Rechargeable Mg batteries are a promising post-Li-ion battery technology. In this work, reversible, aqueous Mg battery chemistry has been realized for the first time, via the conversion of its impermeable passivation film to a conductive metallic oxide complex, facilitated by Cl– regulation and the suppression of the hydrogen evolution reaction.

This paper systematically summarizes the research and development on photocatalytic oxidation (PCO) of VOCs, with emphasis on recent catalyst’s immobilization and reactor designs in detail. First, different types of photocatalytic materials and the mechanisms for PCO of VOCs are briefly discussed. Then, both the catalyst’s immobilization techniques and reactor designs are reviewed in detail. Finally, the existing challenges and future perspectives for PCO of VOCs are proposed.
