Tube-in-tube hollow RuCrMn oxide nanofibers for noble-metal-efficient oxygen evolution via Cr/Mn-regulated Ru active sites
Reducing the Ru content while maintaining high oxygen evolution reaction (OER) activity remains a major challenge. In this study, single phase Ru0.30Cr0.31Mn0.39O2 nanofibers were prepared through electrospinning process followed by temperature-regulated heat treatment. The temperature regulation process induces a uniq...
