Research paper thumbnail of Clean Energy from Ethanol: Efficient Oxidation of Ethanol in Solid Oxide Fuel Cell Via a New Reformer Catalyst

Commercial platinum nano catalysts do not facilitate a complete oxidation of ethanol. Ternary PtRhSnO2 catalysts are able to split the C-C bond and oxidize ethanol to CO2at room temperature [1- 2], but require further development. In order to improve the efficiency of high-temperature solid oxide fuel cells (SOFCs), particularly those utilizing ethanol as a fuel (ESOFC), our recent research focused on the catalysts that increase the power density of such fuel cells. The systems studied were based on nano-oxides such as SnO2, SnO2/Sb2O5, CeO2 and TiO2. The structural properties of such synthesized oxides were evaluated using XRD and HRTEM. These oxides were then deposited on nickel foam and used in an external reformer converting ethanol to H2. Reformed ethanol was fed to an anode of the SOFC . The Ni/CeO2catalyst in the external reformer, combined with SOFC, gives the highest power density of ESOFC (Ethanol Solid Oxide Fuel Cell). [1] Kowal A., et al., Nature Materials , 2009, 9, 325.

The examined samples were obtained in a complex process of sediment collection from Lake Swarzędzkie located in the region of Wielkopolska, Poland, followed by granulometric analysis by sieving and quartz grain shape analysis, with preparation of geotechnical sheets. The works involved the examination of physico-chemical characteristics of carbonate lake sediments and the analysis of impact of the sediments’ depth extraction on their chemical composition and physico-chemical properties. The lake sediment consists mainly of calcium carbonate (CaCO3) and can be a potential filler for plastics. Tests were carried out to determine chemical composition of the sediments and their thermal stability. The thermogravimetric analysis showed the three stages of the thermal decomposition. Sediments in deeper layers of the lake are characterised by the presence of not only...

Platinum was introduced by surface impregnation. Main goal of the research was to check an influence of metallic component (platinum) on sorption properties of B2O3/Al2O3 binary oxides. The oxide systems were characterized using XRD and TEM. Hydrogen adsorption was tested in the volumetric system and TPD measurements were taken. Results show that the amount of adsorbed hydrogen depends not only on the amount of platinum in the system but also on the type of oxide support and mainly on the content of boria.

Research paper thumbnail of Metallic Calcium as a Precursor for Sol-Gel Synthesis of CaCO3-SiO2 and CaO-SiO2 Systems

Ceramics, 2021

Upon calcination, a side effect of wollastonite formation as a result of the reaction between the components of the material has been observed in the two calcium-richest systems. The increase in calcium content produces an effect of porosity promotion. At high calcium contents, the homogeneity of the systems is limited by the ability of silica to disperse the calcium component. The properties of these systems are determined by the silica surface coverage with a large amount of the scattered CaCO3 fine microcrystallites (calcite), resulting from the phase segregation. The gels were characterized by X-ray powder diffraction, low temperature nitrogen adsorption, transmission and scanning electron microscopy (TEM, SEM and SEM/EDS), thermogravimetric analysis (TGA), and FT-IR spectra, to d...

It is now widely recognized that the phase composition, morphology and surface chemistry of the filler all exert a clear impact on the way it interacts with the polymer host, thus contributing to the final outcome in terms of ionic mobility, thermal, mechanical, chemical and electrochemical stability in lithium cells. In the present contribution we manufactured microporous polymer membranes based on copolymer poly(vinylidene fluoride-hexafluoropropylene) (PVdF/HFP) using a two-step approach originally proposed by Bellcore. A mesoporous silica filler MCM-41 was synthesized and functionalized with chlorosilane. After the effect of functionalization was verified by means of FTIR spectroscopy, the fillers were incorporated in the polymer matrices and the resulting dry c...

Determining the functional parameters of the studied filler was the main aim of this research. Thermal treatment leads to changes in its morphology and phase composition. A wide range of physicochemical techniques was used, such as low-temperature nitrogen adsorption, FT-IR, TGA, XRD, optical, and electron microscopy. The susceptibility of the material to micronisation was also tested (ball milling). Due to its widespread occurrence, opoka can be an attractive alternative to fillers such as silica or chalk. In order to verify this statement, polypropylene composites thereof were prepared by melt blending and injection molding, and studied by mechanical testing and microscopic imaging.

The practical context of the presented concept relates to the use of cracking reaction products as valuable chemical raw materials. The proposed analytical tools allow for quick assessment of reaction products, indication of the molecular weight range, or the presence of specific functional groups. We want to emphasize that vegetable oils can not only be raw products for biofuels but also an alternative to petrochemicals. The study was undertaken to determine the influence of acid-base properties of catalysts on the rapeseed oil conversion process at 500 C. The effect of these properties on the character of the process and quality of the products obtained was shown to be very high. Basic correlations between the formation of coke, gaseous products and dehydrogenation products, and acid-base parameters of the individual catalysts have been observed. The use of spectroscopic methods (FTIR-Fourier Transform Infrared Spectroscopy, 1 H NMR-Nuclear Magnetic Resonance) for fast qualitative analysis of the products is described.
