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.

Abstract In order to improve the solubility of metallated monomers and product crystallinity, metal–covalent organic frameworks (MCOFs) are commonly prepared via high‐temperature sol‐vothermal synthesis. However, it hampers direct extraction crystallization evolution information. Exploring facile room‐temperature strategies for both synthesizing MCOFs exploiting crystallinity mechanism is extremely desired. Herein, by a novel single‐phase synthetic strategy, three with different microstructure rapidly based on Schiff base reaction between planarity‐tunable C 3v at room temperature. Based detailed time‐dependent experiments theoretical calculations, found that there planarity‐tuned competitive growth relationship disordered structures crystal nucleus first time. The high planarity boosts formation rapid growth, suppressing forming amorphous structures. addition, microenvironment effect selective photocatalytic coupling benzylamine (BA) investigated. strong donor‐acceptor (D‐A) MCOF exhibits efficient activity conversion rate 99% selectivity in 5 h under 520 nm light irradiation. This work opens new pathway scalable synthesis highly crystalline MCOFs.
