“…In another notable work, Wang et al [43] synthesized Y and Eu co-doped TiO 2 nanoparticles through a sol-gel procedure and investigated their photocatalytic activities by monitoring the degradation of MB under UV light irradiation. Very recently, the high photocatalytic efficiency of Nd, Nd-Y, and Nd-Sm co-doped TiO 2 nanoparticle photocatalysts was confirmed by implementing the decomposition of azo dye Orange G [44]. The stability and recyclability of all photocatalysts used in this study were investigated, and it was found that the best stability was shown by Nd-Y co-doped TiO 2 nanoparticles.…”

In this presented work, pure and holmium, niobium, and holmium-niobium co-doped titanium dioxide nanopowders were synthesized by the sol-gel method. Their morphological, structural, optical, and photocatalytic properties were analyzed by scanning electron microscopy, X-ray diffraction, and UV-visible spectrophotometer. The photocatalytic activities of the synthesized nanopowders were examined using ultraviolet light. The results have shown that doping both with a single (holmium, niobium) or two types of elements (holmium-niobium) have significantly changed the properties of titanium dioxide. It was concluded that, compared with others, the holmium-niobium co-doped sample has the smallest crystal size. Other values, such as forbidden band gap and kinetic constants, are in the range of the data obtained for single-element doping.

“…Guetni et al found that doping TiO 2 with Nd allows the material to absorb radiation in the visible range by creating Nd-4f impurity states. The co-doping with Y further increases the Azo dye orange G degradation under a wavelength range of 300–800 nm due to the synergetic effect of intragap levels [ 63 ].…”

Heterogeneous photocatalysts have garnered extensive attention as a sustainable way for environmental remediation and energy storage process. Water splitting, solar energy conversion, and pollutant degradation are examples of nowadays applications where semiconductor-based photocatalysts represent a potentially disruptive technology. The exploitation of solar radiation for photocatalysis could generate a strong impact by decreasing the energy demand and simultaneously mitigating the impact of anthropogenic pollutants. However, most of the actual photocatalysts work only on energy radiation in the Near-UV region (<400 nm), and the studies and development of new photocatalysts with high efficiency in the visible range of the spectrum are required. In this regard, hybrid organic/inorganic photocatalysts have emerged as highly potential materials to drastically improve visible photocatalytic efficiency. In this review, we will analyze the state-of-art and the developments of hybrid photocatalysts for energy storage and energy conversion process as well as their application in pollutant degradation and water treatments.
