which is not high enough for use as electrolyte for NAT-SOFCs22. In order to improve the ionic conductivity at low temperatures, it is necessary to increase the concentration of charge carriers, i.e., the proton defects. Therefore, we ...
42. The surface energy (α) was determined by using the following equation: $${\alpha }=\frac{{E}_{slab}-{n}{E}_{bulk}}{2{A}}$$ (1) where\({E}_{{slab}}\)is the total energy of the slab,\({E}_{{bulk}}\)is the energy of a bulk unit,nis the number of bulk unit ...
electrolysis. In specially designed water electrolyzer systems, water electrolysis is usually carried out via two reaction paths, such as oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). OER is the more difficult of the two half-reactions, as it is a four-electron transfer ...
In two-chamber microbial electrolysis cells (MECs) with anion exchange membranes (AEMs), a phosphate buffer solution (PBS) is typically used to avoid increases in catholyte pH as Nernst equation calculations indicate that high pHs adversely impact electrochemical performance. However, ion transport ...
To tabulate the conversion with respect to manipulated variables, the required equation (Equations (14) and (15)) was introduced as a Fortran statement. Then, the simulation model was executed for different manipulated variables. Based on these resulting conversion values, the number of graphs was...

After 15 min, 10 mL 5 mM NaOH was slowly dropped into the above solution and stirring was allowed to last for half an hour. Finally, the transparent colloid solution of Ni(OH)2 was obtained with no precipitation happened. 2.3. Electrodeposition of Ni(OH) /NiOOH catalyst and electrochemical...
(E) were converted to the reversible hydrogen electrode (RHE) based on the following equation: ERHE = EHg/HgO + 0.059 pH + E0Hg/HgO. The potential of reference electrode and the pH value of the used electrolyte were examined before the electrochemical measurement (...
V according to the equation Eg = 1240 λ . The light absorption threshold of the CoPi/Co(OH)2 surface-modified Ta3N5 is wider than the unmodified one, hence the narrowed band gap would result in lower photogenerated electron transition energy, stronger photocatalytic activity, and better ...
