Adiabatic versus non-adiabatic electron transfer at 2D electrode materials

Abstract: Abstract2D electrode materials are often deployed on conductive supports for electrochemistry and there is a great need to understand fundamental electrochemical processes in this electrode configuration. Here, an integrated experimental-theoretical approach is used to resolve the key electronic interactions in outer-sphere electron transfer (OS-ET), a cornerstone elementary electrochemical reaction, at graphene as-grown on a copper electrode. Using scanning electrochemical cell microscopy, and co-located stru… Show more

“…To the best of our knowledge, our work is the first to report mapping of defects with enhanced kinetics with high spatial resolution coupled to analysis/modeling of their size and shape based on diffusion-limited currents. Our approach is complementary but highly novel with respect to prior reports by other groups such as Unwin and co-workers, , and Payne and Mauzeroll . The small contact area (approx.…”

“…Electrochemical scanning probe microscopy techniques typically demand complementary microscopy maps such as atomic force microscopy, electron microscopy, or optical microscopy to correlate the morphological features on surfaces with the electrochemical response. This approach was applied to 2D materials in our previous work , and other studies of 2D materials. It is somewhat limiting to correlate electrochemical response with complementary microscopy maps as it restricts the assignments to features that only require relatively large spatial resolution to be identified. Atomic-size features still require the use of techniques such as TEM or STM that are challenging to interface with electrochemical methods .…”

“…Mechanistic studies for the large reaction networks involved in eCO 2 R couple well with multiscale methods like MicroKinetic Modeling (MKM), as this technique can help delineate which reaction pathways have the dominant rates for selective production of the target hydrocarbon or alcohol products. Even though microkinetic modeling is vastly used in heterogeneous catalysis, its application to electrocatalysis is limited by the complexity embedded in the estimation of electrochemical activation barriers and potential contributions from electric field and solvent. Nevertheless, in the past few years, the use of microkinetic modeling has picked up pace and several studies have used MKM to simulate polarization curves for selective CO conversion from CO 2 . ,, A few recent studies have also used MKM to understand the complex reaction network for the formation of C 1 and C 2 hydrocarbon and alcohol products (see for instance ref ), thus the review mainly focuses on these works which go beyond assessment of CO formation.…”

“…A huge number of attempts have been carried out to elucidate the principle governing properties of electrocatalysis in order to search and discover better materials, and this attempt is still going on worldwide. This issue is a long-standing question in science spanning from physics to chemistry, and advancing energy technology to achieve carbon neutrality is now considered one of the most important challenges of the 21st century. Although a wide spectrum of intensive research has been conducted for more than a century, we are far from understand the microscopic origin well enough to describe the activity and selectivity of electrocatalysts even for the simplest multiproton/multielectron transfer energy conversion process of the hydrogen evolution reaction (HER).…”
