Reham Dabboura Yes, neodymium (Nd) doping into titanium dioxide (TiO2) is possible. Neodymium atoms can be incorporated into the TiO2 lattice, even though their atomic diameters are larger than those of titanium and oxygen. This process can lead to interesting material properties, such as improved photocatalytic activity and altered electronic band structures.

Nd forms Nd(OH)4, just like Ti(OH)4. Therefore, the formation of mixed hydroxides is possible. This confirms the existence of TiO2 in the monasite sand mineral with Nd.
