Summary: Zinc oxide nanoparticles were successfully synthesized using glycine nitrate solution combustion synthesis. The synthesized nanoparticles exhibited a pure hexagonal wurtzite-like structure of ZnO. They showed effective visible light catalytic activity in the degradation of methylene blue dye, degrading 98% of the dye in 120 minutes with 0.1 g/L of catalyst loading. Photoluminescence studies suggested that the enhanced photocatalytic activity may be attributed to the presence of singly ionized oxygen vacancy or intrinsic defects.

Summary: In this study, BiVO4@α-Fe2O3-CF (BiFeC) based Z-scheme photocatalysts were hydrothermally fabricated. The as-prepared catalysts were well characterized using various analytical tools. Among the prepared samples, BiFeC-1 exhibited excellent photocatalytic activity towards the degradation of methylene blue (MB) (97% in 2h) and tetracycline (TC) (89% in 1h) compared to their bare counterparts (45% and 42% for BiVO4, 29% and 18% for α-Fe2O3, respectively). The improved photocatalytic performance of Z scheme BiFeC-1 can be attributed to an increased specific surface area, enhanced light harvesting ability, and improved redox properties, leading to the inhibition of charge carrier recombination. Additionally, the optimal BiFeC-1 demonstrated high photo-stability and reusability based on consecutive recycle experiments over five times for both MB and TC.

Summary: This study presents the synthesis of ultrathin copper oxide nanosheets (CuO-NS) using a versatile foam-surfactant dual template (FSDT) approach and demonstrates their electro-oxidation and sensing performance for hydrazine. The CuO-NS were prepared by chemical deposition of dissolved copper ions in a hexagonal surfactant template using hydrogen foam generated by a reducing agent. The CuO-NS exhibited superior oxidation performance compared to bare-CuO, with a high hydrazine sensitivity, low detection limit and a linear concentration range. Additionally, CuO-NS showed potential for practical hydrazine detection in water samples with good recovery, and the FSDT approach can be used to synthesize a wide range of nanomaterials for boosting electrochemical catalytic reactions.

Summary: This study synthesized noble metal-doped BiOBr microspheres using a solvothermal method and tested their degradation performance of phenol under visible light. The results showed that the Pd-doped BiOBr material exhibited enhanced degradation efficacy, about 4 times higher than pure BiOBr. This improvement was attributed to enhanced photon absorption, reduced recombination rate, and increased surface area facilitated by surface plasmon resonance. Additionally, the Pd-doped BiOBr sample showed good reusability and stability after 3 cycles of operation. A plausible charge transfer mechanism for phenol degradation over the Pd-doped BiOBr sample was also revealed. These findings highlight the potential application of noble metal-doped semiconductor metal oxides as visible light materials for the elimination of colorless toxins from untreated wastewater.

Summary: Photoelectrochemical (PEC) solar water splitting using semiconductor electrodes is a promising method for converting solar energy into hydrogen fuel. In this study, strontium titanium oxynitride (STON) with anion vacancies was prepared via solid phase synthesis and used as a photoelectrode for alkaline water oxidation. The PEC efficiency was improved by depositing a cobalt-phosphate (CoPi)-based co-catalyst on the surface of the STON electrode. The enhanced oxygen evolution kinetics and reduced surface recombination of photogenerated carriers contribute to the observed PEC enrichment. Additionally, the CoPi modification of perovskite-type oxynitrides presents a new avenue for developing efficient and stable photoanodes in solar-assisted water-splitting reactions.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. 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.
