碩士 === 南台科技大學 === 機械工程系 === 101 === The purpose of this study was using a novel and simple synthetic strategy for fabricating superparamagnetic nanomagnets randomly dispersed in porous carbons. The method can basically be regarded as a pyrolysis performed inside the restricted volume formed by the pores of an activated carbon. The additional advantage of this method is its versatility, that allow the composite material with adjustable magnetic properties to be obtained. In this way, it is possible to obtain superparamagnetic composites which can be easily manipulated by an external magnetic field. This study use the active carbon impregnated with a solution of other nitrates material. The porosity of the active carbon was filled with a solution of other nitrates material.The sample was prepared a iron or iron-cobalt-nickel , its alloys and activated carbon composite by heat treatment under high temperature to synthesize. And using X-ray diffraction (XRD) or other equipment to study the analysis of the sample. This article describes the transition metal alloy and the nano-composites of the activated carbon. Its research advance in the synthesis and physical properties, including the contents of its structural characteristics, physical characteristics, and its applications.
