Recent advances in making nano-sized TiO₂visible-light active through rare-earth metal doping

Nb-Doped TiO2 Nanofibers for Lithium Ion Batteries

“…26 Doping with aliovalent ions is also a facile strategy to modify the electronic properties of electrospun titanium oxide. 17,18,[27][28][29][30] Nevertheless, only few papers report this procedure for application of the materials in LIB. 31 This is astonishing as, for example, Wang et al show that the conductivity, which is the crucial parameter for high performance cycling, can be raised two orders of magnitude by doping mesoporous TiO 2 with Nb.…”

Synthesis of Erbia Decorated Titania Nanowires Array Using Glancing Angle Deposition Technique

“…1 [32][33][34]. The diffraction from (400) has also observed which is due to Si substrate [7]. Therefore, the XRD pattern reveals the highly polycrystalline nature of the fabricated sample after annealing at the temperature of 800 o C. …”

“…It has been reported that the impurity doping in the high band gap 1D TiO 2 semiconductor can reduce the band gap within the threshold limit [6]. TiO 2 is a prominent candidate as host material of Ln 3+ because of its chemical, thermal and mechanical properties [7]. The doping of rare earth oxides in the 1D TiO 2 semiconductor reduces its band gap [8,9].…”

Synthesis and Catalytic Applications of Non-Metal Doped Mesoporous Titania

“…UV light corresponds to only 4%-5% of the whole solar spectrum, while visible light constitutes 40% [24]. To reduce the intrinsic band gap of TiO 2 , several strategies have been tested including the incorporation of either metallic (e.g., Fe and Ni) or non-metallic (e.g., C, F, N, S, P, and B) atoms into the lattice of TiO 2 host materials [9,15,[25][26][27]. Metal doping has shown controversial photocatalytic activity results at both UV and visible wavelengths [28][29][30][31].…”
