General description

Copper(II) nitrate hemi(pentahydrate) is an inorganic copper salt.

Application

Copper(II) nitrate hemi(pentahydrate) may be employed as copper precursor for the preparation of thin film of Cu2ZnSnS4 (CZTS). It may be used in the preparation of 4-methoxypyridine-(pyridine-2,6-dicarboxylato-N,O,O′) copper (II) and in the synthesis of coordination pillared-layer frameworks (CPLs), particularly CPL-1, via mechanochemical method.

Derivatives of synthetic tetrahedrite, Cu12Sb4S13, are receiving increasing attention in the thermoelectric community due to their exploitation of plentiful, relatively nontoxic elements, combined with a thermoelectric performance that rivals that of PbTe-based compounds. However, traditional synthetic methods require weeks of
