林逆承：镍基纳米材料的控制合成及性能研究 毕业设计（论文） PAGE PAGE IV 镍基纳米材料的控制合成及性能研究 摘 要 镍基纳米材料作为纳米材料中的一类重要复合材料，因为其在磁记录、催化剂、光伏电池、抗癌药物磁性载体等领域的广泛应用而成为研究的热点。本研究首先确定了合成镍纳米材料的有效方法和一些影响其合成的因素，然后通过以氢氧化镍为连续相复合其他物质来合成镍基纳米材料，并通过SEM、XRD、红外等方法对产物进行表征，同时测试其电化学性能。 通过相关的XRD和红外的表征可知实验所得的复合材料产物即为目标产物。而且还检测了该复合材料的电化学性能，结果表明所得的复合材料具有良好的电化学性能，有可能通过进一步研究得以应用于实际。 通过实验探究得知在合成纳米镍的反应体系中加入NH4Cl会得到内部呈网状结构的球状纳米Ni(OH)2，未添加时所得产物呈无规则的花瓣状。以Ni(OH)2与吡咯聚合所得的复合产物进行电化学性能测试，得出此复合材料的电化学性能较氢氧化镍有明显的提升。再通过改变或优化实验条件应该可以继续提升复合材料的性能，使其具有更高的实用价值。 关键词：氢氧化镍；吡咯；复合材料；电化学性能；应用 Control study on Synthesis and properties of nickel based nano materials Lin nicheng (College of Biology and Chemical Engineering, Anhui Polytechnic University,Wuhu,Anhui,241000) Abstract Nickel base nano materials as one of the most important composite materials in nanometer materials, due to its stable chemical properties has extensive application in many ways. Because of its in magnetic recording, catalyst, photovoltaic cells, anti-cancer drugs are widely used in the field of magnetic carrier, etc and become the research hot spot ，This study first determine nanomaterial synthesis nickel effective method and some factors affecting the synthesis, and then studied with nanometer nickel as continuous phase composite material for synthesis of other nickel base the electrochemical properties of nanomaterials. By SEM, XRD, ir and other methods of product have been characterized, at the same time to test its electrochemical performance. Through related characterization of XRD, ir is the experiment of the composite materials of product is the target product. But also detect the electrochemical properties of the composites, the results show that the composite material has good electrochemical properties, may by further research to application. Obtained by the experimental study of the synthesis of nanometer nickel to join in the reaction system of NH4Cl will
