Abstract In this study, 2D multimetallic MOFs combined with the advantages of nanosheets, synergetic effect nodes, exhibited good photocatalytic activity for reduction CO 2 . Herein, a MOF‐Co/Cu/Fe were successfully prepared via one‐pot stirring solutions multimetal salts and organic ligands at room temperature. Introduction second third metal (Cu Fe) into MOF‐Co does not change morphology MOFs, although it improved performance by broadening light absorption range MOF‐Co, accelerating separation efficiency transfer rate photogenerated carriers. Upon irradiation full‐spectrum light, average yield achieved 17.06 µmol·g −1 ·h , being about 1.8 1.2 times that MOF‐Co/Cu. This work provides an insight MOFs‐based photocatalysts in catalytic reduction.

Amorphous catalysts possess substantially better catalytic activity toward water splitting than their crystalline counterparts. However, researchers have thus far focused on the rather amorphous phase due to complexity of synthesis and characterization. Here, crystalline-to-amorphous transformation charge redistribution induced by Fe F double substitution 3D Ni(OH)2 ultrathin nanosheet arrays are reported as a highly active stable bifunctional electrocatalyst for urea-assisted electrolysis. It is unveiled that synergistic effect dopant incorporation not only alters electronic configuration improved intrinsic but also creates abundant sites rich in Ni3+, which responsible significantly accelerated reaction kinetics. First, our findings show collected F–Fe–Ni(OH)2 catalyst exhibits excellent urea oxidation (UOR) with an overpotential 1.42 V generate 250 mA cm–2. Then, as-prepared can play dual role whole cell test, presenting voltage 1.68 V, 140 mV lower overall water-splitting system at 200 This work contributes novel approach synthesizing Ni-based materials electrocatalysts enhancement activities UOR hydrogen evolution reaction.
