Platinum electrocatalysts were prepared using PtCl4 as a starting material and 1-decylamine, N,N-dimethyldecylamine, 1-dodecylamine, N,N-dimethyldodecylamine, 1-hexadecylamine, and 1-octadecylamine as surfactants. These surfactants were used for the first time in this synthesis to determine whether the primary and/or tertiary structure and/or chain length of the surfactants, affects the size and/or activity of the catalysts in C-1-C-3 alcohol electro-oxidation reactions. Electrochemical measurements (cyclic voltammetry and chronoamperometry) indicated that the highest electrocatalytic performance was observed for the Pt nanocatalysts that were stabilized by N,N-dimethyldecylamine, and this has a tertiary amine structure with a short chain length (R = C10H21). The high performance may be due to the high electrochemical surface area, Pt(0)/Pt(IV) ratio, %Pt utility, and roughness factor (R (f)). X-ray photoelectron spectroscopy, X-ray diffraction, atomic force microscopy, and transmission electron microscopy were used to determine the parameters that affect the catalytic activities.

Multichromic polymers of benzotriazole derivatives: Effect of benzyl substitution
Yigitsoy, Basak; Karim, S. M. Abdul; Balan, Abidin; Baran, Derya; Toppare, Levent Kamil (Elsevier BV, 2011-02-01)
Two electroactive monomers 1-benzyl-4,7-di(thiophen-2-yl))-2H-benzo[d][1,2,3]triazole (BBTA) and 2-benzyl-4,7-di(thiophen-2-yl))-2H-benzo[d][1,2,3]triazole (BBTS) were synthesized with satisfactory yields. The effect of substitution site on electrochemical and optical properties was investigated with cyclic voltammetry and spectroelectrochemical studies. Results showed that position of pendant group alters the electronic structure of the resulting polymer causing different optical and electrochemical behavi...
Electrochemical investigation of copper-DTPI interactions
Hicyilmaz, C; Altun, Naci Emre (Springer Science and Business Media LLC, 2006-05-01)
The electrochemical behavior of copper in the absence and presence of a dithiophosphinate type collector, sodium diisobuthyldithiophosphinate (NaDTPI), was determined to investigate the interactions between a copper surface and NaDTPI as a function of pulp potential (Eh) and pH. The electrochemical studies were performed by Cyclic Voltammetry (CV) in the -355 to +1550 mV (SHE) potential range and at different pHs from slightly acidic to strongly alkaline conditions. The electrochemical studies were carried ...
Electrochemical and optical properties of novel terthienyl based azobenzene, coumarine and fluorescein containing polymers: Multicolored electrochromic polymers
Yigit, Deniz; Udum, Yasemin Arslan; GÜLLÜ, Mustafa; Toppare, Levent Kamil (Elsevier BV, 2014-01-01)
Three electroactive terthienyl based monomers, namely 1-phenyl-2-[4-(2,2':5',2 ''-terthien-3'-ylmethoxy)phenyl]diazene (TTAz), 4-(2,2':5',2 ''-terthien-3'-ylmethoxy)-2H-chromen-2-one (TTCo) and methyl 2-[3-oxo-6-(2,2':5',2 ''-terthien-3'-ylmethoxy)-3H-xanthen-9-yl] benzoate (TTFlo), were synthesized with good yields and their conducting polymers were electrochemically prepared on ITO electrode surfaces. The effect of chromophore type on electrochemical and optical properties of the polymers was investigated...
Electrochemical copolymerization and characterization of dianilines linked by polyether bridge with aniline
TİRKEŞ, SEHA; Önal, Ahmet Muhtar (Springer Science and Business Media LLC, 2010-04-01)
Copolymer of aniline and triethylene glycol bis(o-aminophenyl) ether was synthesized by constant potential electrolysis. Cyclic voltammogram of the copolymer films recorded in the monomer-free electrolytic solution revealed that the redox behavior of the films approaches to that of poly(triethylene glycol bis(o-aminophenyl) ether) with increasing amount of triethylene glycol bis(o-aminophenyl) in the feed ratio. Copolymerization was investigated by in situ recording the changes in the electronic absorption ...
New, highly stable electrochromic polymers from 3,4-ethylenedioxythiophene-bis-substituted quinoxalines toward green polymeric materials
Durmus, Asuman; Günbaş, Emrullah Görkem; Toppare, Levent Kamil (American Chemical Society (ACS), 2007-12-11)
Two new highly stable electrochromic polymers, poly(5,8-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2,3-di(thiophen-2-yl)quinoxaline) (PDETQ) and poly (5,8-bis(2,3 -dihydrothieno[3,4-b][ 1,4]dioxin-5yl)quinoxaline) (PDEQ) were synthesized, and their potential use as neutral state green polymeric materials was investigated. Spectroelectrochemistry showed that both polymers reveal two distinct absorption bands as expected for this type of donor-acceptor polymer, at 410 and 660 nm for PDEQ and 405 and 780 nm...
