Green synthesis of BaSO4@SiO2 core–shell and BaSO4@ZIF-8 nanocomposite and assessment of their cytotoxicity effects and photocatalytic performance

FTIR

FTIR spectroscopy was employed to elucidate the chemical bands generated during the synthesis of BaSO₄@SiO₂ Fig. 3a and BaSO₄@ZIF-8 Fig. 3b within the spectral range of 400–4000 cm⁻¹. As delineated in the extant literature, four…
