context_page_description: Hopkalite is the trade name for a number of mixtures that mainly consist of oxides of Copper and Manganese, which are used as catalysts for the conversion of Carbon monoxide to Carbon dioxide when exposed to the oxygen in the air at room temperature.
  The name "Hopcalite" is derived from Johns Hopkins University - "Hop" and the University of California - "Cal", where basic research into carbon monoxide was carried out during the First World War and these catalysts were discovered in 1918.
  A variety of compositions are known, such as "Hopcalite II" that is approximately 60% manganese dioxide and 40% copper oxide and "Hopcalite I" that is a mixture of 50% MnO, 30% CuO, 15% Co₂O₃, and 5% Ag₂O. Hopcalite has the properties of a porous mass and resembles activated carbon in its appearance.

  A variety of compositions are known, such as "Hopcalite II" that is approximately 60% manganese dioxide and 40% copper oxide (the MnO₂ : CuO molar ratio is 1.375) and "Hopcalite I" that is a mixture of 50% MnO, 30% CuO, 15% Co₂O₃, and 5% Ag₂O. Hopcalite has the properties of a porous mass and resembles activated carbon in its appearance.
