Abstract Ag-La-CaTiO 3 was used in place of sacrificial agents to assess the influence operational factors on hydrogen generation a photocatalytic water splitting system. After being synthesized, physicochemical features this substance were accurately described. Several characterization techniques including UV–Vis spectroscopy, FTIR, XRD, XPS, EDX, SEM, TGA, DRS and BET applied study prepared photocatalyst. shows band visible wavelength between 400 800 nm at < 560 compared main CaTiO 350 nm. Ag 4d5s electrons transition conduction (CB), which is responsible for absorption ~ (> 2.21 eV). The effects catalyst concentration, light intensity, beginning solution pH H 2 rate may all be evaluated simultaneously using experimental design procedures. Up maximum threshold, where drop gas evolution occurs, it confirmed that increase dose positively affects system productivity. initial plays crucial role production, = 4 10 are optimum with higher yield production. highest total production rate, 6246.09 μmol, obtained concentration 700 mg equal under 1200 W Vis lamp h.

Facet-Dependent Phosphate Adsorption of CeO₂

Industrial & Engineering Chemistry Research, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

Cerium-based adsorbents are effective for the removal of phosphate from water, with reactivity cerium dioxide (CeO2) being highly dependent on exposed crystal facets. However, molecular-level interactions that control facet-dependent toward adsorption remain elusive. In this study, we synthesized CeO2 nanostructures distinct morphologies─rods (CeO2-R), octahedrons (CeO2-O), and cubes (CeO2-C)─that predominantly expose (110), (111), (100) facets, respectively. Phosphate various facets was systematically investigated through a series batch experiments, complemented by Fourier transform infrared (FTIR) spectroscopy density functional theory (DFT) calculations. The follows second-order kinetics aligns Langmuir isotherm model. This process is facilitated formation inner-sphere complexes between Ce–OH groups surface ions. performance significantly influenced geometric configuration normalized capacity to area following trend CeO2-R > CeO2-C CeO2-O. These results may have strong implications prediction fate contaminants at solid–liquid interface optimization advanced adsorbent materials water treatment applications.
