A series of Au/alpha-Fe2O3 catalysts promoted with ZrO2 and Nb2O5 were prepared by parallel co-precipitation method. Detailed characterizations were conducted by techniques including UV-Vis-DRS, XPS, TEM and XRF. Results indicated that the enrichment of Au, ZrO2 and Nb2O5 on the surface induced by the strong interaction between ZrO2 and Nb2O5 kept the(More)
K4Nb6O17 photocatalyst was successfully synthesized by low-temperature hydrothermal method with layer structure. Considering that a large number of hydroxyl (Nb-OH) and oxygen species (Nb==O, Nb--O-) exist on the surface of K4Nb6O17 synthesized by hydrothermal method, Ag(en)2+ precursors were employed to synthesize Ag/K4Nb6O17 heterostructure(More)
In the present paper, ordered mesoporous silica (KIT-6) as support, nanosized TiO2 into KIT-6 was synthesized by titanium tetraisopropoxide hydrolysis. Then silver was loaded by deposition-precipitation method. Ag-TiO2/KIT-6 composite nanosized photocatalyst was firstly synthesized and a series of correlated catalysts were synthesized by the same(More)
The title complexes were synthesized via reaction of iron nitrate, cobalt acetate and copper acetate with the didentate O,N-donor Schiff bases in methanol solution. The electronic and infrared spectra of these complexes were measured and the major IR bands were assigned.
