In this study, platinum nanoparticles have been prepared using PtCl4 as a starting material and 1-hexylamine, N-methylhexylamine, N,N-dimethylhexylamine, 1-heptylamine, N-methylheptylamine, and N, N-dimethylheptylamine as surfactants. All these surfactants were used in this synthesis, for the first time, to explore the effect of primary, secondary, and tertiary amine and chain length on the size and catalytic activity toward C1-C3 alcohol electro-oxidation. The electrochemical performance of all catalysts was determined using cyclic voltammetry and chronoamperometry. These techniques indicate that the highest electrocatalytic performance was generally observed when electrochemical surface area (ECSA), percent platinum utility, roughness factor, and the number of CH3 groups attached to the nitrogen atom is higher and the chain length shorter (C6H13). In addition, other important properties such as the crystal structure of platinum, size, and distribution of the platinum nanoparticles on the carbon support, and Pt(0) to Pt(IV) ratio, were determined using X-ray photoelectron spectroscopy, X-ray diffraction, atomic force microscopy, and transmission electron microscopy. It was found that increasing ECSA, Pt(0)/Pt(IV) ratio, % Pt utility, and roughness factor improves the C1-C3 alcohol oxidation catalytic performance.

Platinum nanocatalysts prepared with different surfactants for C1-C3 alcohol oxidations and their surface morphologies by AFM
Ertan, Salih; Sen, Fatih; Sen, Selda; Gökağaç Arslan, Gülsün (2012-06-01)
In this study, platinum nanoparticle catalysts have been prepared using PtCl4 as a starting material and 1-octanethiol, 1-decanethiol, 1-dodecanethiol, and 1-hexadecanethiol as surfactants for methanol, ethanol, and 2-propanol oxidation reactions. The structure, particle sizes, and surface morphologies of the catalysts were characterized by X-ray diffraction (XRD), atomic force microscopy and transmission electron microscopy (TEM). XRD and TEM results indicate that all prepared catalysts have a face-centere...
Efficiency enhancement of methanol/ethanol oxidation reactions on Pt nanoparticles prepared using a new surfactant, 1,1-dimethyl heptanethiol
Sen, Fatih; Sen, Selda; Gökağaç Arslan, Gülsün (2011-01-01)
In this study, carbon-supported platinum nanoparticle catalysts were prepared using PtCl(4) and H(2)PtCl(6) as starting materials and 1-heptanethiol, 1,1-dimethyl heptanethiol, 1-hexadecanethiol and 1-octadecanethiol as surfactants. These nanoparticles can be used as catalysts for methanol and ethanol oxidation reactions in methanol and ethanol fuel cells. 1,1-Dimethyl heptanethiol was used for the first time in this type of synthesis; other surfactants were used to synthesize nanoparticles for comparison o...
Preparation of iron oxide nanoparticles by microwave synthesis and their characterization
Acarbas, Ozge; Ozenbas, Macit (American Scientific Publishers, 2008-02-01)
In this study production of fine particle Fe2O3 via microwave processing of Fe(NO3)(3)center dot nH(2)O followed by low temperature annealing was reported. XRD was used to characterize the structural properties of nanoparticles. Approximate particle sizes were between 3-13 nm according to Scherrer's equation. Single point BET measurement results also show that samples have large surface area and they are nanometer sized particles. TEM study was conducted to examine the structure of the nanoparticles. TEM fi...
Alkaline Hydrothermal Synthesis, Characterization, and Photocatalytic Activity of TiO2 Nanostructures: The Effect of Initial TiO2 Phase
Erdogan, Nursev; PARK, JONGEE; Choi, Woohyuk; Kim, Soo Young; Öztürk, Abdullah (American Scientific Publishers, 2019-03-01)
One-dimensional (1D) titanate nanostructures were synthesized by hydrothermal route, using commercially available TiO2 (P25) and anatase powders as precursor materials and strong NaOH solution as catalyzer. The prepared titanates were calcined, followed by protonation to produce TiO2 nanostructures having enhanced photocatalytic and photovoltaic properties. The synthesized TiO2 1D nanostructures were characterized using field-emission scanning electron microscope, high-resolution electron microscope, X-ray ...
Development of sensitive analytical methods for the determination of thallium at trace levels by slotted quartz tube flame atomic absorption spectrometry
Ari, Betul; BAKIRDERE, Sezgin; Ataman, Osman Yavuz (Elsevier BV, 2020-09-01)
A simple, sensitive and economical technique is needed for the determination of thallium and this study demonstrates the different analytical strategies were developed using atomic absorption spectrometry (AAS). In order to improve the sensitivity of flame atomic absorption spectrometry (FAAS), a basic slotted quartz tube (SQT) was used for the thallium determination. In the first strategy, mixing propanol (100 mu L) and Tl standard solution (500 mu L) under the optimum conditions, namely solvent assisted S...
