Abstract

A protocol termed electrothermal chlorination is developed for the energy-efficient recovery of critical metals from electronic waste. The incorporation of direct electric heating into a chlorination process enables precise temperature control and rapid heating and cooling rates, facilitating metal separation based on subtle differences in thermodynamics as well as kinetic selectivity.
