The supported alumina catalysts used were in the form of copper(II), cobalt(II), … Afterwards, the piece was left to air dry. This can be represented as: 4Cu + O2 = 2Cu2O (copper oxide) —- equation 1. If the atmosphere consists of high humidity moisture, then this process is faster. If you are using wire, make sure it is uncoated. You can add more hydrogen peroxide to keep the reaction going longer. This compound, also known as cuprous oxide, occurs naturally in some parts of the world as the mineral cuprite. Oxidation is a phenomenon, whereby an element loses electrons (and/or hydrogen) on interacting with another element. Many homeowners mistake the green discoloration for mold.
