Effect of a mesoporous NiCo₂O₄ urchin-like structure catalyzed with a surface oxidized LiBH₄ system for reversible hydrogen storage applications

Abstract

Surface oxidized LiBH4/NiCo2O4 systems prepared by wet-impregnation method. LiBH4 + 75% NiCo2O4 released 5.8 wt% H2 at 250 °C in 60 min. The increased concentration of NiCo2O4 in all the systems impacts the active sites and H2 storage capacity.
