Abstract
One of the biggest problems in using hydrogen as an alternative fuel is that its
storage must be safe and portable. This work addresses a new direct synthesis
technique used to obtain a novel mesoporous carbon (CMK-3) modified with
zirconium oxide. This novel material shows promise for hydrogen adsorption and
storage application for energy harvesting. Zirconium oxide (Zr-CMK-3) material is
achieved through successful synthesis and characterized by XRD, SEM,Raman,
BET, UV-Vis-DRS, XPS and TEM analyses. Zr-CMK-3 signifi- cantly improved
H2 storage performance (reaching at 77 K and 10 bar 4.6 wt%) comparedto the
pristine CMK-3. The novel material is favorable for H2 uptake by using weak
bonding (physisorption). A hydrogen uptake mechanistic approach is proposed and
the role of the Zr+4
cation in hydrogen adsorption is discussed.
