Preparation and thermal decomposition of Cu2(OH)3NO3

The decomposition of basic copper nitrate is studied using TG-FTIR. The product is decomposed between 160 and 235°C at a heating rate of 10°C min−1. The solid residue is CuO and the gases evolved during decomposition are HNO3, H2O, NO2 and O2. Decomposition seems to occur in one step.
