Hydrothermally processed SnO2 nanocrystals for ultrasensitive NO sensors†
Abstract
SnO2 nanocrystals have been successfully synthesized by a hydrothermal method assisted by biuret. When tested as the gas-sensing material, these hydrothermally processed SnO2 nanocrystals displayed an ultrasensitive response towards NO and ultrahigh selectivity due to their physicochemical nature.
