“…642 An efficient degradation is also achieved using carbonaceous WO 3 /TiO 2 composites with PANi and PPy due to their higher porosity, better charge separation, and photoresponse range extension induced by a synergistic effect of PANi/PPy, WO 3 , and TiO 2 . 646 In addition to the use of TiO 2 as a photocatalyst, other inorganic oxides are used as well. For example, a ZnO composite with the poly(aniline-co-o-aminophenol) [poly(ANIco-oAP)] conducting copolymer is an efficient photocatalyst for MB degradation.…”

Conducting polymers (CPs), thanks to their unique properties, structures made on-demand, new composite mixtures, and possibility of deposit on a surface by chemical, physical, or electrochemical methodologies, have shown in the last years a renaissance and have been widely used in important fields of chemistry and materials science. Due to the extent of the literature on CPs, this review, after a concise introduction about the interrelationship between electrochemistry and conducting polymers, is focused exclusively on the following applications: energy (energy storage devices and solar cells), use in environmental remediation (anion and cation trapping, electrocatalytic reduction/oxidation of pollutants on CP based electrodes, and adsorption of pollutants) and finally electroanalysis as chemical sensors in solution, gas phase, and chiral molecules. This review is expected to be comprehensive, authoritative, and useful to the chemical community interested in CPs and their applications.

“…This result was because the high concentration of methyl orange can reduce light penetration and absorption by the catalysts. High concentration of methyl orange reduced the generation of hole-electron and slowed down the photodegradation activities [ 16 , 17 ]. The low concentration of dye solution of 5 ppm showed a slightly decreased reaction.…”

“…In order to synthesis CNC, the source of carbon which is polyaniline (PANi), polypyrrole (PPy) and poly vinyl acetate (PVAc) must undergo polymerization process. The polymer of PANi and PPy was obtained by using chemical oxidative method [34]. Meanwhile, the polymer of PVAc was directly used by dissolving this polymer with dimethylformamide (DMF) for 1 h at a temperature of 600°C and was continuously stirred for 12 hrs [35].…”

A new type of support which is carbon nanocage (CNC) has been introduced and synthesized by pyrolysis method using MgO metal as the template of CNC. Three types of polymers which are PANi, PPy and PVAc have been chosen as carbon source for the CNC production that synthesized at temperature range of 600-900 o C, under N2 gas flow. All synthesized CNCs were characterized using TEM analysis to study their morphologies. From TEM characterization, the best CNC will be doped with Pt-Ru catalyst for the electrochemical test and DMFC performance. Based on XRD analysis, the estimated particle size of Pt-Ru/CNC obtained is smaller than commercial carbon black support, Pt-Ru/C. In BET analysis, the surface area of CNC support and Pt-Ru/CNC are 416 m 2 g-1 and 154.53 m 2 g-1 respectively, which consider a high surface area and good property as a catalyst. In electrochemical evaluation of cyclic voltammetry, the Pt-Ru/CNC electrocatalyst shows higher electrochemical surface active (ECSA) value than Pt-Ru/C, which are 16.9 m 2 g-1 and 6.2 m 2 g-1 , respectively. This result indicates that the ECSA value of Pt-Ru/CNC 1.7 times larger than Pt-Ru/CNC. Meanwhile, from the DMFC-single cell test, the Pt-Ru/CNC with 40 % (catalyst wt. %) achieved more than 6.0 mW cm-2 of power density performance, which is higher than the Pt-Ru/C. These results can be attributed to the high BET surface area of CNC support and Pt-Ru on CNC support. It can be concluded that Pt-Ru supported CNC is a superior candidate for future DMFC anode electrocatalyst.
