Electrochemical investigation of NiCo double hydroxides for supercapacitors

NiCo-layered double hydroxides (NCLDH) synthesized by a simple one pot sol–gel process using propylene oxide as gelation agent. Synthesized material is investigated for its crystal structure, morphology including specific surface area and electrochemical performance as supercapacitor electrodes. The...
