《Hydroxide is not a Promoter of C2+ Product Formation in the Electrochemical Reduction of CO on Copper》 was written by Li, Jing; Wu, Donghuan; Malkani, Arnav S.; Chang, Xiaoxia; Cheng, Mu-Jeng; Xu, Bingjun; Lu, Qi. SDS of cas: 33100-27-5 And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:
Highly alk. electrolytes improve the formation rate of C2+ products in the electrochem. reduction of CO2 (CO2) and CO on Cu surfaces, with the assumption that higher OH- concentrations promote the C-C coupling chem. Herein, by systematically varying the concentration of Na+ and OH- at the same absolute electrode potential, higher concentrations of (Na+), rather than OH-, exert the main promotional effect on the production of C2+ products. The impact of the nature and the concentration of cations on the electrochem. reduction of CO is supported by experiments in which a fraction or all of Na+ is chelated by a crown ether. Chelation of Na+ leads to drastic decrease in the formation rate of C2+ products. The promotional effect of OH- determined at the same potential on the reversible H electrode scale is likely caused by larger overpotentials at higher electrolyte pH. In the experimental materials used by the author, we found 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5SDS of cas: 33100-27-5)
1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. SDS of cas: 33100-27-5
