Abstract

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 ∼200% increase in reversible capacity for the small crystallite material.

摘要

介绍了一种通过共沉淀同时控制双金属复合材料微晶尺寸和组成的范例。展示了通过非化学计量合成直接制备铁酸银和无定形磁赤铁矿复合材料的方法。观察到对电化学有显著影响，小晶粒材料的可逆容量增加了约200%。
