In situ synthesized heteropoly acid/polyaniline/graphene nanocomposites to simultaneously boost both double layer- and pseudo-capacitance for supercapacitors
It is challenging to simultaneously increase double layer- and pseudo-capacitance for supercapacitors. Phosphomolybdic acid/polyaniline/graphene nanocomposites (PMo 12 -PANI/GS) were prepared by using PMo 12 as a bifunctional reagent for not only well dispersing graphene for high electrochemical dou...
