In a comparative study of the electrocatalytic CO2 reduction, cobalt meso-tetraphenylporphyrin (CoTPP) is used as model molecular catalyst under both homogeneous and heterogeneous conditions. former case, employing N,N-dimethylformamide solvent, CoTPP performs poorly an electrocatalyst giving low product selectivity in slow reaction at high overpotential. However, upon straightforward immobilization onto carbon nanotubes, remarkable enhancement abilities seen with becoming selectively...
Earth-abundant transition metal (Fe, Co, or Ni) and nitrogen-doped porous carbon electrocatalysts (M-N-C, where M denotes the metal) were synthesized from cheap precursors via silica-templated pyrolysis. The effect of material composition structure (i.e., porosity, nitrogen doping, identity, oxygen functionalization) on activity for electrochemical CO2 reduction reaction (CO2RR) was investigated. metal-free N-C exhibits a high selectivity but low CO2RR. Incorporation Fe Ni, not sites in is...
Cu is in the spotlight as it represents only metal capable of catalyzing CO2 reduction to multicarbon products. However, its catalytic performance determined collectively by a number parameters including composition and structure, electrolyte, cell configuration.

In this work, we study electrode–electrolyte interface on water coating CuO electrodes with polymers varying hydrophilicities/phobicities. Hydrophilic...
Abstract A nitrogen‐stabilized single‐atom catalyst containing low‐valence zinc atoms (Zn δ+ ‐NC) is reported. It contains saturated four‐coordinate (Zn‐N 4 ) and unsaturated three‐coordinate 3 sites.

Abstract Recently, a large number of nanostructured metal‐containing materials have been developed for the electrochemical CO 2 reduction reaction (eCO RR). However, it remains challenge to achieve high activity and selectivity with respect metal load due limited concentration surface atoms.

Electrochemical CO2 reduction represents a promising path toward the production of value-added chemicals. Atomically dispersed metal sites on nitrogen-doped carbon have demonstrated outstanding catalytic performance in this reaction. However, challenges remain developing such catalysts beyond transition metals. Herein, we present two types p-block indium single-atom catalysts: one with four nitrogen coordinated (In–N4) and another three vacancy nearby (In–N3–V). In electrochemical reduction,...
