Mol. electrocatalysts show promise for energy-relevant multielectron transformations due to their rationally tunable activity and selectivity from systematic ligand modifications. However, surface-immobilized mol. electrocatalytic systems are typically limited by low activity per geometric surface area compared to traditional solid-state analogs because of their lower active site surface coverage. Many existing methods for increasing surface coverage through the formation of multilayer films are based on radical-coupling or electropolymerization strategies that often result in dense, poorly defined films that may inhibit charge or substrate transport and complicate mechanistic studies. The authors report an alternative controlled layer-by-layer deposition strategy for the formation of multilayer catalyst films on C electrode surfaces based on sequential Cu(I)-catalyzed azide-alkyne cycloaddition reactions. As a proof of concept, the authors explore the growth of multilayer films of Cu(3,8-diethynylphenanthroline) for the O reduction reaction. Double-layer catalyst films operate with increased activity and selectivity for the reduction of O2 to H2O compared to single-layer catalyst films. The authors attribute this increased activity and selectivity to the increased coverage of the double-layer films which both increases the number of active sites and facilitates the 4e- reduction to H2O, rather than the 2e- reduction to H2O2. Unfortunately, growth of triple-layer catalyst films in this system was unsuccessful, possibly due to steric congestion in the double-layer films. The experimental process involved the reaction of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8HPLC of Formula: 510758-28-8)
Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8) can stabilizes Cu(I) towards disproportionation and oxidation thus enhancing its catalytic effect in the azide-acetylene cycloaddition.HPLC of Formula: 510758-28-8Polytriazolylamines were synthesized by the copper(I)-catalyzed ligation of azides and alkynes.
