Catalytic conversion of ethyl alcohol on polyaniline protonated with 12-tungstosilicic acid

Acidic nickel salts of Keggin type heteropolyacids supported on SBA-15 mesoporous silica

“…Among the supports that have been mentioned in different papers are: salts of heteropolyacids [6,7], Electronic supplementary material The online version of this article (doi:10.1007/s10934-015-0072-0) contains supplementary material, which is available to authorized users. zeolites [8], mesoporous silica [9][10][11], titania [12,13], active carbon [14,15], polymeric materials [16,17] and different molecular sieves: MCM-41, SBA-15, SBA-3, HMS [18][19][20][21][22][23][24][25][26][27][28]. Mesoporous molecular sieves such as SBA-15, highly stable and with better textural properties compared to other supports seem to be suitable for depositing HPA.…”

Synthesis of tri(hydroxyphenyl)methane using polyaniline‐p‐toluenesulfonic acid salt

“…1,2 Pron and coworkers have used heteropolyanions, which were incorporated into conjugated polymer matrices via chemical doping. [3][4][5] Pielichowski and Iqbal 6 have developed efficient catalysts for the oxidation of aromatic hydrocarbons, alcohols and alkenes with high efficiency at relatively low temperatures. Further research on application of catalysts based on polyaniline salts in oxidation reactions was continued by Das, Iqbal, and coworkers.…”

Synthesis and properties of polyaniline doped with iron-substituted silicotungstate isomers with Keggin structure

“…Usually, the conductivity of polyaniline doped with HPA is 10 À3 -10 À6 S cm À1 [17]. In order to investigate the effects of iron-substituted silicotungstate isomers on conductivity of the polyaniline, we measured the conductivity of SiW 11 Fe/PANI using a standard four-probe technique.…”
