Abstract
The key to electrocatalytic water splitting is the discovery of efficient, low-cost electrocatalysts for oxygen evolution reaction (OER). g-C3N4@Co(OH)2 + PA/X nanowire materials were prepared by a combined strategy of thermo-hydraulic and DBD plasma modification. The morphological structure of the plasma modification for 60 s was then characterised by SEM and TEM patterns. In alkaline media, the g-C3N4@Co(OH)2 catalyst subjected to 60-s plasma treatment had excellent durability and exhibited outstanding electrochemical performance, displaying a low overpotential (329 mV). The number of Co3+ active sites, high conductivity, and large surface area of the g-C3N4@Co(OH)2 + PA/60s catalyst contribute to the remarkable OER activity. This research offers a novel approach to rationally designing effective electrocatalysts for water splitting.
