On-site on-demand hydrogen generation from a new Mg–LiBH 4 –AlCl 3 system has been established. The hydrogen yield, mHGR (maximum hydrogen generation rate) and reaction stability can be adjusted by changing the samples' compositions, milling time and water/mixture ratios. The Mg-9 wt.%LiBH 4 -1 wt.%AlCl 3 composite reaches a conversion yield of 87%, corresponding to...
OL (Oleic acid)–Cobalt–Lanthanum–Zirconium–Boron nanoparticle was synthesized by chemical reduction of chloride salts of metals in the presence of oleic acid as stabilizing agent. The obtained materials were characterized by XRD (X-ray diffraction), TEM (Transmission electron microscopy), ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy), BET (Brunauer–Emmett–Teller) and UV–vis (Ultraviolet–visible)...
Here, we report for the first time the use of p(AAc (p(acrylic acid)) cryogel for in situ metal nanoparticle preparation, and their use as a superporous reactor for H 2 generation from hydrolysis of NaBH 4 . Superporous p(AAc) cryogels and conventional hydrogels were prepared via free radical polymerization technique at low (−18 °C) and moderate (40 °C) temperatures, respectively....
Borohydride has been considered as a potential fuel for the fuel cell application due to its high energy density. A DBFC (direct borohydride fuel cell) is an electrochemical device that converts chemical energy stored in borohydride and oxidant directly to electrical energy as long as the fuel and oxidant is supplied. One of the main problems encountered in a DBFC is the simultaneous hydrolysis of...
The hydrolysis of aluminum powder can be efficiently improved by milling with hydrides, among which LiH performs the best. Both sample composition and milling time affect the hydrolysis of Al–LiH mixture. Reaction temperature has a great impact on improving the hydrolysis properties. The reactions taken place in the solution are studied and the formation of the LiAl 2 (OH) 7 hydrate...
Hydrogen was generated from ammonia borane complex by hydrolysis using cobalt nanocluster catalyst supported on polydopamine functionalized MWCNTs (multi-walled carbon nanotubes). The impregnation-chemical reduction method was used for the preparation of the supported catalyst. The nanocluster catalyst support was formed by in-situ oxidative polymerization of dopamine on the MWCNTs in alkaline solution...
