Electrochemically Grown Ultrathin Platinum Nanosheet Electrodes with Ultralow Loadings for Energy-Saving and Industrial-Level Hydrogen Evolution
Autor: Lei Ding, Zhiqiang Xie, Shule Yu, Weitian Wang, Alexander Y. Terekhov, Brian K. Canfield, Christopher B. Capuano, Alex Keane, Kathy Ayers, David A. Cullen, Feng-Yuan Zhang
Publikováno v: Nano-Micro Letters, Vol 15, Iss 1, Pp 1-18 (2023)
Highlights 4-nm-thick Pt nanosheets (Pt-NSs) are electrochemically grown on Ti substrates for hydrogen evolution reactions. Highly uniform Pt-NS surface coverage with an ultralow loading of 0.015 mgPt cm−2 is achieved. 99.5% catalyst savings and ab

AEM Electrolysis Testing Update and Industrial Device Requirements
Autor: Christopher B Capuano, Kathy Ayers, Alex Keane
Publikováno v: ECS Meeting Abstracts. :1730-1730
Membrane (PEM)-based electrolysis provides an ideal near-term technology to address the growing energy storage demands as intermittent renewable energy becomes more prevalent. While proton exchange membrane (PEM) systems are often viewed as preferred

Development of Membrane Electrode Assemblies for State-of-the-Art Anion Exchange and Proton Exchange Membrane Electrolysis
Autor: Andrew R Motz, Christopher B Capuano, Katherine E. Ayers
Publikováno v: ECS Meeting Abstracts. :1727-1727
Proton exchange membrane (PEM) electrolysis and anion exchange membrane (AEM) electrolysis are both able to directly produce high purity hydrogen from electricity and water. Key benefits of electrolysis using polymer membrane separators include a qui
