Synthetic control of composition and crystallite size of silver ferrite composites: profound electrochemistry impacts

A paradigm for concomitant control of crystallite size and composition of bimetallic composites via co-precipitation is introduced. Direct preparation of composites of silver ferrite and amorphous maghemite via nonstoichiometric synthesis was demonstrated. Notable impact on electrochemistry was observed, with similar to 200% increase in reversible capacity for the small crystallite material.
