Phys.org  June 2, 2023 Researchers in Japan have fabricated the next-generation membrane electrodes for fundamental electrochemical research of amorphous-based porous carbon materials by the uniform carbon coating of anodic aluminum oxide formed on an Al substrate and free from a barrier layer. The conformally carbon-coated layer formed vertically aligned giant carbon nanotubes, and their walls comprised low-crystalline stacked graphene sheets. The diameter and the length of the nanopores could be tuned over a broad range of between 10 to 200 nm and 2 to 90 µm, respectively. Unlike composite electrodes made from other ordered nanoporous carbons, this model electrode exhibited […]
