The charge of the electrodes was balanced using equation (8). This balancing results in the mass difference between the positive electrode and the negative electrode of 1 to 7.1. CV of the cell, Fig. 6a, display redox peaks in the extended working voltage of 1.9 V due to the ...
Calculate for the delta Hrxn for the reaction CH4(g) + 2O2(g) -> CO2(g) + 2H2O(l) if the delta Hf of CH4(g) = 74.8kJ; CO2(g) = 393.5kJ; H2O(l) = 285.8kJ. Calculate the standard molar enthalpy of reaction Delta H_{rxn}^{cir...
If there is really a double bond in phosphine oxides this bond is closer to that in o2 (qith two half 11-bonds) than .to that in ethylene. (A better and simpler model for the bonding situation in phosphine oxide may be BF, where there is a single B-Fo bond and back-bonding from ...
The COVID-19 pandemic has seen a considerable expansion in the way work settings are structured, with a continuum emerging between working fully in-person and from home. The pandemic has also exacerbated many risk factors for poor mental health in the wo
The selectivity towards CO2 was calculated by (Equation (6)): selCO2 (%) = 1 λ XCO XO2 × 100 (6) where XCO and XO2 are the CO and O2 conversions and λ is: λ=2 × niOn2 niCnO (7) The excess oxygen factor (λ) (Equation (2) used in this work was 2 considering th...

The reaction gas mixture consisted of 0.2 vol.% of CO and 1 vol.% O2 both balanced with He. A total feed stream of 80 cm3 min−1 was used, corresponding to a gas hourly space velocity (GHSV) of 40,000 h−1. Before catalytic tests, all samples were pretreated under 20 vol.% ...
Moreover, in co-electrolysis mode, a mixture of H2O and CO2 is converted directly into syngas (CO + H2). Depending on the process equilibrium, the (reverse) water gas shift reaction ((R)WGS) takes place on the fuel side (Equation (3)) [1]. H2O + 2e− → H2 + 1/2 O2− ...
(overall reaction: NO + 1/2O2 → NO2 and NO2 + soot → CO + CO2). Pt and dual Ni/Co cations in the Pt/Ni1.5Co0.5AlO catalysts achieved synergistic catalytic soot combustion. There- fore, the Ptn/Ni1.5Co0.5AlO catalysts exhibited excellent catalytic performance to boost soot combustion...
