▎ 摘  要

NOVELTY - Preparing purple phosphorene/graphene gas sensor, comprises combining phosphorene and graphene by vacuum filtration method to obtain phosphorene/graphene composite material, and coating conductive electrode. USE - The purple phosphorene/graphene gas sensor is useful in detecting 10-50 ppb level formaldehyde at room temperature (claimed). ADVANTAGE - The purple phosphorene/graphene gas sensor has good response to ppb grade formaldehyde gas at room temperature, and is safe and environment-friendly, large batch and high quality, and has high specific surface area, chemical active site and electrical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for purple phosphorene/graphene gas sensor.
