The efficient conversion of carbon dioxide into high-value chemicals presents a promising strategy for achieving neutrality. Defects play critical role in numerous catalytic reactions. However, an excessive number defects can lead to electron trapping, deactivating the catalyst surface. Optimizing defect concentration is crucial significantly enhancing performance. In this work, two types flower-like BN-based photocatalysts composed nanofibers were synthesized by situ self-assembly and high-temperature calcination. photocatalyst with fewer (Vpoor-BNF) achieved CO2 reduction rate 2 times higher than that more (Vrich-BNF), CO yield 32 μmol g–1 h–1 86.9% selectivity. Importantly, mechanism enhanced activity over BN-like was investigated combination various advanced characterization. results show C doping causes deposition, creating trap photogenerated electrons affect photocatalytic activity. contrast, Vpoor-BNF has longer carrier lifetime better photoelectric properties, which are beneficial photoreduction reaction. addition, good stability confirmed cyclic experiment. This study effective approach synthesizing defect-controlled catalysts, development photocatalysts.

Abstract Atomically precise copper(I) nanoclusters with stable active sites are highly sought‐after catalysts for the electrocatalytic CO₂ reduction reaction (CO₂RR), providing an exceptional platform to elucidate structure–activity relationships. However, rational synthesis of robust copper as effective electrocatalysts and understanding relationship between a more realistic site its performance remain significant challenge due their inherent instability. Here, novel dipropyne‐modified NHC ligand is elaborately devised two atomically nanoclusters, [Cu 17 H 6 (NHC ) 4 (dppm) ] 3+ ( Cu17a Ph Cu17b ), both exhibiting distinct unique square orthobicupola Cu core J 28 , Johnson solid). The σ‐ π‐bonding ligands imparts ultrahigh stability while coordination pattern μ 7 ‐ η σ 1 : π 2 facilitates exposure neighboring atoms, generating accessible catalytic sites. Electrocatalytic CO experiments show that achieves highest Faradaic efficiency ethylene production among reported nanoclusters. tandem mechanism RR elucidated through combination theoretical calculations attenuated total reflection‐surface‐enhanced IR absorption spectroscopy (ATR‐SEIRAS). This work not only introduces synthesizing but also offers critical insights into molecular design principles catalysts.
