Assembling Metal Organic Layer Composites for High-Performance Electrocatalytic CO₂ Reduction to Formate.

ABSTRACT: 2D metal-organic-framework (MOF) based composites have emerged as promising candidates for electrocatalysis due to their high structural flexibility and fully exposed active sites. Herein, a freestanding metal-organic layer (MOL) with a 2D kgd (kagome dual) lattice was constructed with abundant surface oxygenate groups serving as anchoring sites to immobilize diverse guests. Taking Bi as an example, tetragonal Bi₂ O₃ nanowires can be uniformly grown on MOLs after solvothermal treatment, the structural evolution of which was followed by ex situ electron microscopy. The as-prepared Bi₂ O₃ /MOL exhibits excellent CO₂ electroreduction activity towards formate reaching a specific current of 2.3 A mg_Bi ^-1 and Faradaic e
