AB  - The influence of chronopotentiometry response on the morphology and structure of galvanostatically synthesized tin dendriticparticles has been investigated. Sn dendrites were electrodeposited at the current density 1.5 times larger than the limiting diffusioncurrent density (− 3 mA cm−2) with various amounts of the electricity (200 and 400 mC), and the obtained morphologyand structure of the particles were characterized by SEM and XRD techniques, respectively. The strong effect of the amountof spent electricity on the morphology and structure of the particles was observed, and it is explained by morphological andstructural analysis of Sn particles produced potentiostatically at various cathodic potentials selected to be in line with therecorded chronopotentiometry response. The strong correlation among chronopotentiometry response, morphology, andstructure of the Sn dendrites was established. The spear-like and the dendrites with prismatic branches possessed the strong(200),(400) preferred orientation, and they were obtained with a chronopotentiometry response of about − 1200 mV vs. Ag/AgCl. The chronopotentiometry responses in the − 1210 ÷ − 1740 mV vs. Ag/AgCl range caused a formation of the fern-likedendrites with the strong (220),(440) preferred orientation. Based on the obtained results, it follows that the chronopotentiometryanalysis represents good diagnostic criteria for obtaining Sn powder particles of desired morphology and structure.

AB  - In order to achieve widespread application of fuel cell technology, the development of an efficient and economical catalyst is a crucial step. Reducing the diameter of catalyst particles, producing particles with a specific orientation surface, and alloying noble metals with less expensive metals are possible approaches to improve catalyst performance. This study will be focused on novel ways for creating PtSnZn catalysts that are more effective for the anodic reactions in fuel cell such are methanol, ethanol and formic acid oxidation reactions. PtZn and PtSnZn nanoparticles were produced using the microwave assisted polyol method and were supported on high surface area carbon Vulcan XC-72R material. The electrochemical behavior of synthesized catalysts was investigated utilizing the cyclic voltammetry, chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission electron microscopy analysis (TEM), and thermogravimetric analysis (TGA) were used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the benefits of microwave synthesis and carefully adjusted metal alloying.

AB  - Tin dendrites found wide application in various industries.1 They can be obtained by both non-electrochemical and electrochemical methods of synthesis. In this study, they were produced by a galvanostatic regime of electrolysis from alkaline hydroxide solution at a current density of –3 mA cm–2 , 1.5 times larger than the limiting diffusion current density, with an amount of the electricity of 200 and 400 mC. In the dependence of an amount of the passed electricity, Sn dendrites of various morphology and crystal orientation were obtained: the fern-like dendrites predominantly oriented in (220), (440) crystal planes are obtained with 200 mC and the spear-like and the dendrites with prismatic branches showing the strong (200),(400) preferred orientationwere obtained with 400 mC. The strong correlation between morphology and structure of Sn dendrites is established and it can be explained by analysis of chronopotentiometry response obtained at the given current density and by morphological and structural analyses of Sn dendrites obtained by a potentiostatic regime at cathodic potentials corresponding to values attained after the passed amount of the electricity of 200 and 400 mC. The chronopotentiometry response after spent 200 mC was dominantly in the (–1600 – 1740) mV vs. Ag/AgCl range, and the fern-like dendrites with the strong (220), (440) preferred orientation were obtained in this potential range. After spent 400 mC, the chronopotentiometry response was about –1200 mV vs. Ag/AgCl, and the spear-like and the dendrites with prismatic branches with the strong (200),(400) preferred orientationwere obtained at this cathodic potential.

AB  - The formation of tin dendritic nanostructures by electrolysis from the alkaline electrolytehas been investigated. Morphology and structure of Sn dendrites produced applying both potentiostatic and galvanostatic regimes of the electrolysis are characterized by SEM and XRD, respectively. Depending on the applied cathodic potentials, three types of Sn dendrites were obtained: (a) needle like and spear-like, (b) fern-like, and (c) stem-like dendrites. The very branchy dendrites with branches of the prismatic shape obtained by the galvanostatic regime of electrolysis represented anovel type of Sn dendrites, not previously reported in the literature. To explain the formation ofvarious dendritic forms, correlation with the polarization characteristics for this electrodepositionsystem is considered. The needle-like and the spear-like dendrites represented monocrystals of(200),(400) preferred orientation, the fern-like dendrites exhibited the predominant (220),(440) preferredorientation, while in the stem-like particles Sn crystallites were oriented to a greater extent inthe (440) crystal plane than in other planes. The galvanostatically synthesized Sn particles possessed the strong (200),(400) preferred orientation. The strong influence of parameters and regimes ofelectrodeposition on structural characteristics of Sn dendrites is explained by the fundamental lawsof electrocrystallization taking into consideration the concept of slow-growing and fast-growingcrystal planes.

AB  - Bacterial nanocellulose, BNC, has emerged as a new class of nanomaterials recognized as renewable, biodegradable, biocompatible and material for versatile applications. BNC also proved as a perfect support matrix for metallic nanoparticle synthesis and appeared as suitable alternative for widely used carbon based materials. Following the idea to replace commonly used carbon based materials for platinum supports with the green and sustainable one, BNC appeared as an excellent candidate. Herein, microwave assisted synthesis has been reported for the first time for platinum nanoparticles supported on BNC as green material. Bacterial nanocelullose-platinum catalyst, Pt/BNC, was investigated by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), atomic force microscopy (AFM), X-ray diffractometry (XRD) and transmission-electron microscopy (TEM) analysis. The obtained results confirmed successful synthesis of new Pt-based catalyst. It was found that Pt/BNC catalyst has high electrocatalytic performance in methanol oxidation reaction. Green/sustainable catalytic system is highly desirable and provided by the elegant microwave assisted synthesis of Pt/BNC will pave the way for a larger scale application and expedite the market penetration of such fuel cells.

AB  - Bacterial nanocellulose (BNC) has gain on its popularity in the last decades and it has attracted a contemporary research interest as a promising material suitable for different applications (in medicine as a material for biomedical implants or scaffolds, in pharmacy as controlled release drug carriers, in industry as barriers, membranes, and absorbers, and electronics. BNC is hydroxyl group rich biopolymer which further provides various possibilities for modifications and the production of composites. Poly(vinyl alcohol), PVA, polymer of excellent film forming capacity, high thermal stability, flexibility, good chemical resistance, and mechanical properties has been recognized as promising material for BNC/PVA composite preparation. PVA is chemically compatible with BNC, due to their polarity and large amount of hydroxyl groups forming strong inter-molecular hydrogen bonds. The main objective of this work was to prepare new platinum supported catalyst on BNC/PVA composite as nanoparticles carrier, designed for electrocatalytic applications. For that purpose, BNC/Pt suspension was mixed with 1 wt% PVA solution and BNC/PVA/Pt catalyst in the form of film was successfully synthesized. The structure and thermal properties of catalyst were characterized by ATR-FTIR and TG analysis, respectively, while its crystallinity was investigated by XRD analysis. Electrocatalytic potential of BNC/PVA/Pt catalyst was tested in methanol oxidation reaction. Remarkable catalytic activity of new Pt based catalyst was confirmed. The obtained results for catalyst activity was comparable to those obtained for preferentially used carbon based Pt supports pointing that BNC based composited can be considered as great substitution of carbon based materials with the green one.
