We report the electrochemical charge storage performance of NiSbO, obtained through a solid-state reaction method, and a detailed comparison with its reduced graphene oxide composite. Intriguingly, the composite, NiSbO-reduced graphene oxide, yielded a large capacitance of 952.38 F g, at a mass-normalized-current of 1 A g, which is at least 4-fold higher than that of the bare NiSbO.

Article Synopsis
  • Nickel ferrite (NiFeO) and magnetite (FeO) are affordable materials known for their magnetic properties and high photocatalytic activity, which have been combined to create a new composite (M@NFOPCN) using a straightforward coprecipitation method followed by calcination.
  • The resulting M@NFOPCN composite effectively enhances photocatalytic performance through controlled variations in the weight percentage of FeO, which improves characteristics like textural features and internal strain.
  • This innovative composite achieved nearly 90% degradation of the ciprofloxacin antibiotic under visible light, demonstrating its potential as a reusable, low-cost, and eco-friendly photocatalyst for environmental applications.
