Summary: This study presents a trifunctional Schottky junction at metal-photocatalyst heterointerfaces, which effectively enhances the performance of photocatalysts for hydrogen production under visible light. The Schottky junction, involving chemically stabilized ultrafine platinum nanoparticles on graphitic carbon nitride nanosheets, promotes efficient interfacial charge transfer and prevents aggregation of the nanoparticles during photocatalytic reactions. The results demonstrate an over 11-fold enhancement in visible light H2 production compared to the control sample. These findings highlight the potential for developing high-efficiency photocatalysts through strong metal-semiconductor electronic interactions.

Summary: The creation of yolk-shell nanoparticles (YS NPs) with a movable core and periodic mesoporous organosilica (PMO) shell has been simplified using a self-template strategy. A ratiometric Cu2+ fluorescence sensor is created by incorporating a silver nanocore into the YS NP (Ag-PMO-YS), driven by the like dissolves like principle. Due to the coordination of Cu2+ and its ligands and their impact on the emission of fluorescein derivatives, this sensor system demonstrates extraordinary detection sensitivity to Cu2+ (10-7 M), strengthened by the movable Ag nanocore's metal-enhanced fluorescence (MEF) effect.

Summary: Incorporating plasmonic metal nanomaterials into semiconductor photocatalysts enhances their visible light response through localized surface plasmon resonance (LSPR) mechanisms. However, the presence of surfactants on the surfaces of plasmonic metal nanomaterials hinders their cocatalyst functionalities for photocatalytic hydrogen evolution. This study demonstrates a surfactant-free method to assemble Au nanoparticles (NPs) into Au colloidosomes (AuCSs), which can act as efficient cocatalysts when coupled with CdS to form Au-CdS composite photocatalysts.

Summary: By combining the localized surface plasmon resonance (LSPR) of metallic Ag and the chemically reactive Pt co-catalyst, a Ag-Pt bimetallic composite was coated on exfoliated defective graphitic carbon nitride nanosheets (C3N.NS) for plasmon hot electron-mediated photocatalytic H2 evolution. The (1:2) Ag-Pt/C3N.NS sample showed the highest activity (1.25 mmol g-1 h-1) under visible light irradiation, which was 35.7 and 1.7 times higher than that of Ag/C3NX NS and Pt/C3NX NS, respectively. The apparent quantum efficiency (AQE) of (1:2) Ag-Pt/C3NX NS reached 3.3% at 420 nm. The boosted photocatalytic capacity was attributed to the advantages of the LSPR effect of Ag particles and the Schottky barrier between Pt and C3NX NS, resulting in more electrons participating in the reduction reaction to enhance the photocatalytic H2 evolution performance.

Summary: Traditional defect engineering and doping strategies are commonly used to enhance H-2 evolution, but their uncontrollability may not always result in efficient activity. This study presents a defect-induced heteroatom refilling strategy to synthesize carbon nitrides with controlled heteroatom introduction on efficient N1 sites. The refilling of B, P, and S sites shows stronger H2O adsorption and dissociation capacity compared to traditional doping, making it an optimal pathway for H-2 production. The heteroatom-refilled catalysts exhibit a high internal electric field strength, enabling fast electron transfer and achieving a hydrogen production rate of up to 20.9 mmol g(-1) h(-1). This work provides insights into controlled defect engineering of photocatalysts and offers a universal modification strategy for heteroatoms and co-catalyst systems in H-2 production.

Summary: Achieving carbon neutralization by CO2 photoreduction (CO2PR) has attracted extensive attention, but limited selectivity and harsh reaction conditions hinder its practical application. In this study, the authors introduced ammonia borane (AB) as mild proton-electron pair donors to realize synergistic hydrogen evolution and selective photocatalytic CO2 reduction to formic acid. Promising results were obtained, and the use of AB as a *H donor showed potential in accelerating the selective generation of formic acid. Furthermore, other similar *H donors also exhibited good performance, providing guidance for the design of high-performance CO2PR systems in the future.

Summary: Surface-enhanced Raman spectroscopy (SERS) is a powerful technique used in various research fields. Semiconductor SERS substrates, as alternatives to plasmonic metal substrates, have attractive attributes. However, they can only enhance the signals of analytes chemically adsorbed on their surface. In this study, we demonstrate the detection of non-adsorbing analytes on ZnO nanoparticles by coating them with ZIF-8 shells, which significantly enhances their electromagnetic enhancing capability and enables the detection of a wider range of non-adsorbing analytes.
