18 maj 2021 · These results indicate Co/NC–N has a much better electrocatalytic ORR performance than Co(OH) 2 /NC, NC, NC–N and Co/NC–N–N, where the secondary-N-doping strategy and the synergistic effect of Co(OH) 2 supported on N-doped carbon are responsible for this enhanced performance.
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).
23 cze 2023 · According to Le Chatelier's principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. This particular reaction shows a total of 4 mol of gas as reactants and 2 mol of gas as products, so the reaction shifts toward the products side.
11 paź 2024 · The ECR performances of the Cu and Cu(OH) 2 NA catalysts were measured in a CO 2-saturated 1 M KHCO 3 (99.95%, Sigma-Aldrich, pH 8.6) and 1 M KOH (pH 13.7) electrolyte by chronopotentiometry measurements at a constant-current density of −300 and −150 mA cm −2, respectively.
17 mar 2022 · An electrochemical microkinetic model (exemplified on Cu (100)) is presented to adequately rationalize the experimental trends in C 2 Oxy/HC selectivity, revealing its dramatic dependency on...
If the products and reactants are in their standard states and ΔGo <0, then Kp> 1, and products are favored over reactants when the reaction is at equilibrium. Conversely, if ΔGo> 0, then Kp <1, and reactants are favored over products when the reaction is at equilibrium.
Here, we rationally designed Co(OH) 2 @CoSe nanorods (NRs) as an excellent bifunctional electrocatalyst by an in situ electrochemical transformation strategy, where the Co-based nanorod template was converted into Co(OH) 2 @CoSe at the cathode.
