“…The peak positions of Pt@ZnO NFs exhibited a significant redshift relative to those of pristine ZnO NFs, which confirmed the electronic interaction (electrons transfer from ZnO to Pt) between Pt and ZnO. 39,40 Fig. 3f shows the Pt 4f XPS spectra of 5-Pt, 10-Pt, and 30-Pt, respectively.…”

“…The XPS spectrum of Ag 3 d contains two peaks at 367.7 and 373.7 eV, which correspond to the binding energies of Ag 3 d 5/2 and Ag 3 d 3/2 , respectively. [ 26 ] In addition, there was a significant blue shift in the peak positions of Ag3 d 5/2 and Ag 3 d 3/2 compared to the standard AgNWs samples (368.2 eV for Ag 3 d 5/2 and 374.2 eV for Ag 3 d 3/2 ), [ 27 ] indicating that the presence of electron transport at the interface of AgNWs and ZIF‐8. To further confirm this electron transportation, the Zn 2 p peak's high‐resolution scan spectra are presented in Figure 5b.…”

Due to the wider bandgap and low electron discharge capacity, the zeolitic imidazolate framework (ZIF‐8) shows low photocatalytic performance compared with conventional semiconductor materials. To enhance the photocatalytic activity of ZIF‐8, the ZIF‐8@AgNWs composite is synthesized via the in situ growth method using silver nanowires (AgNWs) as the photo‐enhanced material. The obtained ZIF‐8@AgNWs exhibit the fully encapsulated shell‐core structure of ZIF‐8‐AgNWs. The UV−vis diffuse reflectance spectroscopy (DRS) analysis shows that the addition of AgNWs leads to a significant increase in light absorption of the ZIF‐8@AgNWs composite, and the bandgap of the ZIF‐8@AgNWs is 2.9 eV, with a significant decrease compared to pure ZIF‐8 (4.96 eV). The ZIF‐8@AgNWs‐2 achieves the best photocatalytic activity for methylene blue (MB) degradation. Its degradation eﬃciency reaches 94%, and its apparent rate constant is 0.04371 min−1. Herein, a novel strategy for the MOF‐based photocatalytic materials with higher photocatalytic activity is provided.

Many technological approaches have been searched in order to overcome the main challenges concerning the world energy crisis and global environmental issues. Among them, plasmon‐driven photoelectrochemical reactions towards water electrolysis attract great attention due to their capacity to efficiently harvest solar energy. Synergism between tunable optical features and catalysts active sites of plasmonic nanomaterials gives rise to a singular perspective for photochemical processes. Through resonant photonic excitation, hot carriers’ motion facilitates the charge transfer process on the catalyst surface for chemical reactions. In this minireview, recent experimental research with emphasis on water splitting reactions have been summarized with the purpose of understanding the mechanistic hot electrons generation and transfer on the plasmonic noble metal nanoparticles (MNPs) and transition metal oxides (MOs) heterostructures. Examples of plasmonic nanomaterials are highlighted and compared for both water electrolysis semi reactions. Finally, this work concludes by describing the remaining challenges and gives some perspectives regarding the promising future of plasmon‐driven reactions investigations.
