Facile fabrication of alveolate Cu2−xSe microsheets as a new visible-light photocatalyst for discoloration of Rhodamine B

In this study, direct Z–scheme heterostructure CoWO4/g-C3N4 was synthesized by a facile hydrothermal method. The structural, morphological properties of the prepared samples were characterised by XRD, SEM, UV–Vis and PL measurements. The as-obtained heterostructure CoWO4/g-C3N4 exhibited enhanced photocatalytic activities toward the degradation of Rhodamine B under visible light irradiation with 92% Rhodamine B removal after 80 minutes irritation, which exceeded pristine g-C3N4 and CoWO4. The enhanced photocatalytic performance ascribed to interfacial contact between g-C3N4 and CoWO4, thus further inhibiting the recombination of photogenerated electron/hole pairs. It is anticipated that the construction of Z–scheme heterostructure CoWO4/g-C3N4 is an effective strategy to develop high-performance photocatalysts for the degradation of organic pollutants in water.

In this research, the magnetic visible light photocatalyst of Fe-TiO2@SiO2@Fe3O4 was synthesised using co-precipitation, sol-gel and hydrothermal method. The as-obtained material’s properties were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), diffuse reflectance spectra (UV- Vis), magnetic curve (VSM) and photoluminescence (PL). The catalytic activity of the materials under visible light was investigated for degradation of Rhodamine B pigment in water. The obtained results indicated that at the catalyst dose of 0.5 g/L, Fe-TiO2@SiO2@Fe3O4 with TiO2/SiO2@Fe3O4 (SF) ratio of 2:1 performed the highest efficiency of 99.3 % after 180 minutes under irritation. The enhanced photocatalytic performance of Rhodamine B under visible light could be ascribed to the reducing of band gap energy and decrease in the recombination rate of photogenerated electron/hole pairs. The catalytic activity after four times of recycling were 71,3 %.The material showed potential for further application in water treatment.
