Abstract This paper designed a green and simple method for preparing pure nitrogen dioxide gas in a closed container, which successfully integrated the gas preparation, collection, and exhaust gas treatment together. This method not only could be used for classroom demonstration experiments, but also laid the material foundation for further research on the quantitative experiment of nitrogen dioxide dissolving in water. In addition, this method could be used to prepare other substances in oxygen-free environment.
