NOVELTY - Synthesizing graphene quantum dots (GQDs) modified zinc oxide nanocomposite material involves adding different proportions of GQDs to porous zinc oxide nanosheets to prepare GQDs modified zinc oxide nanocomposites. USE - Method for synthesizing graphene quantum dots (GQDs) modified zinc oxide nanocomposite material for detecting dimethylamine gas. ADVANTAGE - The method enables to synthesize graphene quantum dots (GQDs) modified zinc oxide nanocomposite material has high sensitivity, high linearity, excellent selectivity, good repeatability to dimethylamine gas, and the lower limit of gas detection is 0.1ppm, which has great potential in the detection of dimethylamine gas.
