Articles, systems, and methods for electrochemically generating chemical products

Abstract

Some aspects of the present disclosure are generally directed to systems for electrochemically generating compounds, for example, for generating hydrogen peroxide or other applications. In some cases, the systems may include electrodes containing a substrate comprising non-woven fibers comprising carbon, PTFE particles on the substrate, and / or an active material, for example, carbon particles, on the substrate and / or the PTFE. In some embodiments, the systems may generate and / or flow a two-phase solution over and / or through at least a portion of an electrode. Some systems using the electrode structures and / or two-phase solution may promote the formation of three-phase boundaries, and thus may facilitate the electrocatalytic generation of certain compounds at the three-phase boundaries. Still other aspects are directed to methods of making and / or using the systems, or the like.
