Tīmeklis2024. gada 20. janv. · Weak binding and affinity between the conductive support and iodine species leads to inadequate electron transfer and the shuttle effect. Herein, redox kinetics and duration are significantly boosted by introducing a Nb 2 CT X host that is classified as a layered 2D Nb-based MXene. With a facile electrodeposition strategy, … Tīmeklis2024. gada 7. apr. · Step 1: Separate the half-reactions that undergo oxidation and reduction. Oxidation: I − I 2 This is the oxidation half because the oxidation state changes from -1 on the left side to 0 on the right side. This indicates a gain in electrons. Reduction: MnO − 4 Mn2 +
