WebAn (oxy)nitride-based heterostructure for powdered Z-scheme overall water splitting is presented. Compared with the single MgTa 2 O 6−x N y or TaON photocatalyst, a MgTa 2 O 6−x N y /TaON heterostructure fabricated by a simple one-pot nitridation route was demonstrated to effectively suppress the recombination of carriers by efficient spatial … WebNov 8, 2024 · Herein, we image directly the local separation of photogenerated charge carriers across single crystals of the BiVO 4 photocatalyst which loaded locally with nanoparticles of a MnO x single cocatalyst or with nanoparticles of a spatially separated MnO x and Pt dual cocatalyst. The deposition of the single cocatalyst resulted not only in …
