| 英文摘要 | an (oxy)nitride-based heterostructure for powdered z-scheme overall water splitting is presented. compared with the single mgta2o6-xny or taon photocatalyst, a mgta2o6-xny/taon heterostructure fabricated by a simple one-pot nitridation route was demonstrated to effectively suppress the recombination of carriers by efficient spatial charge separation and decreased defect density. by employing pt-loaded mgta2o6-xny/taon as a h-2-evolving photocatalyst, a z-scheme overall water splitting system with an apparent quantum efficiency (aqe) of 6.8% at 420 nm was constructed (ptox-wo3 and io3- /i- pairs were used as an o-2-evolving photocatalyst and a redox mediator, respectively), the activity of which is circa 7 or 360 times of that using pt-taon or pt-mgta2o6-xny as a h-2-evolving photocatalyst, respectively. to the best of our knowledge, this is the highest aqe among the powdered z-scheme overall water splitting systems ever reported. |
