Abstract
Abstract:
Graphene gas sensors have gained much scientific interest due to their high sensitivity,
selectivity, and fast detection of various gases. This article summarizes the research progress
of graphene gas sensors for detecting ammonia gas at room temperature. Firstly, the performance
and development trends of the graphene/semiconductor Schottky diode sensor are discussed.
Secondly, manufacturing methods and the latest developments in graphene field-effect
transistor sensors are reviewed. Finally, the basic challenges and latest efforts of functional ammonia
gas sensors are studied. The discussion delves into each sensor type's detection principles
and performance indicators, including selectivity, stability, measurement range, response time,
recovery time, and relative humidity. A comparative analysis is conducted to highlight the progress
achieved in research, elucidating the advantages, disadvantages, and potential solutions
associated with various sensors. As a result, the paper concludes by exploring the future development
prospects of graphene-based ammonia sensors.
