Preparation of polyaniline–tin dioxide composites and their application in methanol electro-oxidation

Platinum(0)‐1,3‐divinyl‐1,1,3,3‐tetramethyldisiloxane Complex as a Pt Source for Pt/SnO2 Catalyst

“…In the synthesis method used for preparation, decomposition of metal precursor and formation of nanocrystalline SnO 2 occur simultaneously. The use of Pt divinyl complex instead of H 2 PtCl 6 [27] significantly affects the size of metallic Pt clusters. The use of hexachloroplatinic acid and incipient wetness impregnation method results in Pt crystallites larger than 2.5 nm [28,29] at the same loads.…”

“…It seems that the decrease in electrocatalytic activity observed above 460 K is related to changes in SnO 2 support, not to change in Pt dispersion. In many electrocatalytic processes, the role of structural factors such as nanoparticles orientation in catalytic activity was noticed [27]. The minimal electrocatalytic activity observed at circa 580 K corresponds to the maximal mass loss from DTG curves (Figure 8).…”

“…This temperature range overlaps with the end of gel support formation (end of clear mass loss). The observed increase in activity can be caused by formation of a system in which the support phase starts to play an important role in electrocatalytic activity by increasing the electronic conductivity of the catalytic layer [27].…”

Fe-N-C Electrocatalysts for Oxygen Reduction Reaction Synthesized by Using Aniline Salt and Fe 3+ /H 2 O 2 Catalytic System

“…1,2 Polyaniline (PANI), polypyrrole and polythiophene have been suggested as active electrode materials in fuel cells, primary and secondary batteries, and supercapacitors. 3,4 Among these polymers, polyaniline in particular has attracted much attention. 5 Recent studies have shown the crucial role of nitrogen precursors as primary hosts of active sites for high ORR when they were pyrolyzed on carbon matrix at high temperature.…”

Synthesis, Preparation, and Performance of Blends and Composites of π-Conjugated Polymers and their Copolymers in DMFCs

“…In the last five years a number of metal and metal oxide catalysts on p-CPs based supports have been tested for their efficiency towards methanol oxidation reaction and oxygen reduction reaction. [140][141][142][143][144][145][146] The results obtained from these studies were attributed to the efficiency of the catalyst systems; therefore, the role of the support matrices was not major. We are, therefore, not discussing these works in details, and will concentrate only on the reports where supports played major roles.…”
