ABSTRACTMonolithic Mo oxide/polypyrrole hybrid aerogels and xerogels were successfully synthesized through sol-gel methods. The PPy formed appears to be β-substituted. A 100 fold increase in electrical conductivity was observed for the hybrids (4× 10–3 S/cm) as compared to the pristine MoO3 gels (2× 10–5 S/cm). An initial increase in Li+ intercalation capacity is also observed for the hybrid. The electrical conductivity and Li+ intercalation depend greatly on the concentration of Motrichloro alkoxide precursor and sol aging conditions. The hybrid aerogels have a density of 0.5 g/cc and a surface area of 120 m2/g. The as-formed gels are amorphous and crystallize to the orthorhombic MoO3 phase at 375°C.
