Metal hydrides (MHs) have recently been designed for hydrogen sensors, switchable mirrors, rechargeable batteries, and other energy-storage conversion-related applications. The demands of MHs, particular fast absorption/desorption kinetics, brought their sizes to nanoscale. However, the nanostructured MHs generally suffer from surface passivation low aggregation-resisting structural stability upon absorption/desorption. This study reports a novel strategy named microencapsulated...
Ni/Gn catalysts were introduced to obtain Mg-based composites<italic>via</italic>HCS + MM for excellent H<sub>2</sub>sorption properties at moderate temperatures.
Metal nanocatalysis is an effective method to enhance the hydrogen storage properties of magnesium hydride (MgH2), and catalytic effect can be further improved by a matrix material supported nanometal. In this work, carbon nano-Ni (Ni@C) was synthesized calcination dimethylglyoxime dinickel chelate, then it doped into MgH2 improve de/rehydrogenation kinetics. This shows that homogeneously distributed Ni with refined particle size in base leads superior effects on absorption/desorption MgH2-5...
For the first time, few-layer Ti3C2Tx (FL-Ti3C2Tx) supporting highly dispersed nano-Ni particles with an interconnected and interlaced structure was elaborated through a self-assembly reduction process. FL-Ti3C2Tx not only acts as material but also self-assembles Ni2+ ions electrostatic interaction, assisting in of nano-Ni. After ball milling MgH2, Ni30/FL-Ti3C2Tx (few-layer supported 30 wt % via reduction) shows superior catalytic activity for MgH2. example, MgH2-5 can release approximately...
Two-dimensional Ti3C2Tx MXenes exposing different active facets are introduced into MgH2, and their catalytic effects systematically investigated in depth through experimental theoretical approaches. Excluding factors such as interlayer space, surface functional groups contingency, the exposed is considered to be dominant factor for activity of towards MgH2. More edge displays higher than that with more basal facets, which also leads rate-controlling steps MgH2 de/hydrogenation process. The...
To effectively address the kinetic sluggishness associated with MgH2, this study utilized Ti-EG-Ni dual-metal organic crystal as precursors and employed carburization to prepare unique rod-shaped structure TiO2/C/Ni. The catalyst was incorporated into MgH2 by ball milling, demonstrating excellent hydrogen storage performance. composite of MgH2-8 wt % TiO2/C/Ni exhibited a lower initial dehydrogenation temperature 185 °C marked activation energy 60.537 kJ/mol. At 300 150 °C, it only required...
Catalysts play an extraordinarily important role in accelerating the hydrogen sorption rates metal-hydrogen systems. Herein, we report a surprisingly synergetic enhancement of metal-metal oxide cocatalyst on properties MgH2: only 5 wt % doping Ni into ultrafine TiO2 enables significant increase desorption kinetics; it absorbs 4.50 even at low temperature 50 °C. The striking improvement is partially ascribed to formation particular Ni@TiO2 core-shell structure, thereby forming versatile...
Nano-dispersed Ni particles over mesoporous carbon material CMK-3 (Ni/CMK-3) was fabricated by means of impregnation-reduction strategy using precursor NiCl2 · 6H2O, which is beneficial to improving the de/rehydrogenation performances MgH2. The dehydrogenation onset temperature MgH2-Ni/CMK-3 significantly lowered 170 K from that pristine MgH2 (around 603 K). Totally 5.9 wt% hydrogen absorption capacity liberated within 1 h at a 423 under pressure 3 MPa. This composite can absorb 3.9 even 328...
