Li4Zn3B4O11/Li2B2O4 Nanocomposites as a Potential Electrode Material for Electrochemical Hydrogen Storage; Insight of Fabrication and Morphology Controlling

Comparison of Hydrogen Powertrains with the Battery Powered Electric Vehicle and Investigation of Small-Scale Local Hydrogen Production Using Renewable Energy

“…One of the main problems is the fact that hydrogen only attaches to reactive carbon [19]. This is why current research focuses on either creating more reactive carbon sites or coating carbon with materials that act as catalysts [20][21][22][23][24]. One of the highest storage capacities currently reported for this technology is 10.94 wt.% (3.6 kWh/kg) at room temperature, which was achieved by coating carbon nanotubes with bimetallic iron silver and titanium oxide particles.…”

Strong Interfacial Coupling of Tunable Ni–NiO Nanocomposite Thin Films Formed by Self-Decomposition

“…Toward the realization of new spintronics devices, solid-state fabrication techniques including nanolithography and thin-film deposition produce reliable and durable materials. Among the conventional synthesis methods, chemical or solution-based growth techniques pave the way for extensive morphological tuning of functional nanostructures, − while physical methods, such as pulsed laser deposition (PLD) technique, have demonstrated its unique advantages in fabricating vertically aligned FM–AFM nanocomposites (VANs) that possess perpendicular exchange bias effect. For example, FM lanthanum strontium manganite (La 1 –x Sr x MnO 3 or LSMO) perovskite oxide has been coupled with AFM oxides such as NiO, BiFeO 3 , and LaFeO 3 . − Such self-assembly process is realized by the variations of nucleation property between the two constituent phases, i.e., the matrix phase favors the layered growth mode while the pillar phase favors the islanded growth mode. − The vertically aligned cylindrical nanopillars can be well coupled with the matrix phase, the aspect ratio and density can be tailored by varying the growth parameters or the target ratio, and so do their magnetic properties and exchange bias coupling properties .…”

Preparation and study of characteristics of LiCoO2/Fe3O4/Li2B2O4 nanocomposites as ideal active materials for electrochemical hydrogen storage

“…The important factor for the selection of the central metal is the ability to change the oxidation number in the redox process during electrochemical charge and discharge. [11][12][13][14][15] In the recent study, the ternary nanocomposites of LiCoO 2 / Fe 3 O 4 /Li 2 B 2 O 4 were designed by the one-step Pechini procedure by changing the operational synthesis parameters to achieve an ideal morphology. The ideal morphology of rod-shape in the nano-scale was achieved using citric acid and compared with the bulk structures in terms of electrochemical hydrogen sorption properties.…”
