[Display omitted] •Novel hierarchical SiCN photocatalyst has been prepared via the combination of ball milling and heat treatment techniques.•The SiCN nanowires show an RhB degradation of ∼99% in 40 min under visible light illumination.•The photocatalyst exhibits an extremely high photocurrent current and long-term photostability, strongly depended on the type of electrolyte.•188 mFcm−2 specific capacitance of the SiCN nanowires was achieved. We synthesized SiCN nanowires by a combination of high-energy ball milling and post-heat treatment using high-purity silicon and carbon nanopowders (
