Figure 5. (A) Scheme illustration of the assembly process of [V₁₀O₂₈]^6-, Na⁺ and TRIS⁺ to form 1@CNT. (B) HRTEM image of 1@CNT acquired at 200 kV. (C) Linear sweep voltammetry (LSV) curves of 1/CNT (red), 1@CNT (blue), CNT (black), and commercial Pt/C benchmark catalyst for the HER. (D) Comparison of the OER catalytic performance of 1/CNT (red) and bare CNT (black), with Ir/C (black dashed line) and IrO₂/C as reference electrocatalysts. (E) Proposed mechanism for EWS over compound 1, involving an OER process coupled with the AOR. (A-E) Reproduced with permission from^[86]. Copyright 2025, Wiley-VCH GmbH.
