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: Metal cocatalyst loading is a widely explored strategy to promote photocatalytic solar energy conversion. In this study, the distinct crystal facet effect of Pd cocatalyst in promoting selective hydrogenation of nitroarenes to amines of TiO2 photocatalyst was investigated. It was found that the Pd NO with {111} facet showed higher efficiency as a cocatalyst compared to the Pd NC with exposed {100} facet, due to its modulation of the Schottky barrier height and enrichment of surface reactants. The study highlights the importance of rational facet control of cocatalysts for enhancing photocatalytic hydrogenation 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: Exploring high efficiency S-scheme heterojunction photocatalysts with strong redox ability for removing volatile organic compounds from the air is of great interest and importance. However, how to predict and regulate the transport of photogenerated carriers in heterojunctions is a great challenge. In this study, density functional theory calculations were used to predict and synthesize a CdS quantum dots/InVO4 atomic-layer (110)/(110) facet S-scheme heterojunction with enhanced photocatalytic degradation rate for ethylene. Various experiments were conducted to validate the enhanced dissociation of photoexcited excitons and separation of free charge carriers, as well as the formation of S-scheme charge transfer pathways. The study also investigated the reaction mechanism of the photocatalytic C2H4 oxidation using in-situ electron paramagnetic resonance. This work provides insights into construction and optimization of semiconductor heterojunction photocatalysts for environmental remediation.

Summary: The study demonstrates the co-active effects of dual surface hydroxyl, OH of protic solvents on dye adsorption and electron injection efficiency in DSSCs. Various polar protic and aprotic solvents were used for dye extraction, and the presence of chlorophyll and functional groups was confirmed using UV-visible and FTIR spectroscopy. The overall performance of DSSCs was examined through I-V characteristics, revealing that protic solvents led to higher dye adsorption and photocurrent density due to their higher polarisability and enriched surface hydroxyl, OH. In contrast, aprotic solvents with limited and weak surface hydroxyl, OH resulted in reduced dye adsorption and photocurrent density. The highest photo-conversion efficiency of 0.25% was achieved using MeOH (a protic solvent).

Summary: Nanostructured SnS2 with enhanced edge sites is prepared and its impact on NO2 gas molecule detection at room temperature (RT) is investigated. The flower-like structure of SnS2 with exposed active sites provides more interaction channels for NO2 gas molecules. The crystal orientation along the (011) plane exhibits more active edge sites, thereby enhancing the sensing performance of the flower-like structure. The fabricated SnS2 gas sensor shows higher selectivity towards NO2 gas molecules. The flower-like structure of SnS2 provides higher stability and a 32.63% increased sensing response compared to the platelet-like structure. This result paves the way for the development of a practical room temperature NO2 gas sensor.

Summary: This research aims to improve the conductivity of a polymer blend with quasi solid state electrolyte by selecting target polymers, PMMA and PVdF, and analyzing their ratio, electrical impedance spectroscopy (EIS) and thermogravimetric analysis (TGA). The optimum conductivity value was found to be 3.44 x 10-6 Scm-1 at ambient temperature with a PMMA:PVdF ratio of 70:30. The analysis also showed that conductivity increases with temperature and has low activation energy (Ea). Additionally, the TGA demonstrated the stability of PBE up to 651 degrees C. Different concentrations of PBE were investigated to assess its stability and conductivity performance.

Summary: The utilization and performance of organic dicarbocyanine dye-conjugated molecules, specifically 1,1'-diethyl-4,4'-dicarbocyanine iodide (DDCI-4), as the sensing film in capacitive-type humidity sensors were studied. The structural and morphological characteristics of the sensing films, as well as the electrode gaps, were analyzed. Capacitive humidity sensors based on aluminum (Al)/DDCI-4/Al were fabricated using spin coating techniques, and the device with the smallest electrode gap (45+/-9.1 fF/%RH) showed the highest sensitivity. The study also investigated the hysteresis, response time, and recovery time of the sensors, which exhibited low values of 0.31%, 6 s, and 9 s, respectively. The excellent performance of the dye-based organic humidity sensors can be attributed to the electronic, ionic, and dipole polarizations of 1,1'-diethyl-4,4'-dicarbocyanine iodide.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
