Harnessing the hydrogen evolution reaction (HER) through the electrical mobility of an embossed Ag(i)-molecular cage and a Cu(ii)-coordination polymer

Abstract

Structurally characterized porous Ag(I)-molecular cage, AgMOC and Cu(II)-coordination polymer, CuCP with a premeditated ligand, 1,3-bis(((E)-2-methoxybenzylidene)amino)propan-2-ol and its parental amine with thiocyanate, respectively are reported to harness electrical mobility-driven hydrogen evolution...

AIE active fluorescent organic nanoparticles based optical detection of Cu2+ ions in pure water: a case of aggregation–disaggregation reversibility

“…8b, ESI†) indicating the existence of bivalent copper with a spin of . 77,78 Furthermore, FE-SEM images of the copper complex were recorded to assess the loss of the aggregated-nature of the FONs (Fig. 9).…”

Enhancing Electrochemical Hydrogen Evolution Performance of N-Heterocyclic Carbene-Coordinated Palladium(II) Complexes with Conductive Carbon: Insights from Hydrogen Oxidation Reactions

“…Among others, composite 7C displayed the lowest Tafel slope value, which signifies that it has exceptionally good chemical kinetics among the series for electrocatalytic reaction. The HER activities of these molecular electrocatalysts and their carbon composites are on par with other similar reports such as dithiophosphonate-anchored heterometallic (Ag­(I)/Fe­(II)) complexes, coordination polymer based on copper­(II) benzenehexathiol, Ag­(I)-molecular cage, Cu­(II)-coordination polymer, bimetallic cage-based metal–organic frameworks, metal NHCs supported on multiwalled carbon nanotubes, carbene-ligated Cu 3– x P nanocrystals, and other molecular electrocatalysts …”

Electrocatalytic hydrogen production activity with a copper(ii)-dipyridylamine complex in acidic water

“…To proceed with the electrocatalytic studies with the Cu(II) complex for the hydrogen evolution reaction (HER), acetic acid was employed as a proton source in water. 27,[63][64][65] Upon sequential addition of AcOH to the aqueous solution of [Cu(dpa) 2 (N 3 )] + a unidirectional elevation of a catalytic wave at −1.2 V {Fig. 3(c)} was observed, which is a definite signature for the electrocatalytic proton reduction to molecular hydrogen in water.…”
