Nanowire‐based branched nanotrees prepared by flame vapor deposition system incorporated with double wire feeders

Abstract

SignificanceWe developed a facile approach for fast growth of branched nanotrees in a newly designed double‐wire‐feeder incorporated flame vapor deposition system. Nuclei formation on preformed nanowires for branch growth is innovatively done by traversing horizontal wire across flame. The density of nanobranches and resultant morphology of branched nanotrees could be tuned through a precise control over wires‐feeding pattern. The entire process can be done coherently without necessity of other process involvement or any interruption. © 2019 American Institute of Chemical Engineers AIChE J, 65: 1138–1143, 2019
