A 2e⁻ ORR electrocatalyst, comprised of oxygen-coordinated Fe single atoms and atom clusters anchored onto bacterial cellulose-derived carbon, was successfully fabricated. This material exhibited superior electrocatalytic activity toward H₂O₂ production and allowed for coupling by an electro-Fenton process, primarily owing to the active sites of Fe atom clusters with optimized electronic structure regulated by Fe single atoms, resulting in the suitable binding strength of the *OOH intermediate.

原子分散铁调节铁原子团簇的电子结构用于电催化 H2O2 生产和生物质升级

成功制造了一种 2e ^- ORR 电催化剂，由锚定在细菌纤维素衍生碳上的氧配位 Fe 单原子和原子簇组成。该材料对H ₂ O ₂生产表现出优异的电催化活性，并允许通过电芬顿过程进行偶联，这主要是由于Fe原子簇的活性位点具有受Fe单原子调节的优化电子结构，从而产生了合适的结合强度*OOH 中间体。
