Summary: Binary bentonite-water and ternary cement-bentonite-water systems were prepared to enhance the stability of fresh cement slurry for promoting bentonite as a low-cost viscosity modifying admixture. The interlayer ions of bentonite played crucial roles in improving the stability of cement slurry, and the performance of Ca2+ bentonite can be enhanced by introducing Li+. The effect of bentonite on the stability of cement slurry and its influencing mechanism were proposed based on the experimental results.

Summary: This study synthesized Eu:Bi2WO6 nanostructures with different concentrations of Eu ions and generated CdS on their surface to form Eu:Bi2WO6/CdS composites. The effects of Eu doping on the properties of the composites were studied, clarifying the mechanisms for improving optical and photocatalytic performance. The introduction of Eu3+ altered the band gap of the photocatalyst, while epitaxial CdS decreased recombination probability and improved photocatalytic activity. This research provides new insights for rational design and understanding of atomic-scale complex structures for applications in energy and environmental protection.

Summary: In this work, LaNiO3 epitaxial thin films were deposited on (001) single-crystal LaAlO3 and SrTiO3 substrates using polymer assisted deposition method. Additionally, LaNiO3 polycrystalline film was coated on ceramic substrate using LaNiO3 powder obtained from precursor solution in polymer assisted deposition. The lattice mismatch between LaNiO3 and single-crystal substrates results in the distortion of NiO6 octahedrons, which increases with the intensity of strain and enhances the visible-light photoconductivity.

Summary: CdS/ZnO composite nanoarchitectures were prepared by selectively decorating cadmium sulfide (CdS) nanoparticles on the highly active crystal planes of zinc oxide (ZnO). Different morphologies of CdS/ZnO nanoarchitectures were designed by regulating the shape of ZnO, which facilitated the separation of photogenerated electrons and holes. The nanoparticle/flower-like architecture exhibited excellent degradation performance, with a degradation rate for rhodamine B 8.3 times higher than that of pure ZnO. This work provides insights into designing and synthesizing high-efficiency visible light photocatalysts for treating wastewater with organic pollutants.

Summary: As an innovative semiconductor photocatalytic material, bismuth vanadate (BiVO4) has gained attention due to its narrow band gap, visible light response, and non-toxicity. However, the photocatalytic properties of BiVO4 are hindered by poor charge transport ability, slow water oxidation kinetics, and fast recombination of electron-hole pairs. This review summarizes the progress in designing heterojunction nano-materials based on BiVO4 for photocatalytic applications, including water splitting, organic matter degradation, CO2 reduction, and heavy metal ion reduction. Future development and prospects of BiVO4-based heterojunction nano-materials are also discussed.

Summary: The rational design of metal anchored on the carbon framework catalyst (M-N-C) is crucial for enhancing mass transfer and active site exposure in CO2 reduction reaction (CO2RR). In this study, prefabricated carbon nanotubes (CNT) were used as the carrier for M-N. The active center, M-N-C, was formed through controlled assembly and high-temperature nitriding between single-layer NiZn-layered double hydroxide (LDH) and CNT. The CNT-N-NiZn catalyst exhibited a high CO faradaic efficiency of 92.6% with a CO current density of 17.0 mA cm(-2) at -0.8 V vs. RHE in 0.5 M KHCO3 electrolyte. This study provides insights into the activity source and structure design of M-N-C catalysts.
