Experimental, predictive and RSM studies of H₂ production using Ag-La-CaTiO₃ for water-splitting under visible light.

ABSTRACT: Ag-La-CaTiO₃ was used in place of sacrificial agents to assess the influence of operational factors on hydrogen generation in a photocatalytic water splitting system. After being synthesized, the physicochemical features of this substance were accurately described. Several characterization techniques including UV-Vis spectroscopy, FTIR, XRD, XPS, EDX, SEM, TGA, DRS and BET were applied to study the prepared Ag-La-CaTiO₃ photocatalyst. Ag-La-CaTiO₃ shows a band in the visible wavelength between 400 and 800 nm at < 560 nm compared to the main CaTiO₃ band at 350 nm. Ag 4d5s electrons transition to the conduction band (CB), which is responsible for the absorption band at ~ 560 nm (> 2.21 eV). The effects of catalyst concentration, light intensity, an
