Characterization of Multiphase Polypyrrole/Vanadium Oxide
Vanadium oxide Phase-1 and Phase-2 nano powers were synthesized from vanadium pentoxide in the presence of glucose using hydrothermal technique. The polypyrrole/vanadium oxide (PV P-1 and PV P-2) nano composites were synthesized with 15 30 45 and 60 weight percents of vanadium oxide Phase-1 and Phase-2 in pyrrole by the chemical polymerization (oxidation) method.

Material characterization is a crucial step to ensure the characteristics and properties of the samples are comparable to the standard adsorbent and suitable for CO2 adsorption. The objective of this work is to characterize natural calcium based materials for CO2 adsorption which are obtained from waste cockle shells. Characterization analyses are conducted by using XRD BET and FESEM.
