Summary: This paper systematically investigates the ammonia (NH3)-sensing performance of phosphorus-doped graphene sensors. Stable phosphorus doping of graphene was achieved by using phosphorus pentoxide as the phosphorus source through chemical vapor deposition (CVD) at 480 oC. The results showed that phosphorus-doped graphene increased the NH3 response by 2.4 times on average, shortened the response (recovery) time by 70.6% (73.4%) on average, and had a theoretical limit of detection (LOD) of 68.76 ppb. The phosphorus-doped graphene sensor also exhibited excellent repeatability, stability, and ultra-high selectivity to NH3.

Summary: Carbon dots (CDs) obtained from waste produced during the production of olive oil have been investigated as a gas sensing material for the detection of nitric oxide (NO) in air. The response to NO was selective and promising, with different responses observed for CDs prepared from different geographic locations. The selectivity was attributed to the specific interactions between different functional groups on the CDs surface and NO/NO2.
