▎ 摘 要
NOVELTY - A gas sensitive material comprises zinc oxide nano sheet and graphene oxide, where content of graphene oxide is 5-20 mass%. USE - Gas sensitive material for use in a gas sensor that is utilized for detecting acetone gas (all claimed). ADVANTAGE - The material has high acetone gas detecting sensitivity and selectivity, and reduces response time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing a gas sensitive material (2) a gas sensor (3) a method for preparing a gas sensor.
