Preparation of TiO2/α-Fe2O3@SiO2 Nanorod Heterostructures and Their Applications for Efficient Photodegradation of Methylene Blue

Crystals, Год журнала: 2025, Номер 15(3), С. 277 - 277

Опубликована: Март 17, 2025

A facile solvo-hydrothermal method was used to synthesize sub-100 nm diameter TiO2/α-Fe2O3@SiO2 nanorods (TiO2/HNRs@SiO2). Thermal annealing of TiO2/HNRs@SiO2 activated the photosensitizing crystalline TiO2 domains containing mixed anatase and rutile phases. The photocatalytic degradation methylene blue (MB), conducted using thermally annealed photocatalysts, successfully demonstrated with ~95% MB removal efficiency under mild conditions pH = ~7 room temperature ~150 min solar irradiation. enhanced attributed rapid adsorption onto surface via favorable electrostatic interactions synergistic integration α-Fe2O3 into nanorod heterostructures bandgaps 1.99–2.03 eV, allowing them absorb visible light for efficient decomposition. This study provides insights designing photocatalysts improved selectivity sustainable water treatment environmental remediation.

Assessment of the Effects of ZnO and CuO Engineered Nanoparticles on Physicochemical Properties of Volcanic Ash Soil and Phosphorus Availability

Environments, Год журнала: 2024, Номер 11(9), С. 208 - 208

The presence of engineered nanoparticles (ENPs) in soil systems can modify their properties and the availability nutrients. This study evaluated effect 1% CuO or ZnO ENPs on physicochemical phosphorus (P) adsorption–desorption processes a volcanic ash (Lautaro; LAU). dynamics P were conducted through kinetic isotherm batch experiments. results showed that LAU with increased pHH2O (from 5.67 to 6.03 6.82, respectively), electrical conductivity 0.119 0.143 0.150 dS m−1, Zn (597.7 times higher for relation without ENPs), Cu (41.8 ENPs). Moreover, decreased Brunauer, Emmett, Teller specific surface area. adsorption studies fitted well Elovich model (r2 ≥ 0.923), which indicated chemiadsorption mechanism, whereas isotherms described by Langmuir–Freundlich 0.939). desorption percentage was > + CuO–ENPs ZnO–ENPs, demonstrating an stability P–soil binding ENPs. Co–existing NO3−, SeO42−, SO42− anions did not generate steric hindrance between binding. Finally, both could alter quality due changes decrease soils.

The global serious pollution situation urgently needs green, efficient, and sustainable development methods to achieve heavy metal control. photocatalytic properties of anatase are sufficient control by providing photoelectrons harmful metals. However, since natural particles tend agglomerate deactivate in water, most studies have been conducted prepare TiO2–biochar nanocomposites using chemical synthesis methods. In the present study, we utilized pyrolytic sintering load onto biochar obtain anatase–biochar (TBC) composites. Characterization tests, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), showed that was uniformly partitioned into surface pores without destroying lattice structure. Due its properties, TBC degraded Cr (VI) 99.63% under light conditions. This is 1.58 times higher than dark condition. Zeta potential positively charged acidic charge attraction between chromium salt involved efficient degradation (VI). Different sacrificial agents well gas purge experiments demonstrated (e−) superoxide radicals (O2−) dominated has characteristics high efficiency, stability, sustainability. may provide a new idea for preparation materials realization environmental protection through
