Doped-metal oxide nanoparticles for use as photocatalysts

Nano-sized doped-metal oxides such as Fe-doped TiO2, WO3-doped ZnO and Fe-doped CeO2were synthesized by the modified sol-gel/impregnation, flame spray pyrolysis and homogeneous precipitation/impregnation methods respectively. The crystalline phase, particles size, and crystallinity of nano-sized pow...
