Summary: A novel rodlike AgCl/Ag/In2O3 plasmonic photocatalyst was successfully prepared and showed efficient photocatalytic activity under visible light irradiation, with AgCl/Ag/In2O3-2 exhibiting the highest performance. The superior activity was attributed to localized surface plasmon resonance (LSPR) and efficient charge migration and separation.

Summary: Efficient visible light photocatalytic elimination of pharmaceutical factory wastewater was achieved by introducing hybrid Ag/AgCl nanoparticles into Ti3+ self-doped TiO2 mesocrystals. The Ag/AgCl@Ti3+-TiO2 mesocrystals showed superior performance in degrading tetracycline under visible light, mainly attributed to the continuous attacks of photo-generated holes and radicals on tetracycline molecules.

Summary: Here we report the optimized route for the synthesis of zero valent silver loaded silver zirconate (Ag/Ag2ZrO3) nanocomposite, which enhances the visible light harvesting ability of silver zirconate (Ag2ZrO3) through the surface plasmon resonance (SPR) effect. The effect of surfactant on the formation of the nanocomposite and bare Ag2ZrO3 has been studied. The synthesized nanocomposite and Ag2ZrO3 have been confirmed by various analysis methods, and the nanocomposite shows higher degradation efficiency and the presence of reactive species compared to bare Ag2ZrO3.

Summary: This study demonstrated a rapid and efficient control method to prevent the spread of Aspergillus flavus spores in air using plasmonic composites. The composites, composed of Ag-AgCl nanoparticles and tetrahedral alpha-Fe2O3, showed a prevention rate of 93.65 +/- 1.53% under visible light irradiation. The prevention activity was attributed to the intrinsic disinfection, electron sink, and localized surface plasmon resonance effect of Ag. The composites also exhibited high activity (90.52 +/- 1.26%) in preventing Aspergillus flavus spore spread during peanut storage. These findings provide useful strategies for preventing Aspergillus flavus contamination and controlling toxic fungi.

Summary: The novel plasmonic Ag/AgCl@LaFeO3 (ALFO) photocatalyst showed enhanced photocatalytic activity in controlling harmful algal blooms (HABs) under visible light. ALFO-20% demonstrated higher light absorption capacity and lower electron-hole recombined rate compared to pure LaFeO3 and Ag/AgCl. Furthermore, ALFO-20% efficiently removed chlorophyll a from HABs, altered algae cell membrane permeability and morphology, disrupted photosynthesis and antioxidant systems, reducing secondary pollution and preventing HAB recurrence.

Summary: Ag/AgCl-TiO2 plasmonic nanocomposites with excellent visible-light photocatalytic activity were synthesized using a green and cost-effective approach. The synthesized nanocomposites showed significantly higher degradation rates of methyl orange (MO) compared to TiO2 under visible light. Among them, the sample with a 15% Ag/TiO2 molar ratio exhibited a MO degradation efficiency higher than 99% and maintained high photocatalytic activity even after several degradation runs. This study provides a novel and more sustainable strategy for the efficient modification of TiO2 photocatalyst in engineering and environmental applications.

Summary: A string of AgCl/Bi3TaO7 two-component composite was synthesized and it showed great potential for photocatalytic oxidation of residual tetracycline (TC) in wastewater effluents. The AgCl/Bi3TaO7 nanocomposites exhibited a higher photocatalytic efficiency for TC dissociation compared to single Bi3TaO7 and AgCl. The improved photocatalytic activity was attributed to the unique construction of Z-scheme AgCl/Bi3TaO7 heterojunction which enhanced charge separation and transmission.

Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
