Nesbitt, N.T. (author), Smith, W.A. (author)Electrochemical atomic force microscopy (EC-AFM) enables measurement of electrode topography and mechanical properties during electrochemical reactions. However, for aqueous-based reactions that make gas products, such as CO2 reduction and water splitting into CO/H2, current densities below 1 mA cm-2 have been necessary to prevent formation...journal article 2021

Nesbitt, Nathan T. (author), Burdyny, T.E. (author), Salvatore, Danielle (author), Bohra, D. (author), Kas, Recep (author), Smith, W.A. (author)Electrochemical CO2 electrolysis to produce hydrocarbon fuels or material feedstocks offers a renewable alternative to fossilized carbon sources. Gas-diffusion electrodes (GDEs), composed of solid electrocatalysts on porous supports positioned near the interface of a conducting electrolyte and CO2 gas, have been able to demonstrate the...journal article 2020

Blommaert, M.A. (author), sharifian, rezvan (author), Shah, N. (author), Nesbitt, N.T. (author), Smith, W.A. (author), Vermaas, D.A. (author)A bipolar membrane (BPM), consisting of a cation and an anion exchange layer (CEL and AEL), can be used in an electrochemical cell in two orientations: reverse bias and forward bias. A reverse bias is traditionally used to facilitate water dissociation and control the pH at either side. A forward bias has been proposed for several...journal article 2021
