High catalytic performance of Pt nanoparticles via support of conducting polymer for electrooxidation of methanol at carbon ceramic electrode

Synthesis of silver-anchored polyaniline–chitosan magnetic nanocomposite: a smart system for catalysis

“…[22][23][24] PANI has a special position among these polymers due to its unique properties such as ease of preparation, high conductivity, chemical and environmental stability under ambient conditions, low operational voltage in addition to its unique redox properties 25,26 which result in directing the research in the last years, to use PANI for different applications especially as catalyst supports. [27][28][29][30][31][32][33] Researchers face a great problem during the separation of the products from the reaction medium; the traditional routes were ltration or centrifugation (especially for nanometer-scaled materials), which are time and energy consuming. 34,35 Magnetic separation is one of the most promising techniques in separation that has excellent advantages over other methods including high speed, accuracy, ease of control as well as simplicity.…”

Synthesis of MCM-41 nanoparticles from stem of common reed ash silica and their application as substrate in electrooxidation of methanol

“…When the concentration of methanol increases, peak p 2 grows noticeably and current of anodic peak p 1 does not show significant increment. At high methanol concentration, more NiOOH species are converted to β-Ni(OH) 2 through the methanol oxidation and more β-Ni(OH) 2 species are available in oxidation process according to equation (8) [45]:…”

“…where P ox defines the eventual products of methanol oxidation such as carbonate, formaldehyde and formate anion [21,50]. The equations (8) and 9show an EC mechanism which can be described according to the following reactions:…”

“…One of the main drawbacks of DMFC is slow kinetics of the methanol oxidation reaction at the anode due to production of intermediate species and poisoning of the catalysts, which can lead to high overpotentials and limitation in the performance of DMFCs. Noble metals, binary or ternary alloys and their composite such as Pt-Ru [3], Pd-Fe [4], Pt-Sn [5], Au-Pt [6], Pt-Cu [7], Pt-polyaniline [8] and Ru-deposited NiZn [9] Electronic supplementary material: The online version of this article (https:// doi.org / 10.1007/ s12034-018-1580-8) contains supplementary material, which is available to authorized users.…”
