Au on highly hydrophobic carbon substrate for improved selective CO production from CO2 in gas-phase electrolytic cell

Formation of 1-Butanol from CO2 without *CO Dimerization on a Phosphorus-Rich Copper Cathode

“…13 Herein, we propose a reaction pathway excluding *CO dimerization for the production of 1-butanol from CO 2 with a higher faradaic efficiency, using copper phosphide (CuP 2 ) gas diffusion electrodes in a continuous gasphase CO 2 electrolyzer. 19 The results are confirmed by in situ surface analysis and by analyzing some of the intensive products and intermediates.…”

The role of electrode wettability in electrochemical reduction of carbon dioxide

“…74,133 Instead, this enhancement over GDE can be considered to be a result of (1) the shortened CO2 diffusion distances in the liquid film from 40 -160 μm 134,135 to 0.01 -20 μm 42, 136 and (2) an increased density of active sites per geometric electrode area. Again, note that the relatively thick hydrodynamic layers (0.01 -20 μm) at the catalyst surface makes the CL pores (typically less than a few hundred nanometers in size) [137][138][139][140] hardly maintain a wet pore condition (i.e., the pore surface is wet while gas still transports through, as depicted in Figure 7c) as proposed by…”

Precursor film formation on catalyst–electrolyte–gas boundaries during CO2 electroreduction with gas diffusion electrodes

“…67 Many experimental studies have reported the use of GDE in electrocatalytic systems and indicated the success of the presence of TPB formation during CO 2 electroreduction. 9,[14][15][16][17]21,[68][69][70][71][72][73][74][75][76][77][78] Mostly Cu-based electrocatalysts were used in these studies. Faradaic efficiency values of 71.3% have been achieved for the CO 2 reduction to gaseous hydrocarbons at current densities >500 mA cm −2 using a GDE with a CL containing PTFE, Cu, and carbon black, enabling a stable TPB of CO 2 / catalyst/aqueous electrolyte in 1990.…”
