Abstract Single‐atom nanozymes exhibit unique enzymatic activity due to their active centers, which resemble those of natural metalloenzymes. The design the anchoring sites single‐atom centers is an important factor that affects loading capacity and catalytic activity. Herein, para‐nitrogen‐doped graphyne with diamond cavity used as support, tellurium atoms are then anchored in nitrogen‐containing cavities, akin chess pieces placed on a chessboard grid. Due pre‐designed regular sites, site‐defined nanozyme (Te SAN) achieves high Te 19.21 wt.%. Therefore, SAN shows good peroxidase‐like To explain enhanced activity, density functional theory calculations performed results demonstrate doping enhances by lower Gibbs free energy barrier for formation •OH, key intermediate Finally, based inhibitory effect bisphenols SAN‐based sensor array successfully identifies five bisphenols, holding potential on‐site food safety monitoring. single this work provides new ideas precisely controlling synthesis nanozymes, exploring action mechanisms, enhancing activities.
