Highly sensitive acetone gas sensors are used for the purpose of air quality control, projection of environmental patterns, health monitoring programs, and many more. Because of its versatile application, several options for the fabrication of acetone gas sensors have been proposed, and this review will be focusing on graphene as its main component. Within the field of semiconducting, silicon has played an important role especially in sensor manufacturing and the prospect of replacing it with more affordable alternatives such as graphene is being openly considered. Hence, the review serves as the platform to discuss available graphene-based acetone gas detection system by evaluating sensor performance based on its selectivity, sensitivity, sensing performance, and correlates observed and reported mechanisms to possible physical and chemical attributes. To conclude this topic, several suggestions and solutions will be given overcome problems faced by groups dealing with graphene-based sensors.
