Effect of Vanadium Catalysts on Hydrogen Evolution from NaBH4

NaBH4 is a very cheap and hydrogen-rich material, as well potential hydrogen store. However, the high temperature of its thermal decomposition (above 530 °C) renders it inapplicable in practical use. Here, we studied effect addition diverse V-containing catalysts on desorption. It turns out that mechanochemical doping with vanadium metal, oxides, or nanoparticles lowers pyrolysis significantly. Notably, milled for 3 h 25 wt.% V2O5 VO2 releases ca. 70% stored range 370–450 °C. On other hand, precursors solvents used to prepare rather uniform (~4 nm) suspended THF less larger ones (~15 o- difluorobenzene have adverse purity evolved.
