Influence of Reaction Parameters on Nanogold-Catalyzed Glucose and Xylose Oxidation: A Joint Experimental and DFT Study Open
The electrocatalytic oxidation (ECO) of glucose on gold requires alkaline conditions and relatively high potentials (>0.3 V-RHE). Although the adsorption of hydroxide ions (OHads) is also known to occur under these conditions, the generall…

Electrocatalytic Hydrogenation of Glucose and Xylose on Electrochemically Roughened Metal Catalysts Open
Electrocatalytic hydrogenation (ECH) of glucose and xylose was studied on Ag, Au, Cu, Pt, and Zn polycrystalline metals. The metal catalysts were roughened electrochemically to expose more active sites. Estimates of surface roughness obtai…

Solid Foam Ru/C Catalysts for Sugar Hydrogenation to Sugar Alcohols─Preparation, Characterization, Activity, and Selectivity Open
Sugar alcohols are obtained by hydrogenation of sugars in the presence of ruthenium catalysts. The research effort was focused on the development of solid foam catalysts based on ruthenium nanoparticles supported on active carbon. This cat…

Dependence of the potentiometric response of PEDOT(PSS) on the solubility product of silver salts Open
The potentiometric response of the conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(styrenesulfonate) (PSS) deposited on glassy carbon (GC), i.e. GC/PEDOT(PSS), was studied before and after conditioning in silver…
