Breaking the barrier: a MnWO4 photocatalyst enables solar chlorine production from seawater without noble metals

Abstract

Herein, we present a one-step hydrothermal synthesis approach towards the production of pure MnWO₄, which is driven by visible light to produce HClO. Significantly, our findings demonstrate the first successful implementation of noble-metal-free materials for photocatalytic chlorine production in natural seawater. This discovery has immense potential for various applications.
