Synthesis and electrochemical properties study of novel intercalation compound of kca 2 nb 3 o 10 with cationic methylene blue

A functional layered nanocomposite, MB + -Ca 2 Nb 3 O 10 , was prepared by the intercalation of methylene blue (MB) into the layered material, KCa 2 Nb 3 O 10 , by a guest-exchange method using the n -PrNH 3 + -Ca 2 Nb 3 O 10 intercalation compound as an intermediate. The resultant nanocomposite was characterised by powder X-ray diffraction and infrared. Electrochemical studies reveal that the target hybrid retains the good redox activities of MB + cation and has potential utilisation in electrocatalytic reactions.
