General description

Copper(II) carbonate basic is naturally found in azurite and malachite.[1] On heating, it undergoes decomposition to form copper(II) oxide, carbon dioxide and water.[2] Due to its high initial discharge capacity, copper(II) carbonate (basic) is being considered as a promising candidate as anode materials for lithium-ion batteries.[3]

Application

Copper(II) carbonate basic (Cupric carbonate basic, Copper(II) basic carbonate) may be used in the preparation of colloidal copper.[4]
Copper(II) carbonate basic along with different ligands form an efficient catalytic system for ′on water′ β-borylation of Michael acceptors, alkenes and alkynes.[5]
