Summary: Hierarchical micro/nanostructures assembled from nanorods and nanosheets have been fabricated by a two-step solvothermal process, resulting in Cd-Ni-MOF structures with different morphologies. Hybrid micro/nanostructures of Cd-Ni-MOF-T/CdS/NiS were synthesized by exchanging Ni2+ and Cd2+ of Cd-Ni-MOFs with S2-. The as-prepared samples composed of thin nanosheets alone exhibited the highest photocatalytic H-2 evolution rate. The CdS-NiS p-n junction and CdS-Cd-Ni-MOF-T heterojunction were found to enhance the transfer of photogenerated electrons, leading to improved photocatalytic activity.

Summary: Transition metal sulfides with mixed vulcanized states (TMS-mVs) have great potential in high-capacity and reversible metal-ion storage due to their multielectron reactions caused by the participation of transition metal cations and S-2(2-) anions as well as diverse TM or S valence states. This article introduces recent advances in mainstream TMS-mVs for M-n(+) storage. TMS-mVs can be categorized into TMS-mSs with mixed sulfur-valence states and TMS-mMs with mixed metal-valence states. The electrochemical performance of TMS-mVs can be enhanced through composite, coating, nanostructure, heterointerface, and lattice engineering strategies.

However, the influence mechanism of plasmon effects on CO2 photoreduction is still debated. This study used Au particles deposited on different substrates to investigate the plasmon photocatalytic CO2 reduction. The results showed that the plasmon resonant enhancement effect of Au-SiO2 was stronger than Au-TiO2-SiO2 and Au-n-Si (Au-p-Si) samples in the visible-light range.

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: A dispersion of black TiO2 photocatalyst was prepared and sprayed onto the concrete's surface, resulting in a black TiO2-based photocatalytic concrete paving eco-block with a higher photocatalytic NO removal ratio compared to a white TiO2-based eco-block. The black TiO2-based eco-block also exhibited enhanced compressive strength and abrasion resistance. In situ DRIFTS was used to investigate the reaction mechanism, showing no harmful by-products were produced during the photocatalytic removal of NO. A CFD model was constructed to assess the real-world applicability of the black TiO2-based photocatalytic eco-blocks in urban street coating. Overall, this research offers new perspectives on creating environmentally friendly photocatalytic products for air pollutant removal using solar light.
