Photocatalytic Activity of Nanosized TiO2 Enhanced by co-doping with Fe3+ and Nd3+ Ions Zhao Zhuo1,Fu Pingfeng1,Wang Jingxin3 (1.Department of Environmental Science, College of Arts & Science.... The metallic ion doped TiO2 was thoroughly characterized with XRD and UV-vis, and the photocatalytic activity was evaluated by degrading methylene blue (MB) solution. The results indicated that TiO2......
on the stability of copper species. These diagrams show the zone that limits the predominance of soluble species and the existence of insoluble Cu(II). Cu(II) exists mainly in the form of copper aquocomplexes... leads to widening of stability region of Cu(OH)1.5Cl0.5 and CuO, and makes the solubility of Cu(II) decrease. Fig.3(c) shows the predominance existence diagram of -lg m[NH3+NH4+] versus pH for 0.2......
