Efficient electron-induced removal of oxalate ions and formation of copper nanoparticles from copper(II) oxalate precursor layers

Copper(II) oxalate grown on carboxy-terminated self-assembled monolayers (SAM) using a step-by-step approach was used as precursor for the electron-induced synthesis of surface-supported copper nanoparticles.The precursor material was deposited by dipping the surfaces alternately in ethanolic shiro neon zero solutions of copper(II) acetate and oxal
