Stable acidic H <sub>2</sub> O <sub>2</sub> electrosynthesis <i>via in situ</i> Ti–N bridging sites
Acidic hydrogen peroxide electrosynthesis suffers from catalyst instability issues. We develop the MIL-125@Ppy catalyst, achieving a high H<sub>2</sub>O<sub>2</sub> electrosynthesis yield rate of 69.5 mol g<sub>cat</sub><sup>-1</sup> h<sup>-1</sup> (faradaic efficiency of 82.2%) at pH = 1 for operation more than 50 h. Spectroscopic evidence confirms that <i>in situ</i>-formed Ti-N bridge sites mediate the stabilization of *OOH, enabling the selective and stable two-electron pathway.
