Photocatalytic degradation of dyes by AgBr/Ag_3PO_4 and the ecotoxicities of their degraded products 磷酸银溴化银光催化降解一步合成生态毒性通过调节Na_3PO_4溶液中H_3PO_4的含量制得沉淀剂,AgNO_3与此沉淀剂反应制得Ag_3PO_4粉末.当沉淀剂pH=6时,所制得的Ag_3PO_4粉末表现出最高的光催化降解甲基蓝...
In this paper, carbon nanotube (CNT) and titania nanoparticle (n-TiO2) were used to degrade dyes using single (UV/CNT/H2O2 and UV/n-TiO2/H2O2) and binary catalyst (UV/CNT/n-TiO2 and UV/CNT/n-TiO2/H2O
This MOF material, which is both thermally and chemically (basic and acidic) stable, exhibits semi-conductivity and high photocatalytic activity towards degradation of dyes in the presence of H2O2. Its catalytic performance is superior to that of reported MOFs and comparable to some composites, ...

Parameters effecting the photocatalytic degradation Photocatalytic degradation of dyes are influenced by several parameters, such as pH, initial concentration of dyes, photocatalyst particle size and its concentration, reaction temperature, light intensity and the presence of electron acceptors. ...
Photocatalytic Degradation of Water-Soluble Azo Dyes by LaFeO3 and YFeO3 Perovskite-type oxides LaFeO3 and YFeO3 were prepared by the citrate method. The samples were characterized by X-ray diffraction (XRD), transmission electr... XJ Wang,HY Shen,HY Tian,... - 《Advanced Materials Research...
The photocatalytic decolorization of municipal waste-water contaminated with textile dyes was studied using a batch reactor. Degussa P25 titanium dioxide was used as the photocatalyst and proved to be effective for dye degradation when irradiated with UV light in the presence of air. In addition to...
This was attributed to the metals being in ionic state in metal substituted TiO synthesized by combustion method, and zero state of metal in impregnated catalysts as evidenced by XPS study. The degradation of dyes was also investigated in solar exposure. The photoactivity of the combustion ...
Herein we reported the preparation and potential application of SiO2 NPs (SiO2 NPs) for the photocatalytic degradation of methyl red dye in aqueous medium. These are synthesized from rice husk ash (RHA) which was collected from rice mill near Shankaraghatta (Shimoga, Karnataka). Silica was pres...
