Abstract Nature enzymes always suffer from high costs, harsh conditions, and instability, while, artificial one offers possibilities for addressing current challenges plays a significant role in future industrial production. Here, the carbon dots (CDs), with well‐defined polycyclic dipeptide structures, are reported to exhibit superior hydrolase‐like catalytic performance beyond those of natural enzymes. Compared lipase, obtained CDs not only activity (2.85 times increase V m ) but also have broader range substrate concentrations (0–8.0 types (fatty ester, aromatic phosphate ester), along simpler conditions stability. The highly efficient is attributed low activation energy reaction (E : 13.74 kJ mol −1 strong adsorption substrates. results theoretical calculations comparative experiments demonstrate that sites located on nitrogen atoms dipeptide. Furthermore, membrane integrated (membrane‐catalyst) constructed, through which instantaneous hydrolysis esters can be realized. This work provides new insight into enzyme‐like mechanisms approach designing materials performance.
