It has been well known that doping nano-scale catalysts can significantly improve both the kinetics and reversible hydrogen storage capacity of MgH2. However, so far it is still a challenge to directly synthesize ultrafine (e.g., < 5 nm), mainly because complicated chemical reaction processes. Here, facile one-step high-energy ball milling process developed in situ form Ni nanoparticles from nickel acetylacetonate precursor MgH2 matrix. With combined action metallic expanded graphite (EG),...
Since the discovery of magnesium borohydride, its synthesis has predominantly relied on borane method or ion exchange to this day. However, these approaches have been hampered by use highly toxic, explosive, and expensive raw materials. In study, we reported a low-cost high-yield solvent-free Mg(BH4)2 (yield: ∼80%, time: 45 min) through dry mechanochemical reaction between MgH2 hydrated borate Zn2B6O11·3.5H2O at room temperature. Unlike traditional focus triggering role transition metal rare...
Lithium borohydride (LiBH4) is a promising hydrogen storage material, but the irreversibility of hydrolysis and high cost regeneration have severely restrained its commercial applications. Herein, we reported cost-effective method to regenerate LiBH4 by ball milling hydrous lithium metaborate (LiBO2·2H2O) with low-cost Mg-based alloys, instead MgH2, under ambient conditions. An effective strategy developed improve kinetics introducing light rare-earth metals into Mg facilitate breakage B–O...
