Diatomite is mined in Phu Yen province, Vietnam and the Fe2O3-diatomite materials are synthesized by a simple process for the photo-Fenton reaction of rhodamine B (RhB) degradation. The pure diatomite and Fe2O3-diatomite materials have large pore structures representing the high adsorption ability and efficient photocatalysis. Characterizations of diatomite-Fe2O3 materials were determined by X-ray diffraction (XRD), FT-IR analysis, field emission scanning electron microscopy (FE-SEM) images, dynamic light scattering (DLS), and inductively coupled plasma mass spectrometry (ICP-MS) analysis. The catalytic activity of the Fe2O3-diatomite materials was evaluated by the degradation of the ...
