Electrosynthesis of Jahn–Teller Distorted CoIV=O Species for Efficient Oxidant-Free Water Purification and Resource Recovery
This study introduces a phosphorus-doped single-atom cobalt catalyst that utilizes Jahn–Teller distortion to stabilize high-valent CoIV=O species, enabling an efficient, oxidant-free electrochemical process for water purification and simultaneous nickel resource recovery.
