Nano-Structuration of WO Nanoleaves by Localized Hydrolysis of an Organometallic Zn Precursor: Application to Photocatalytic NO Abatement.

WO is a known photocatalytic metal oxide frequently studied for its depollution properties. However, it suffers from a high recombination rate of the photogenerated electron/holes pair that is detrimental to its performance. In this paper, we present a new chemical method to decorate WO nanoleaves (NLs) with a complementary metal oxide (ZnWO) in order to improve the photocatalytic performance of the composite material for the abatement of 400 ppb NO under mild UV exposure.
