The growing climate crisis inspires one of the greatest challenges of the 21st century—developing novel power sources. One of the concepts that offer clean, non-fossil electricity production is fuel cells, especially when the role of fuel is played by simple organic molecules, such as low molecular weight alcohols. The greatest drawback of this technology is the lack of electrocatalytic materials that would enhance reaction kinetics and good stability under process conditions. Currently, electrodes for direct alcohol fuel cells (DAFCs) are mainly based on platinum, which not only provides a poor reaction rate but also readily deactivates because of poisoning by reaction products. Because of these disadvantages, many researchers have focused on developing novel electrode materials with electrocatalytic properties towards the oxidation of simple alcohols, such as methanol, ethanol, ethylene glycol or propanol. This paper presents the development of electrode materials and addresses future challenges that still need to be overcome before direct alcohol fuel cells can be commercialized.

“…The electrodeposition process is one of the methods for manufacturing thin solid layers from an electrolyte solution using electric field. It has found application in various industries such as biology, biotechnology, biochemistry, chemistry, materials science and waste-water treatment [ 1 , 2 , 3 ]. Originally, the electrodeposition process was used for obtaining metal coatings.…”

Investigation of Parameters Influencing Tubular-Shaped Chitosan-Hydroxyapatite Layer Electrodeposition

2020

View full text Add to dashboard Cite

Tubular-shaped layer electrodeposition from chitosan-hydroxyapatite colloidal solutions has found application in the field of regeneration or replacement of cylindrical tissues and organs, especially peripheral nerve tissue regeneration. Nevertheless, the quantitative and qualitative characterisation of this phenomenon has not been described. In this work, the colloidal systems are subjected to the action of an electric current initiated at different voltages. Parameters of the electrodeposition process (i.e., total charge exchanged, gas volume, and deposit thickness) are monitored over time. Deposit structures are investigated by scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). The value of voltage influences structural characteristics but not thickness of deposit for the process lasting at least 20 min. The calculated number of exchanged electrons for studied conditions suggests that the mechanism of deposit formation is governed not only by water electrolysis but also interactions between formed hydroxide ions and calcium ions coordinated by chitosan chains.

“…The growing interest of using nano-sized metal oxide as adsorbent in dye adsorption is attributed to its simple synthesis process, cheapness, high surface area and nontoxicity [13,[16][17][18][19]. However, few studies have emphasized the advantages of aluminum oxide (alumina) nanoparticles for reactive dye adsorption.…”

Removal of reactive yellow 160 from aqueous solution by alumina nanoparticles derived from aluminium waste residue

I N the current study, alumina nano particles were prepared from waste aluminum residue by an extraction and gel formation method. The prepared alumina nanoparticles were used to remove reactive yellow 160 (RY160) from an aqueous solution. The kinetics and adsorption equilibrium were discussed as well.The results show that, the heat-treated samples were consisting of Al and O elements only and their crystalline phase was pure alumina in the nano scale. The alumina nanoparticles were effective adsorbents for the removal of RY160 from aqueous solution with percentage removal 100 % for samples heat-treated at 110°C and 600°C. The adsorption data was well fitted to Langmuir isotherm model for all prepared samples indicating a monolayer adsorption. The adsorption process was found to be endothermic and the adsorption takes place physically on the surface of alumina nanoparticles. The prepared alumina nanoparticles samples can be used as an efficient adsorbent in water treatment.
