Abstract Dual‐atom catalysts exhibit higher reactivity and selectivity than the single‐atom catalysts. The pyrolysis of bimetal salt precursors is most typical method for synthesizing dual‐atomic catalysts; however, finiteness salts limits variety In this study, a confined synthesis strategy developed. Owing to in situ zeolitic imidazolate frameworks pores covalent organic (COFs), migration aggregation metal atoms are suppressed adequately during process. resultant catalyst contains abundant Zn─Co dual atomic sites with 2.8 wt.% Zn 0.5 Co. exhibits high toward oxygen reduction reaction half‐wave potential 0.86 V, which superior that commercial Pt/C catalyst. Theoretical calculations reveal promote formation intermediate OOH*, thus contribute catalytic performance. This study provides new insights into design dual‐atom using COFs.

Taking advantage of the metal–support interaction is an efficient strategy to rationally design cost-effective and highly catalysts. Herein, we report that tiny Pt species anchored on nanoceria with N-rGO as support (denoted Pt-CeO2/N-rGO) display size-dependent activity toward hydrogen evolution reaction (HER). The PtSAPtNC-CeO2/N-rGO far more active than PtSA-CeO2/N-rGO PtSAPtNP-CeO2/N-rGO. overpotential at 10 mA/cm2 only 26 mV for (5.0 wt %), ∼16 119 lower commercial Pt/C (20.0 %) a catalyst supported similar dispersion form (11.0 respectively. DFT calculations reveal electron between CeO2 greatly favor water adsorption reduce H2 energy barrier, which was further optimized by synergistic effect PtSA PtNC. XPS measurement charge density difference analysis indicate electrons transfer from single atoms reversely donate nanoclusters. electron-rich nanoclusters enhance electronic conductivity catalysts thus accelerate kinetics. Our work provides idea how optimize catalytic performance via manipulating interaction.
