Summary: In this study, the optical properties and photothermal conversion performance of hollow and solid nanopillar structures based on different plasmonic materials (Ag, Au, Cu, TiN) were compared. The results show that hollow Au nanopillars exhibit the highest increase in photothermal conversion efficiency, by 34.14%. This enhancement is attributed to the promotion of local and propagating surface plasmon resonances in the hollow structure. Conversely, the increase in photothermal conversion efficiency for hollow TiN nanopillars is only 1.41%, as the solid TiN nanopillars already have high efficiency (97.19%). The hollow structure can enhance the photothermal properties of Plasmonic nanofluids, especially for precious metal materials with narrow-band absorption, such as Au and Ag.

Summary: This study proposes a hierarchical plasmonic structure as a photothermal substrate, incorporating a two-dimensional periodic microstructure with a disordered nanostructure. The microstructure and nanostructure were obtained through litho-etching and metal-assisted chemical etching technologies, respectively. Titanium nitride was used as a mediator, and the metallic nanostructure played a crucial role in generating the thermoplasmonic effect. Experimental results showed that the hierarchical plasmonic structures exhibited significantly higher photothermal efficiency compared to a titanium nitride film.

Summary: Solar energy is considered a vulnerable source in addressing environmental pollution and energy scarcity. Researchers have focused on converting solar energy into chemical energy through photocatalysis processes. Many discovered photocatalysts have limited absorption capabilities, particularly in the near-infrared light region, leading to efforts to improve photocatalytic reactions and utilize the full solar spectrum. Bismuth-based nanomaterials have shown potential as efficient photocatalysts for inclusive solar energy utilization, and this review discusses strategies to enhance their absorption of near-infrared light for improved performance.

Summary: Improving sunlight absorption and charge separation efficiency is crucial for TiO2 photocatalysts to achieve efficient CO2 photoreduction. In this study, a novel 0D/1D Cu2-xS/ TiO2 S-scheme photocatalyst was developed using a facile solvothermal approach. The optimized Cu2-xS/TiO2 photocatalyst exhibited significantly enhanced CH4 production rate compared to pristine TiO2, attributed to the improved charge separation efficiency and reduction ability. The Cu2-xS/TiO2 photocatalyst also displayed enhanced light absorption and remarkable photothermal effect due to the surface plasmon resonance effect of Cu2-xS. Furthermore, the mechanism of CO2 photoreduction over the Cu2-xS/TiO2 photocatalyst was investigated. Thus, this Cu2-xS/TiO2 S-scheme photocatalyst with photothermal effect provides valuable insights for designing full-spectrum-responsive CO2 reduction photocatalysts.

Summary: The photocatalytic cumulative effect of a semiconductor is important for its activity. This study demonstrates that by synthesizing a well-designed Au@Pt/CdS/C3N4 heterostructure, the photocatalytic cumulative effect can be enhanced. The coating of CdS nanoparticle-clusters and Pt nanoparticles onto the Au nanocubes increases the charge separation and charge migration processes. The two-dimensional Au/CdS/C3N4 interface and the quasi-2D porous structure of CdS nanoparticles enhance the light harvesting and charge utilization processes, respectively.

Summary: A polydopamine/defective ultrathin mesoporous graphitic carbon nitride (PDA/DCN) Z-scheme organic assembly was successfully fabricated through high-temperature surface hydrogenation and ultrasonic freeze-dried strategies. The assembly exhibited high photocatalytic hydrogen evolution and organic contaminant removal rates under visible and near-infrared light irradiation. The enhanced performance can be attributed to the defects of DCN that enhance interactions with PDA, leading to effective charge separation and rapid transfer. Additionally, PDA extends the photoresponse to the near-infrared region and induces photothermal effect, further increasing the reaction rate of the photocatalytic system.

Summary: Interface engineering is an efficient strategy to improve photocatalytic performance. In this study, reduced graphene oxide/mesoporous titanium dioxide nanotube heterojunction assemblies (rGO/TiO2) were fabricated via a hydrothermal method. The heterojunction interface formed between rGO and TiO2 nanotubes acts as efficient charge transfer channels, which leads to enhanced photocatalytic performance. The rGO/TiO2 heterojunction assemblies exhibit extended photoresponse to visible light and a significantly higher photocatalytic hydrogen production rate compared to TiO2 nanotubes alone. This enhancement is attributed to effective charge transfer channels, spatial charge separation, and the electron acceptor properties of rGO, as well as the large surface area and sufficient surface active sites provided by the two-dimensional mesoporous nanosheets structure. This heterojunction assembly holds potential applications in energy fields.

Summary: Doping engineering of metallic elements is important in photocatalysis, especially in the transition element range, as it increases carrier concentration and absorption in the light region. Mn doping changes the local structure of BiOCl, increasing the specific surface area and mesoporous distribution. The combination of Mn doping and metal Bi reduces the forbidden bandwidth, strengthening the photocatalytic ability. The dual-technology combination of Mn doping and Bi metal has promising applications in environmental remediation.
