Restructuring multi-phase interfaces from Cu-based metal-organic frameworks for selective electroreduction of CO to CH.

Multi-phase interfaces are promising for surmounting the energy barriers of electrochemical CO reduction involving multiple electron transfer steps, but challenges still remain in constructing interfacial micro-structures and unraveling their dynamic changes and working mechanism. Herein, highly active Ag/Cu/CuO heterostructures are electrochemically restructured from Ag-incorporating HKUST-1, a Cu-based metal-organic framework (MOF), and accomplish efficient CO-to-CH conversion with a high faradaic efficiency (57.2% at -1.

Redox regulation of Ni hydroxides with controllable phase composition towards biomass-derived polyol electro-refinery.

Electrocatalytic refinery from biomass-derived glycerol (GLY) to formic acid (FA), one of the most promising candidates for green H carriers, has driven widespread attention for its sustainability. Herein, we fabricated a series of monolithic Ni hydroxide-based electrocatalysts by a facile and electrochemical method through the manipulation of local pH near the electrode. The as-synthesized Ni(OH)@NF-1.
