Amaranthus waste is reported to be a single precursor synthesize highly porous nitrogen-doped carbon as superior oxygen reduction electrocatalyst.
Surface and interface engineering, especially the creation of abundant Cu0/Cu+ interfaces nanograin boundaries, is known to facilitate C2+ production during electrochemical CO2 reductions over copper-based catalysts. However, precisely controlling favorable boundaries with surface structures (e.g., Cu(100) facets Cu[n(100)×(110)] step sites) simultaneously stabilizing challenging, since Cu+ species are highly susceptible be reduced into bulk metallic Cu at high current densities. Thus, an...
Challenges in CO2 capture, crossover, product separation, and electrolyte recovery hinder electrocatalytic reduction (CO2R). Here, we present an integrated electrochemical separation system (ERSS) with ion module (ISM) between the anode cathode of a water electrolysis system. During ERSS operation, protons from anolyte flow through anodic cation exchange membrane (CEM) into ISM, acidifying CO2R effluent electrolyte. Cations like K+ ISM cathodic CEM catholyte to balance OH- ions hydrogen...
Electrocatalytic CO2 reduction reaction (CO2 RR) offers a promising strategy to lower emission while producing value-added chemicals. A great challenge facing RR is how improve energy efficiency by reducing overpotentials.

Metal-organic frameworks (MOFs) can be utilized as electrocatalysts for CO2 reduction reaction (CO2RR) due to their well dispersed metal centers. However, the influence of node distribution on electrochemical CO2RR was rarely explored. Here, three Cu-MOFs with different copper(II) site were employed electroreduction.
