“…Their well-known optical behavior is associated with the localized surface plasmon resonance (LSPR) that arises from the collective oscillation of the metallic particle's electrons with the incident electromagnetic radiation. [21] This phenomenon is very sensitive to the environment, for example, when the refractive index near the NMNPs surface changes by the adsorption of molecules. [22] The resulting larger charge separation and a weaker restoring force lead to a red shift in the plasmonic band, which is the base for their application in nanoplasmonic biosensing .…”

Environmentally friendly methods for silver nanoparticles (AgNPs) synthesis without the use of hazardous chemicals have recently drawn attention. In this work, AgNPs have been synthesized by microwave irradiation using only honey solutions or aqueous fresh pink radish extracts. The concentrations of honey, radish extract, AgNO3 and pH were varied. AgNPs presented mean sizes between 7.0 and 12.8 nm and were stable up to 120 days. The AgNPs were employed as co‐catalyst (TiO2@AgNPs) to increase the hydrogen photogeneration under UV‐vis and only visible light irradiation, when compared to pristine TiO2 NPs. The prepared photocatalyst also showed hydrogen generation under visivel light. Additionally, AgNPs were used to assemble a nanoplasmonic biosensor for the biodetection of extremely low concentrations of streptavidin, owing to its specific binding to biotin. It was shown here that green AgNPs are versatile nanomaterials, being potential candidates for hydrogen photogeneration and biosensing applications.

Recently, novel 2D materials with fascinating characteristics are extensively applied to design/fabricate high‐activity and cost‐effective photocatalysts for solar‐driven fuels/chemicals generation. Among these 2D materials, HfS2 nanosheets (NSs) exhibit excellent features of large surface area, short bulk‐to‐surface distance, alterable band structures, and vast catalytic sites. Despite these features, no realistic experimental works on HfS2‐based materials are reported in photocatalysis field. Moreover, it is interesting but challenging to realize atomic‐scale engineering of compositions/structures for novel 2D materials and to relate these atomic‐scale characteristics with the element/space/time‐resolved charge kinetics of 2D materials‐based photocatalysts. Herein, for the first time, atomic‐scale defected HfS2 NSs are designed/synthesized. The as‐synthesized HfS2 NSs are combined with various photocatalysts to acquire novel HfS2‐TiO2, HfS2‐CdS, HfS2‐ZnIn2S4, and HfS2‐C3N4 composites, respectively. Among them, HfS2‐CdS exhibits the highest rate (5971 µmol g−1 h−1) on hydrogen (H2) evolution in triethanolamine aqueous solution, together with obviously‐enhanced rates on H2 (2419 µmol g−1 h−1) and benzaldehyde (5.11 mmol g−1 h−1) evolution in benzyl alcohol aqueous solution. Various state‐of‐art characterizations reveal the element/space/time‐resolved electron/hole kinetics in HfS2‐CdS composites, disclosing that these atomic‐scale S vacancies temporarily trapping electrons to facilitate spatiotemporal electron–hole separation/transfer. This work paves avenues to atomic‐scale design/synthesis of new 2D‐materials‐based photocatalysts for sunlight utilization.
