Summary: The present study investigates the thermal stability and photocatalytic activity of TiO2-based nanotubes after post-hydrothermal treatment. It is found that post-hydrothermal heating improves the photocatalytic activity of the nanotubes by changing their phase structure and morphology. The holes and hydroxide ions are found to play a key role in the dye removal process. Additionally, the photocatalyst exhibits excellent stability and reusability.

Summary: This study investigated the synthesis, characterization, and thermal stability of pure and Al ion-exchange titanate nanotubes (Na2Ti3O7 and NaxAlyTi3O7, respectively). The results revealed the obtainment of sodium titanate and aluminum titanate nanotubes with different average lengths and diameters. The presence of Al ions in the crystal lattice affected the energy exchange between the unpaired species and the lattice. The thermal stability of sodium titanate nanotubes was influenced by sodium ions, while the incorporation of Al3+ ions into the nanotube lamellae decreased the thermal stability of aluminum titanate nanotubes.

Summary: This study proposes the modification of potassium titanate particles with magnesium in order to investigate their photocatalytic properties in the photodegradation reaction. The optimal amount of 4 at.% magnesium was found to result in the particles with the largest specific surface area and highest dye removal capacity.

Summary: Direct hydrothermal synthesized H-Titanate nanotube catalysts (H-TiNTs) were prepared and evaluated for the oxidation of dibenzothiophene (DBT) in model diesel. The effects of adding model components of 1-octylene, xylene, or cyclohexane in real diesel for sulfur removal were also evaluated. The results showed that the removal of DBT was maintained at nearly 100% under optimal conditions.

Summary: This work reports the effects of oleic acid as a surfactant on the growth properties of hydrothermally-synthesized BaTiO3 films by chemical modification of Ti sheets. The micro-structural properties and chemical composition were studied using XRD, XPS, and SEM. This study provides an interesting starting point for the future synthesis of nanostructured BaTiO3 thin films with optimized properties for potential applications in Flexible Capacitors (FCs).

Summary: The coupling of the piezoelectric effect and photocatalytic process promoted the separation of photogenerated carriers, thus increasing the piezo-photocatalytic activity. BaTiO3 nanoparticles were prepared on the Ti3C2Tx surface, and the obtained BaTiO3/Ti3C2Tx piezo-photocatalysts exhibited rapid electron transfer and a wide visible light response range. These results demonstrate that coupling piezoelectric and photocatalytic properties has broad application prospects in water pollution control.

Summary: The effects of ascorbic acid treatment alone and in combination with degreasing or hydrothermal treatment on improving the poor mouthfeel and low digestibility of brown rice were studied. The results showed that combining degreasing with ascorbic acid hydrothermal treatment significantly improved the texture of cooked brown rice, reducing hardness and chewiness to the level of polished rice, increasing stickiness, and enhancing sensory score and in vitro digestibility. The study also found that treated brown rice had reduced relative crystallinity and water contact angle, and increased water uptake. Scanning electron microscope showed starch granule separation in cooked brown rice grain. The improved eating quality and digestibility of brown rice is beneficial for consumer acceptance and human health.

Summary: This study successfully degraded and mineralized CBZ using AMnTi composite material, increasing the degradation rate of CBZ. The high catalytic activity of AMnTi is attributed to its unique structure, leading to efficient charge transfer and catalytic activation through Mn-O-Ti linkage, and a Mn-Ti cycle mediating catalytic activation of PMS was discovered. Both hydroxyl and sulfate radicals played key roles in CBZ degradation.
