【 摘 要 】

Real-time ammonia (NH3) detection in anaerobic digestion is highly desirable, due to the ammonia inhibition on methane production. Here, the interconnected nanocomposite network of polyaniline (PANI) nanoparticle-coated carbon nanotube (CNT) and PANI nanofiber is fabricated by adding ammonium per sulfate into CNT-containing aniline solution for PANI polymerization and film deposition. The film is assembled as high-sensitive ammonia sensors, exhibiting highly sensitive NH3 sensing from 200 ppb to 50 ppm, fast response/recovery time, room-temperature operation without external aid, reliable flexibility and excellent selectivity to NH3 compared to other volatile organic compounds.
