Summary: The development of plasmonics has led to the possibility of high-speed and highly sensitive optical sensors for analyzing chemical and biological media. In this study, the researchers demonstrate that the use of indium tin oxide (ITO) films with a high concentration of charge carriers can shift the surface plasmon resonance into the visible radiation region. The results show that SPR can be excited in ITO films with a concentration of free charge carriers, and the excitation wavelength of SPR can be changed by adding various analytes.

Summary: Photocatalysis triggered by visible light is an effective method for addressing environmental pollution and the energy crisis. Doping pure semiconductors with plasmonic metal nanoparticles can transform numerous metal oxide semiconductors into visible light active photocatalysts. In this study, we thoroughly investigated the photocatalytic properties of pure SnO2 nanoparticles and SnO2 doped with different percentages of 'Ag'. The results showed that 'Ag' doping significantly improved the photodegradation of methyl orange, and this enhancement was mainly attributed to surface defects and surface plasmon resonance effect caused by 'Ag' doping.

Summary: Unwelcomed biofilms are a problem in environments where moisture is present, such as food industries and wastewater treatment plants. Advanced label-free sensors like surface plasmon resonance (SPR) have been explored for monitoring biofilm formation, but conventional noble metal SPR substrates have limited penetration depth, hindering reliable detection. In this study, a plasmonic insulator-metal-insulator (IMI) structure with higher penetration depth was proposed for portable SPR devices. The optimized IMI structure showed strong penetration dependence on wavelength and incidence angle, providing more reliable results compared to thin gold film substrates. The methodology can detect and characterize biofilms with better signal reliability.

Summary: In this study, we for the first time observed and considered the plasmonic coupling between noble-metal and semiconductor nanostructures in metal/semiconductor heterostructures, using a W18O49/Ag heterostructure composed of Ag nanoparticles and W18O49 nanowires. The heterogeneous structure exhibited a broad and strong surface plasmon resonance (SPR) absorption in the visible wavelength range. Surface-enhanced Raman scattering (SERS) was used to investigate the interactions between metal SPR, semiconductor SPR, and the heterostructure's charge transfer process, revealing that the coupled SPR enhanced the heterostructure's internal charge transfer and SERS signals. A new coupled-plasmon-induced charge transfer mechanism was proposed to explain the improved charge transfer efficiency. This work provides insights for further studies on plasmonic effects and interfacial charge transfer in metal/semiconductor heterostructures.

Summary: This study developed a novel measuring and data-processing method for electrochemical surface plasmon resonance (EC-SPR), which can be used to detect sensor surfaces that are difficult to measure a specific SPR angle, especially for samples with non-uniform thickness and coloration like polymers. The proposed method combines SPR measurements with an electrochemical reaction to measure small molecules without increasing the number of measurement steps.

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: “The selective hydrogenation of furfural to furfuryl alcohol has attracted extensive attention, but designing and preparing efficient catalysts with high selectivity remains challenging due to the presence of conjugated C-O and C-C groups in furfural. In this study, small-sized Pt nanoclusters were loaded onto MOFs-derived CeO2 using atomic layer deposition. The Pt/M-CeO2 catalyst exhibited superior catalytic activity and selectivity compared to Pt/commercial CeO2, achieving 100% conversion of furfural with 98% selectivity to furfuryl alcohol. The excellent catalytic performance of Pt/M-CeO2 can be attributed to the clean surface of Pt clusters, strong interaction between Pt and M-CeO2, and the rich oxygen vacancy/porous structure of the M-CeO2 support. This work highlights an effective approach for depositing noble metal clusters onto MOFs-derived metal oxides, providing an alternative strategy for the rational design of highly efficient catalysts in selective hydrogenation reactions.”

Summary: In this study, a novel heterostructured piezo-photocatalyst was developed by decorating plasmonic Au nanoparticles on piezoelectric AgNbO3 nanocubes. The significantly enhanced photocatalytic performance of the optimized nanocomposites can be attributed to the synergetic coupling of localized surface plasmon resonance (SPR) effect and piezotronic effect, which facilitate the extraction of energetic hot electrons from AuNPs to the AgNbO3 driven by the mechanical vibration induced piezo-potential near the heterojunction.

Summary: In this study, a data-driven search method for two-dimensional covalent organic frameworks (COFs) capable of visible-light-driven overall water splitting was proposed. Through high-throughput first-principles computations and experimental validations, seven 2D COFs with overall water splitting capability were identified from the CoRE COF database. The photocatalytic activities of these COFs were verified and optimized through preliminary experiments, achieving hydrogen and oxygen production rates of 80 and 32 μmolg(-1) h(-1) respectively, without the need for sacrificial agents. This work represents a promising approach to accelerate the discovery and design of COFs for visible-light-driven overall water splitting.

Summary: In this study, graphene was added to Mg3.24Sb1.5Bi0.49Te0.01 materials to modify the highly resistive space-charge region at grain boundaries, leading to a significant improvement in carrier mobility and ZT value. The introduction of graphene effectively reduced the carrier transport energy barrier and increased the drift mobility. First-principles calculations revealed a negative correlation between the electronic density of states and the grain boundary potential barrier. Additionally, the incorporation of graphene also contributed to a moderate reduction in lattice thermal conductivity through nano-particle phonon scattering.
