Summary: The origin of the improved performance of erbium-doped TiO2 film via the hydrothermal doping process is the change in the dominant facet of rutile TiO2 upon doping, resulting in co-exposed {10 1}/{1 1 1} facet. This change in facet leads to variations in surface energy levels of conduction band (CB) and valence band (VB) on different crystal surfaces, preventing electron-hole recombination.

Summary: The synthesis of N-doped TiO2 film with co-exposed {101} and {111} facets via a one-pot facile hydrothermal method has been found to enhance the photocatalytic activity of TiO2. The incorporation of N ions into TiO2, as confirmed by high-resolution transmission electron microscopy (HR-TEM) and X-ray photoelectron spectroscopy (XPS), results in facet modification. The bandgap of N-doped TiO2 photocatalyst shifts towards a higher wavelength, indicating a reduction in TiO2 bandgap. Utilizing N-doped TiO2 as an active photocatalyst, up to 66% methylene blue has been successfully degraded. The enhanced photodegradation of N-doped TiO2 film is mainly attributed to the presence of {101} and {111} facets, facilitating efficient carrier separation and prolonging the lifetime of photogenerated carriers, thereby improving its photocatalytic potential.

Summary: This study introduces a nanoetching technology to improve the photoelectrochemical (PEC) performance by exposing a large number of high-energy (101) crystal facets on rutile TiO2 nanorod films. The nanoetching technology significantly enhances charge separation and transfer efficiency, leading to improved PEC performance. The mechanism behind the enhancement is attributed to the reduced energy barrier for oxygen evolution reaction (OER) by shortening the distance between HO* intermediates on the rutile (101) facet and neighboring O-b. Additionally, the driving force for spatial charge separation between (110) and (101) facets promotes charge separation. This work offers a versatile nanotechnology for enhancing PEC performance.

Summary: This study investigates the photocatalytic degradation of methylene blue using flowerlike rutile-phase TiO2 films synthesized by a hydrothermal method. The research reveals that various parameters such as catalyst morphology, oxygen vacancy/Ti3+ surface defects, pH of the methylene blue solution, and initial concentration of the dye influence the photocatalytic activity of the TiO2 film. The presence of oxygen vacancy/Ti3+ surface defects is found to enhance the photocatalytic activity by acting as an electron trap.

Summary: (Nb0.5Ga0.5)(x)Ti1-xO2 single crystals with different doping amounts were prepared by Verneuil method. The crystals showed varying dielectric performance, with the best dielectric properties achieved at a doping amount of 0.5%. The colossal permittivity properties were attributed to EPDD polarization, and higher doping concentrations led to slight increases in dielectric loss. The results highlight the significance of TiO2 crystal materials with lower dielectric loss for the development of dielectric materials.

Summary: This study systematically investigated the mechanisms and kinetics of the aqueous-phase reactions of 1-butanol/1-decanol and their roles in the formation of organosulfate (OSA) nanoparticles. It was found that the reactions start from protonation of hydroxyl groups followed by esterification or oligomerization reactions, leading to the formation of OSA nanoparticles. Short-chain alcohols contribute more to the formation of OSA nanoparticles compared to long-chain alcohols. Additionally, long-chain alcohols participate in nanoparticle growth through esterification.

Summary: Inactivation of bioaerosols is crucial in preventing the spread of microbial pathogens in the air. Traditional photocatalytic inactivation processes are time-consuming and generate insufficient reactive oxygen species (ROSs) to irreversibly inactivate bacteria. A new photocatalytic ozonation (PCO) system was developed in this study, utilizing NiFeOOH nanosheets on nickel foam and trace concentration of ozone. The PCO system demonstrated a remarkable inactivation efficiency of 99.99% within a short retention time of 8.07 s, with no bacteria surviving after 24 h cultivation. This novel PCO system offers a more efficient method for bioaerosol inactivation and reduces the risk of exposure.

Summary: In this study, the structural, opto-electronic, and photocatalytic properties of GeC-MX2 (M = Mo, W, X = S, Se) van der Waals heterostructures for photocatalysis were systematically investigated using first-principles computations. The results showed that the GeC-MX2 heterostructures could absorb visible light and allow for continuous separation of photogenerated electron-hole pairs. The induced electric field at the interface between the GeC and MX2 monolayers was essential for preventing the recombination of photogenerated charges. Additionally, the band-edge locations suggested that GeC-MX2 heterostructures could be utilized as a photocatalyst for water splitting. Overall, the opto-electronic properties of these novel GeC-MX2 heterostructures made them suitable for future photocatalysis applications.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
