Optimum Sample

A magnetic photocatalyst [Formula: see text]-Bi2O3/Mn[Formula: see text]Zn[Formula: see text]Fe2O4 (Bi2O3/MZF) was fabricated by hydrothermal and calcination method, and characterized by XRD, FTIR, XPS and SEM, BET and VSM. The photocatalytic efficiency was measured by the degradation experiment of Rhodamine B (RhB). The degradation rate of the optimum sample Bi2O3/MZF (10 wt.%) could reach 96.8% after 3 h under visible light, and was improved significantly compared with pure [Formula: see text]-Bi2O3 due to the larger pore size (11.76 nm) and specific surface area (17.87 m2 ⋅ g[Formula: see text]. Meanwhile, the Bi2O3/MZF (10 wt.%) could be recovered under the external magnetic field due to its high magnetization saturation (9.22 emu ⋅ g[Formula: see text]. After reusing three times, the Bi2O3/MZF could still maintain the excellent photocatalytic activity and structural stability.

ZnO nanowhiskers were used for photodecomposition of methylene blue in aqueous solution under UV irradiation. The rate of methylene blue degradation increased linearly with time of UV irradiation. 54% of degradation rate was observed when the ZnO nanowhiskers were used as photocatalysts for methylene blue degradation for 80 min under UV irradiation. The decoration of p-type NiO nanoparticles on n-type ZnO nanowhiskers significantly enhanced photocatalytic activity and reached 72% degradation rate of methylene blue by using the same method. NiO-decorated ZnO was recycled for second test and shows 66% degradation from maximal peak of methylene blue within the same period. The increment of photocatalytic activity of NiO-decorated ZnO nanowhiskers was explained by the extension of the electron depletion layer due to the formation of nanoscale p-n junctions between p-type NiO and n-type ZnO. Hence, these products provide new alternative proficient photocatalysts for wastewater treatment.

This study combines the template method and sol-gel method, prepares TiO2 photocatalytic materials with the cotton, leaves and towel gourd as the template, and then makes degradation of phenol in ultraviolet light with the prepared TiO2 photocatalysts. The results show that all the photocatalyst prepared with three kinds of templates have high photocatalytic activity, among which, the catalytic performance of cotton is better, leaves secondly, and towel gourd’s relatively poor. With cotton as templates for the preparation of TiO2 under UV irradiation for 6h, the degradation rate was 80%, leaves as template for the preparation of TiO2 under UV irradiation for 6h, the degradation rate was 63%, and with towel gourd as template for the preparation of TiO2 under UV irradiation for 6h, the degradation rate was 52%.
