Polymer coordination promotes selective CO2 reduction by cobalt phthalocyanine.
Cobalt phthalocyanine (CoPc) is a known electrocatalyst for the carbon dioxide reduction reaction (CO2RR) that, when adsorbed onto edge-plane graphite (EPG) electrodes, shows modest activity and selectivity for CO production along with co-generation of H2. In contrast, electrodes modified with CoPc immobilized in a poly-4-vinylpridine (P4VP) film show dramatically enhanced activity and selectiv...
متن کاملMECHANISM PATHWAY FOR THE ELECTROCATALYTIC REDUCTION OF CO2 BY [Mn(bipyridyl)(CO)3X] DERIVATIVE
For more than a century human activities have caused an increase in air pollutants inducing an excess of greenhouse gases. In addition, the depletion and rising costs of fossil fuels, due to the increase in energy demand driven by global growth, leads to the search for alternative raw carbon sources. In this particular context, the transformation and utilization of carbon dioxide is today under...
متن کاملHighly selective and active CO2 reduction electrocatalysts based on cobalt phthalocyanine/carbon nanotube hybrid structures
Electrochemical reduction of carbon dioxide with renewable energy is a sustainable way of producing carbon-neutral fuels. However, developing active, selective and stable electrocatalysts is challenging and entails material structure design and tailoring across a range of length scales. Here we report a cobalt-phthalocyanine-based high-performance carbon dioxide reduction electrocatalyst materi...
متن کاملElectrocatalytic reduction of CO2 to CO by polypyridyl ruthenium complexes.
Electrocatalytic reduction of CO(2) by [Ru(tpy)(bpy)(solvent)](2+) (tpy = 2,2':6',2''-terpyridine, bpy = 2,2'-bipyridine) and its structural analogs is initiated by sequential 1e(-) reductions at the tpy and bpy ligands followed by rate limiting CO(2) addition to give a metallocarboxylate intermediate. It undergoes further reduction and loss of CO.
متن کاملStudies of Cobalt-Mediated Electrocatalytic CO2 Reduction Using a Redox-Active Ligand
The cobalt complex [Co(III)N4H(Br)2](+) (N4H = 2,12-dimethyl-3,7,11,17-tetraazabicyclo-[11.3.1]-heptadeca-1(7),2,11,13,15-pentaene) was used for electrocatalytic CO2 reduction in wet MeCN with a glassy carbon working electrode. When water was employed as the proton source (10 M in MeCN), CO was produced (fCO= 45% ± 6.4) near the Co(I/0) redox couple for [Co(III)N4H(Br)2](+) (E1/2 = -1.88 V FeCp...
