| Abstract: | The paper focuses on the easy and fast synthesis of silver nanowires,and the catalysis activity of for oxygen electroreduction reaction.AgCl,PVP,and ethylene glycol(EG) were used as soft-template,and reducing agent,respectively.And different aspect ratios of silver nanowires were synthesized with different seeds(AgCl and Ag).By the characterization of SEM,TEM and others,a large quantity of nanowire with a little of nanoparticles was achieved.It was found the aspect ratios of silver nanowires were about 200(... |
