▎ 摘　　要

NOVELTY - A gas sensing material comprises graphene oxide doped zinc oxide nanosheet having a mesoporous structure on its surface. USE - Gas sensing material for use in gas sensor for detecting acetone (claimed). ADVANTAGE - The gas sensing material can be prepared with high sensitivity, better selectivity, strong interfering gas/recovery ability, stable performance, rapid response, and better effect of improving the sensitivity and selectivity of acetone gas sensor. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing gas sensing material (2) a gas sensor.
