Transformation of bulk alloys to oxide nanowires

Transformation of bulk alloys to oxide nanowires

2017-1-20 · Many existing routes for making metal and metal oxide nanowires are complex require harsh solvents or are not easily scaled up. Lei et al. developed an extraction process to remove lithium from aluminum or magnesium alloys by using alcohol solvents. The resulting highly reactive Al or Mg atoms formed alkoxide nanowires which could be converted into oxides by high-temperature treatment.
