ABSTRACT:
A method for forming a copper oxide catalyst includes forming a precipitate of copper hydroxide from a copper salt solution; forming dried particles of copper hydroxide by drying the precipitate at a temperature of less than 30° C.; heating the copper hydroxide particles to form copper oxide; and activating the copper oxide. The copper oxide catalyst includes particles of copper oxide. Copper oxide catalyst particles can preferably include a metastable form of copper oxide. The copper oxide catalyst particles are useful for low-temperature and near-ambient temperature catalysis and/or oxidation of carbon monoxide to carbon dioxide.
