10 sie 2021 · OER performance of Co(OH) 2 @NC was studied by linear sweep voltammogram (LSV) tests in 1 M KOH solution. Co(OH) 2 @NC shows a potential of 1.56 V at 10 mA cm −2 (Fig. 3 (a)), compared with 1.65 V for ZIF-NC and 1.64 V for IrO 2 at 10 mA cm −2. The overpotential value of Co(OH) 2 @NC also surpasses other reported Co-based OER ...
18 maj 2021 · In this work, a secondary-N-doping strategy is developed for enhancing the ORR electrocatalytic performance of Co (OH) 2 /NC, where NC is prepared from pyrolysis of carbon with melamine at 900 °C, then Co (OH) 2 /NC is obtained from depositing Co (OH) 2 nanosheets on NC.
Use a balanced chemical equation to determine molar relationships between substances. The previous section described the molar interpretation of a balanced chemical equation. The balanced chemical equation: N 2 (g) + 3 H 2 (g) → 2 NH 3 (g) tells us that 1 mol N 2 reacts with 3 mol H 2 to yield 2 mol NH 3.
How To Find Mole Ratio? Calculating mole ratios helps to estimate the theoretical yield of a chemical reaction. To calculate it, follow the steps below: Balance the chemical equation. Separate the coefficients of reactants and products.
