Porous LaFeO3 were synthesised by nanocasting method using mesoporous silica (SBA-15) as a hard template and used as a visible-light-driven photocatalyst. The as-synthesised LaFeO3 photocatalyst were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray Diffraction (XRD), N2 adsorption-desorption, and Ultraviolet–Visible Diffuse Reflectance Spectroscopy (UV-vis DRS). The photo-Fenton catalytic activities of porous LaFeO3 were investigated for the degradation of oily-containing wastewater. The results showed that porous LaFeO3 had better photo-Fenton catalytic activity under visilbe light irradiation than pure LaFeO3. The remarkable improvement photo-Fenton catalytic activity of porous LaFeO3 material could be attributed to the synergistic effect of adsorption and visible light photo-Fenton processes thanks to its porous structure.

Better Than

In this research, a series of novel MoSe2/SrTiO3 heterostructures were successfully prepared by a two-step hydrothermal method. The samples were characterized by XRD, UV-Vis, SEM, TEM, EDS and XPS. Results showed that the degradation of MO under UV is better than that under the visible light. And, MoSe2 loaded on SrTiO3 under UV irradiation demonstrated a higher catalytic activity. The degradation rate of methyl orange was 99.46% for MoSe2/SrTiO3 under the optimum loading weight (0.1[Formula: see text]wt.%). This is mainly because the combination of MoSe2 and SrTiO3 prevents electrons and holes recombination in SrTiO3 and [Formula: see text]O[Formula: see text] appears in the system. In general, MoSe2/SrTiO3 heterostructures have good environmental friendliness for photocatalytic degradation.
