Microporous Carbonaceous Materials Incorporated with Metal (Ti, V and Zn) for Hydrogen Storage

Abstract

The present research work is focused on the development and characterization of light weight microporous carbonaceous material, such as graphite (53150 micron) incorporated with either titanium n-butoxide, titanium diisopropoxide bis (2,4-pentanedionate), vanadium 2,4-pentane-dionate or zinc 2,4-pentanedionate having varying wt% of the metal (28%) using 2-propanol/ethanol as solvent at 4050 °C. The calcination has been carried out at 100, 150 and 200 °C, except the samples with titanium diisopropoxide bis (2,4-pentanedionate) which are calcined at 80 °C. FESEM along with atomic absorption studies revealed that the maximum incorporation of metals (Zn, V and Ti) in graphite has been observed with 4 wt% of zinc 2,4-pentanedionate calcined at 100 °C, 4 wt% of vanadium 2,4-pentanedionate calcined at 100 °C, 4 wt% of titanium n-butoxide calcined at 100 °C and 2 wt% of titanium diisopropoxide bis (2,4-pentanedionate) calcined at 80 °C, and equilibration time of 20-24 h has been used in each case. These samples may be used for hydrogen storage.
