TY - JOUR ID - 1371899 AU - Bannov, Alexander - Prášek, Jan - Jašek, Ondřej - Shibaev, Aleksandr - Zajíčková, Lenka PY - 2016 TI - Investigation of ammonia gas sensing properties of graphite oxide PB - Elsevier Science CY - Amsterdam, Netherlands KW - Gas sensor KW - ammonia KW - graphite oxide KW - response KW - humidity KW - cross-sensitivity UR - http://www.sciencedirect.com/science/article/pii/S1877705816334798 N2 - In this paper a graphite oxide is investigated as a possible sensing layer of room temperature ammonia chemiresistive gas sensor. The sensing properties were tested in a wide range of ammonia concentrations in air (10-1000 ppm) and under different humidity levels (3-65 %). It was concluded that the graphite oxide based sensor possessed high response to NH3 in synthetic air (Delta R/R-0 ranged from 2.5 to 7.4 % for concentrations of 100-500 ppm and 3 % relative humidity) with negligible cross-sensitivity towards H-2 and CH4. It was determined that the sensor recovery rate was improved with ammonia concentration growth. Increasing of ambient relative humidity led to increase of sensor response. The highest response of 22.2 % for 100 ppm of ammonia was achieved at 65 % relative humidity level. ER -
