Summary: In this study, Mn3O4 nanoparticles were synthesized using the hydrothermal method and characterized for their morphology, surfaces, crystalline structure, and photocatalytic activity. The results confirmed the crystalline structure of Mn3O4 with a tetragonal phase and revealed a mixed rod-like morphology and rough surface spherical particles. The synthesized Mn3O4 nanoparticles showed photocatalytic activity towards methylene blue in water under natural solar irradiation for long periods of time, without the need for adjusting the pH or introducing an oxidant into the reaction mixture. This study suggests that the prepared Mn3O4 nanostructures have promising applications as photocatalysts for the degradation of organic dyes in aqueous media.

Summary: ZnO nanostructures with different morphologies were successfully prepared by hydrothermal synthesis, and their properties were characterized by XRD, SEM, TEM, and PL. The results showed that the morphology of ZnO changed from particles and flowers to rods with an increase in the amount of added NaOH. The different morphological ZnO samples exhibited similar emissions and high photocatalytic activity.

Summary: In this study, TiO2/BiVO4 composite photocatalysts with heterojunction architectures were successfully synthesized by a facile hydrothermal method. The as-prepared catalysts were characterized using various techniques, and their photocatalytic performance was evaluated. The TiO2/BiVO4 composites exhibited enhanced photocatalytic activity compared to pure TiO2 and BiVO4, which can be attributed to the increased separation rate of photogenerated charge carriers.

Summary: ZnO hollow microspheres were successfully prepared using a sucrose-derived carbon template-assisted hydrothermal method. The microspheres showed a shell composed of aggregated ZnO nanoparticles and a hollow interior after decomposition of the sucrose-derived carbon core. Both ZnO hollow microspheres and ZnO nanoparticles exhibited excellent photocatalytic activity for rhodamine blue degradation under UV light, with the hollow microspheres showing 10% higher efficiency due to their nanoporous structure, higher surface area, and easy formation of ·OH radicals.

Summary: This review discusses the recent advances in the synthesis approaches, fundamental properties, and photocatalytic activity of Cu3N nanostructures. The study found that the synthesis conditions play a crucial role in the shape and size control of Cu3N. Cu3N nanostructures exhibit a narrow bandgap and excellent optical properties, and the presence of Cu and N vacancies on the surface of the nanoparticles contributes to their photocatalytic dye-degradation potential. Additionally, combining plasmonic nanoparticles with other photocatalysts enhances the efficiency of Cu3N.

Summary: TiO2 nanomaterials were synthesized through a sol-gel method using titanium butoxide as a precursor, Pluronic F127 as a template, toluene as a swelling agent, and acidic water or ethanol as reaction solvents. The synthesis medium influenced the phase composition of the solids, with ethanol promoting dispersed anatase particles and water leading to a rutile phase. The photocatalytic activity of the samples was tested by the photodegradation of Rhodamine B.

Summary: In this study, silver nanoparticles of two different sizes were prepared and compounded with semiconductor materials, demonstrating the photocatalytic enhancement of the system. It was found that the hydrogen yield was almost unaffected by the silver core diameter and the hydrogen production rate was essentially the same. Additionally, the rate of hydrogen precipitation in air for 9 months was significantly higher than previous studies, providing a new idea for the study of oxidation resistance and stability of photocatalysts.

Summary: This work investigated the structural, magnetic, and optical properties of pure CuO and double-substitution by Fe and Mn ions prepared by the hydrothermal method. Various techniques were used to study the structural and morphological properties. The results showed that the samples exhibited a polycrystalline monoclinic and nanosheet structure. The optical bandgap of the samples was obtained using UV-vis analysis. Vibrating-sample magnetometry revealed paramagnetic behavior in pure CuO and weak ferromagnetic behavior in the other samples.

Summary: Different properties like particle aspect ratio, density of electron traps, and morphology have been found to control the photocatalytic activity in various reaction systems, impacting water oxidation, methanol dehydrogenation, and oxidative decomposition of acetic acid. While morphology plays a significant role, symmetry does not seem to control the photocatalytic performance in this study.
