Abstract

Mechanical activation is found to enhance the reactivity of copper powder with acetic acid. The milling-induced increase in the thermal effect of the reaction between Cu and acetic acid is shown to be associated with the activation of the molecular oxygen involved in the reaction. The activation is due to the presence of lattice oxygen with increased bond energies.
