Abstract
Description
Technical field
[0001] The present invention is a new preparation method, and the corresponding catalytic material prepared by the preparation method can purify CO in the environment at low temperature or even normal temperature. Its application range includes coal mine self-rescuers against CO, high-rise building escape masks, or other devices used to protect CO, CO 2 Lasers, CO sensors, and CO purification in some special or enclosed environments. Background technique
[0002] The CO purification catalyst material used for a long time in the past was Hopcalite. It was jointly invented by Johns Hopkins University and the University of California in 1919. It is a catalytic material made of active manganese dioxide and copper oxide in a certain proportion. Generally, the preparation method of Hopcalite catalytic material is the sulfuric acid method. The first step is to produce active manganese dioxide, which is to mix manganese sulfate fine powder (below 70 mesh) with a small amo...
