Copper Hydroxide - Digitalfire

Copper Hydroxide has a fairly complex decomposition as it is heated to melting point. Around 185C it loses about 18% weight as it decomposes to the heat stable CuO (cupric oxide) which remains stable until 1000C. Around 1050C about 6.5% is lost, likely involving partial loss of oxygen to form a mix of cuprous and cupric oxides.

Previous work showed that the copper oxide nanoparticles confined in titania nanotubes (Cu-in-TiO 2 NT) can effectively enhance the water–gas shift (WGS) activity. The WGS activity is directly related to the concentration of active copper species and oxygen vacancies (O v).The addition of potassium is found to enhance WGS activity of copper catalysts to some extent.
