中文摘要:
      采用多元醇法制备出均匀银纳米线,并详细讨论了温度、PVP与硝酸银物质的量比以及不同卤化物对银纳米线生长的影响。结果表明:当反应温度过低时,无法生成银纳米线,提高反应温度,银纳米线的长度增长;过高的反应温度会导致银纳米线长度不均匀,并降低银纳米线产率;适量的PVP可以促进银纳米线的生长,银纳米线的直径随PVP加入的物质的量的增加而减小;NaCl中Na+没有去氧能力,CuCl2中Cu2+去氧能力比FeCl3中的Fe3+去氧能力强,Br-促进了银单晶纳米立方块的生成。
英文摘要:
      Ag nanowires (Ag NWs) were synthesized by polyol method. The influence of temperature, molar ratio of PVP to AgNO3 and different metal halides on the growth of Ag NWs were studied in detail. The results show that Ag NWs can’t be synthesized when the temperature is too low. With the promotion of reaction temperature, the lengths of Ag NWs increase. When the temperature is too high, the lengths of Ag NWs are nonuniform and the yield of Ag NWs decrease. Moderate amount of PVP can promote the growth of Ag NWs. The diameters of Ag NWs decrease when the amount of PVP increases. Na+ does not have the ability of removing oxygen and the ability of removing oxygen of Cu2+ is better than that of Fe3+. Br- promotes the growth of mono-crystalline Ag nanocubes.
