Article Abstract
Iron oxyhydroxide [FeO(OH)] is a promising photocatalyst owing to its simple synthesis at mild temperatures and narrow band gap, which allows for the efficient harvesting of visible light. The selective production of FeO(OH) polymorphs and the modulation of their morphology by changing the iron salts, salt concentration, and additives have been widely reported. This study focuses on overcoming fast charge-carrier recombination by developing FeO(OH)-based heterostructure materials. The role of a chelating ligand (EDTA and citrate) in determining the polymorph type, morphology, and photocatalytic activity of FeO(OH) was studied. The findings revealed the additive produced of nanosized α-FeO(OH)/EDTA and layered γ-FeO(OH)/citrate with superior catalytic activities.

This study presents an eco-friendly approach for the green synthesis of manganese oxide nanoparticles (MnONPs) using () (einkorn wheat) seed extract as a reducing and stabilizing agent. The synthesized MnONPs were characterized by UV-Vis, XRD, FTIR, SEM-EDX, BET, and zeta potential analyses, which confirmed their crystalline nature, spherical morphology, and mesoporous structure with a surface area of 41.50 m/g.

The study introduces a sustainable and eco-friendly approach to the first-time biosynthesis of zinc oxide (ZnO) nanoparticles using Schizophyllum commune (S. commune), a wood-rotting fungus that is well known for its superior lignocellulose biodegradation ability. The unique enzymatic machinery and metabolites produced during the lignocellulose breakdown not only provide a natural reducing and stabilizing environment but also facilitate the controlled synthesis of ZnO nanoparticles without the need for hazardous chemicals, high-energy input, or complex reaction conditions.

Photocatalytic technology has garnered considerable attention in wastewater treatment, but its application to complex wastewater remains challenged by particle aggregation and the difficulty of separating the catalyst from water. In this study, the heterojunction composite catalyst ZnS@BiS and halloysite nanotubes (HNTs) are immobilized onto a sponge substrate to enhance photocatalytic performance. SEM, XRD, XPS, FTIR, and UV-Vis analyses are conducted to characterize the morphology and evaluate the organic degradation performance of PPG/HNTs/ZnS@BiS.

The development of environmentally friendly and highly efficient materials is critical for next-generation antibacterial and optoelectronic applications. In this study, we present the successful synthesis of a novel lead-free perovskite, KCsSnICl, via a rapid and scalable chemical bath deposition method at 150 °C for just 5 min. The resulting film features well-defined orthorhombic, pyramid-like crystals with uniform grain sizes (800-1000 nm) and a compact, pinhole-free morphology.

This study demonstrates the photocatalytic degradation efficiency of doped NiZnO and co-doped CdNiZnO NPs. Initially, ZnO NPs with a unique mesoporous ellipsoidal morphology were synthesized by simple precipitation and calcination. Powder X-ray diffraction revealed the formation of a hexagonal phase of the wurtzite structure.
