Significantly enhanced UV-light-driven photocatalytic performance of ferroelectric (K0.5Na0.5)NbO3: Effect of corona-poling and particle size

Vidya Spriha Kujur et al.

Summary: This study focuses on the impact of corona-poling and particle size on the photocatalytic performance of (K0.5Na0.5) NbO3 (KNN) ferroelectric powder. The results demonstrate that the KNN-nano sample, with smaller particle size, exhibits better photocatalytic activity. The corona-poling treatment enhances the internal polarization field, leading to spatial separation of photogenerated electrons and holes and thereby providing more time for surface reactions, resulting in improved photocatalytic performance.

Investigation of structural, thermal, and electrical properties of magnesium substituted cobalt ferrite reinforced polyaniline nanocomposites

Swati et al.

Summary: In this study, PANI/MgxCo1-xFe2O4 (x = 0.2, 0.4, 0.6, 0.8) nanocomposites were synthesized using in-situ oxidation polymerization. Analysis confirmed the formation of nanocomposites and the construction of magnetic conducting phases in composite materials. The thermal stability, activation energy, dielectric properties, and AC conductivity of the materials were found to be influenced by the varying amount of magnesium contents, making them promising for high frequency applications.

Construction of multifunctional dual Z-scheme composites with enhanced photocatalytic activities for degradation of ciprofloxacin

Zuming He et al.

Summary: Visible-light-driven photocatalysis using magnetic recyclable dual Z-scheme NiFe2O4/Bi2WO6/AgI composites showed excellent photocatalytic performance for the degradation of ciprofloxacin compared to individual components. The 75%NiFe2O4/Bi2WO6/AgI composite exhibited the highest photocatalytic efficiency due to enhanced light absorption and dual Z-scheme transmission paths, suggesting its potential application in antibiotic wastewater treatment.
