10 sie 2021 · Co(OH) 2 @NC cathode delivers a maximal discharging current density nearly 300 mA cm −2 while Pt/C-IrO 2 only reaches 200 mA cm −2 at 0.5 V. The peak power density of Co(OH) 2 @NC (Fig. 5 (c)) is about 148 mW cm −2, significantly larger than the value of Pt/C-IrO 2 (106 mW cm −2).
13 lut 2023 · Learning Objectives. To use graphs to analyze the kinetics of a reaction. You learned that the integrated rate law for each common type of reaction (zeroth, first, or second order in a single reactant) can be plotted as a straight line.
5 lis 2021 · The present work proposes a new set of Pitzer interaction parameters through the set of CO 2 solubility data in saline systems such as CO 2-H 2 O-NaCl and CO 2-H 2 O-Na 2 SO 4. The determined model is capable of covering a wide T − P − I range (273.15–473.15 K, 0.1–40 MPa and 0–6 mol/kg).
29 paź 2024 · During the electrochemical CO2 reduction reaction (eCO2RR) on copper catalysts, linear-bonded CO (*COL) is commonly regarded as the key intermediate for the CO-CO coupling step, which leads to the formation of multicarbon products. In this work, we unveil the significant role of bridge-bonded *CO (*COB) as an active species. By combining in situ Raman spectroscopy, gas and liquid ...
23 paź 2021 · Abstract. The electrochemical CO 2 reduction reaction (ECO 2 RR) on Cu catalysts affords high-value-added products and is therefore of great practical significance. The outcome and kinetics of ECO 2 RR remain insufficient, requiring essentially the optimized structure design for the employed Cu catalyst, and also the fine synthesis controls.
15 maj 2013 · Under your definition of favourability by addition, you're weighing reagents and products unfairly, in some sense, because in the expression of $K_c$ there are two reagents and one product.
27 paź 2022 · Derive reaction quotients from chemical equations representing homogeneous and heterogeneous reactions. Calculate values of reaction quotients and equilibrium constants, using concentrations and pressures. Relate the magnitude of an equilibrium constant to properties of the chemical system.
