In situ unravelling surface plasmon resonance subject-object role of BiVO@Ag in photocatalytic water splitting.

Surface plasmon resonance (SPR) of noble metal particles has been recognized to play a significant role in photocatalysis. We designed the BiVO@Ag system by photo-deposition to prove the special role of Ag nanoparticles (NPs) in promoting water splitting. The BiVO@Ag considerably increases light absorption by the SPR effect of Ag NPs.

Carrier confinement activated explicit solvent dynamic of CdS/BiVO/HO and optimized photocatalytic hydrogen evolution performances.

Herein, using an electrophoretic deposition strategy, a S-scheme CdS (cubic)/BiVO (monoclinic) heterostructured photocatalyst is fabricated. The as-synthesized photocatalysts exhibit high carrier separation efficiency, prominent hydrogen evolution ability and high stability. The results of the detailed density functional theory (DFT) prove that the photogenerated electrons and holes are located in BiVO and CdS components, respectively.

Electron confinement promoted the electric double layer effect of BiOI/β-BiO in photocatalytic water splitting.

In the realm of photocatalysis, understanding the interface issues (solid/solid and solid/liquid) inherent in heterojunction at the atomic level is the ultimate for engineering an efficient photocatalyst. Herein, an electrophoretic deposition technique is adopted to synthesize BiOI/β-BiO heterojunction, exhibiting superior photocatalytic activity and stability in H evolution (91.5 μmol g h) and HO production (11.
