Assembly of antimony doped tin oxide nanocrystals into conducting macroscopic aerogel monoliths†
Abstract
We present the assembly of preformed antimony doped tin oxide nanobuilding blocks into centimeter sized aerogels with surface areas exceeding 340 m2 g−1. After calcination, the resistivity of the aerogels was decreased by 4 orders of magnitude to a few kΩ cm, with the primary conducting structures measuring only a few nanometers.
