SnO<inf>2</inf>nanowires mixed nanodendrites for high ethanol sensor response
Mixed morphology of SnO2nanowires and nanodendrites was synthesized on the gold-coated alumina substrates by carbothermal reduction of SnO2in closed crucible. The products were characterized by scanning electron microscopy, x-ray diffractometer, and transmission electron microscopy. Results showed t...
