Size-dependent electrocatalytic reduction of nitrite at nanostructured films of hollow polyaniline spheres and polyaniline–polystyrene core–shells

Conducting Polymers

“…Poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) composite in combination with graphite-poly(dimethylsiloxane) was fabricated and applied as flexible microelectrode arrays for the capture of cardiac and neuronal signals in vivo [960]. Nanostructured films of hollow polyaniline and PANI-polystyrene core shells were prepared by template synthesis [990]. Polyaniline was synthesized within the pores of poly (vinylidene flouride).…”

Conducting Polyaniline Nanowire Arrays Modified Electrode for High Performance Supercapacitor and Enhanced Catalysis of Nitrite Reduction

“…Kazimierska et al . concluded that electrodes modified with PANI nanostructures displayed higher effective surface areas, improved mass transport, and higher catalytic effect and control over the local microenvironment compared to that of electrodes modified with PANI microstructures . These better performances were explained by the redox and ion exchange properties of the conducting polymers, allowing the exchange between the hydroxides produced and the dopant anion of the conducting polymer .…”

“…These better performances were explained by the redox and ion exchange properties of the conducting polymers, allowing the exchange between the hydroxides produced and the dopant anion of the conducting polymer . Recently, different kinds of electrochemical sensors, basing on the PANI film modification of electrodes, have been developed to determine nitrite . However, the studies on the large arrays of PANI nanowires are still rarely reported for high performance supercapacitors and enhanced electrocatalytic reduction of nitrite simultaneously.…”

Electrochemical Preparation of a Nanostructured Poly(amino napthalene sulfonic acid) Electrode Using CTAB as a Soft Template and Its Electrocatalytic Application for the Reduction of Iodate

“…Meanwhile, there are numerous literature sources describing the soft template based electrochemical synthesis of nCPs [8][9][10][11][12], even so, electrochemical synthesis of nCPs using CTAB remains unique. Very recently, Li et al [13] synthesized poly(3,4-ethylenedioxythiophene) (PEDOT) micro/nanorods using CTAB as a soft template by electrochemical method.…”
