To facilitate the electrochem. CO2 reduction (ECR) to fuels and valuable chems., the development of active, low cost, and selective catalysts is crucial. We report a novel ECR catalyst consisting of CuO nanoparticles with sizes ranging from 1.4 to 3.3 nm anchored on Cu metal-organic framework (Cu-MOF) nanosheets obtained through a one-step facile solvothermal method. The nanocomposites provide multiple sites for efficient ambient ECR, delivering an average C2H4 faradaic efficiency (FE) of ∼50.0% at -1.1 V (referred to the reversible hydrogen electrode) in 0.1 mol/L aqueous KHCO3 using a two-compartment cell, in stark contrast to a C2H4 FE of 25.5% and 37.6% over individual CuO and Cu-MOF resp., also surpassing most newly reported Cu-based materials under similar cathodic voltages. The C2H4 FE remains at over 45.0% even after 10.0 h of successive polarization. Also, a ∼7.0 mA cm-2 C2H4 partial geometric c.d. and 27.7% half-cell C2H4 power conversion efficiency are achieved. The good electrocatalytic performance can be attributed to the interface between CuO and Cu-MOF, with accessible metallic moieties and the unique two-dimensional structure of the Cu-MOF enhancing the adsorption and activation of CO2 mols. This finding offers a simple avenue to upgrading CO2 to value-added hydrocarbons by rational design of MOF-based composites. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Recommanded Product: Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents has turned up as an exceedingly robust synthetic tool. The copper-mediated C-C, C-O, C-N, and C-S bond formation is a part of one oldest reaction, emphasizing the Ullmann cross-coupling reaction.Recommanded Product: Cuprichydroxide
