route using ion exchange resin and nickel acetate tetrahydrate raw then introduced to improve properties The results indicated addition 10 wt.% Ni3S2@C prepared macroporous can effectively hydrogenation/dehydrogenation kinetic At 100 °C, dehydrogenated MgH2-Ni3S2@C-4 composite could absorb 5.68 H2. Additionally,...
3D self-assembled amorphous carbon-embedded porous niobium pentoxide (C-p-Nb 2 O 5 ) is prepared by the wet chemical method, and C-p-Nb doped MgH show excellent integrated hydrogen storage properties.
Hydrogen is considered one of the most ideal future energy carriers. The safe storage and convenient transportation hydrogen are key factors for utilization energy. In current investigation, two-dimensional vanadium carbide (VC) was prepared by an etching method using V4AlC3 as a precursor then employed to enhance properties MgH2. studied results indicate that VC-doped MgH2 can absorb at room temperature release 170 °C. Moreover, it absorbs 5.0 wt.% H2 within 9.8 min 100 °C desorbs 3.2 300...
We successfully synthesized hybrid MXene-K-CNT composites composed of alkalized two-dimensional (2D) metal carbide and carbon nanotubes (CNTs), which were employed as host materials for lithium–sulfur (Li–S) battery cathodes. The unique three-dimensional (3D) intercalated structure through electrostatic interactions by K+ ions in conjunction with the scaffolding effect provided CNTs effectively inhibited self-stacking MXene nanosheets, resulting an enhanced specific surface area (SSA) ion...
