dc.description.abstract | 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 (R/R0 ranged from 2.5 to 7.4 % for concentrations of 100-500 ppm and 3 % relative humidity) with negligible cross-sensitivity towards H2 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. | en |
dc.description.abstract | V článku je oxid grafitu jako možná citlivá vrstva chemorezistivního senzoru na amoniak pracujícího při pokojové teplotě. Snímací vlastnosti byly testovány v širokém rozmezí koncentrací amoniaku ve vzduchu (10-1000 ppm) a při různé vlhkosti (3-65 %). Byl učiněn závěr, že senzor s oxidem grafitu vykazoval vysoké odezvu na NH3 v syntetickém vzduchu R/R0 v rozmezí 2,5 až 7,4 % pro koncentrace 100-500 ppm a 3 % relativní vlhkosti) se zanedbatelnou krossenzitivitou vůči H2 a CH4. Bylo zjištěno, že rychlost zotavení senzoru se zlepšovala s rostoucí koncentrace amoniaku. Zvýšení relativní vlhkosti prostředí vedlo ke zvýšení odezvy senzoru. Na úrovni relativní vlhkosti 65 % bylo dosaženo nejvyšší odezvy 22,2 % pro 100 ppm amoniaku. | cs |
