Solution plasma synthesis of birnessite-type MnO 2 /carbon composites: support-dependent surface chemistry and alkaline oxygen reduction performance

Year: 2026

Type: article

Abstract: at 0.464 V. CNT-M0.5 showed the highest onset potential within the CNT series, 0.804 V. CNT-M0.5 and KB-M1 retained 93.1% and 90.8% of their initial currents, respectively, after 20 000 s of chronoamperometry. The results demonstrate a short SPP route and support-dependent alkaline ORR behavior, while highlighting the need for matched controls and interface-specific measurements to resolve the underlying mechanisms.
