Across the Board: Xinchen Wang

In this series of articles, the board members of ChemSusChem discuss recent research that they consider of exceptional quality and importance for sustainability. In this entry, Prof. Xinchen Wang discusses the investigations of a printable Z-scheme system for photocatalytic water splitting by the pioneer, Prof. Kazunari Domen, who has been constantly contributing to this field for about 40years. The recent achievement of an overall water splitting system has exceeded the solar-to-hydrogen energy efficiency of 1% by integrating efficient hydrogen and oxygen evolution photocatalysts with charge-transport channel.
