| Abstract: | Taking USY sieve sorbent as a template,Ni(OH)2/USY composite was synthesized by means of liquid-precipitation,and its microstructure was analyzed and characterized with X-ray diffraction and transmission electron microscopy.The result showed that highly dispersed and loosely packed Ni(OH)2 whiskers on a nanometer scale possessed such characteristics as a good electrochemical accessibility of electrolyte ions and fast diffusion rate.It was shown by the test for its characteristics of cyclic voltammetry and c... |
