WebPolymerization can be defined as the process of producing polymers in simple terms. Polymerization is a chemical event in which smaller molecules known as monomers are united to generate larger molecules. A polymer consists of a cluster of these big molecules. In general, the term polymer refers to "big molecules" with a larger molecular mass. WebHere, a coordination polymer (CP) catalyst is reported that consists of Cu(I) and benzimidazole units linked via Cu(I)-imidazole coordination bonds, which enables selective reduction of CO to acetate with a 61% Faradaic efficiency at −0.59 volts versus the reversible hydrogen electrode at a current density of 400 mA cm−2 in flow cells.
