“…As demonstrated in Figure 1, the LC Y 2 O 3 -loaded NPs exhibited broad UV absorption with enhanced intensity at 288 nm. Similar results were reported for rare earth oxides [61] and organic semiconductor-coated silver particles [62], where such effect was attributed to absorption-induced scattering. The presence of multifunctional groups in the L. camara leaf extract and green synthesized LC Y 2 O 3 NPs were investigated using FTIR.…”

Due to their appropriate physicochemical properties, nanoparticles are used in nanomedicine to develop drug delivery systems for anticancer therapy. In biomedical applications, metal oxide nanoparticles are used as powerful and flexible multipurpose agents. This work described a green synthesis of Y2O3 nanoparticles (NPs) using the sol-gel technique with the use of aqueous leaf extracts of Lantana camara L (LC). These nanoparticles were characterized with the aid of different methods, including UV, X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), transmitted electron microscopy (TEM), and photocatalytic degradation. Y2O3 nanoparticles showed excellent antibacterial activity against Gram-positive Bacillus subtilis and Gram-negative Escherichia coli with a 10 to 15 mm inhibitory zone. Green Y2O3 NPs were released with a 4 h lag time and 80% sustained release rate, indicating that they could be used in drug delivery. In addition, the bioavailability of green Y2O3 NPs was investigated using cell viability in cervical cancer cell lines. These green-synthesized Y2O3 NPs demonstrated photocatalytic degradation, antibacterial, and anticancer properties.

“…Another advantage compared with recent works which synthesized Y 2 O 3 through the sol-gel method is the reduction of the time for 1 h of calcination in this present work. Several works report the Y 2 O 3 formation with heat treatment above 2 h [26][27][28][29]. The time and temperature reduction for oxide crystallization using a PVA solution is discussed in the literature [18].…”

The effect of synthesis parameters on the microstructural behavior and morphology during the yttrium oxide (Y 2 O 3 ) formation is reported. Y 2 O 3 crystals were produced by a modified sol-gel route assisted by polyvinyl alcohol solution varying the calcination temperature and solution pH. The crystalline phase formation was investigated using X-ray powder diffraction combined with the Rietveld refinement method. The microstructural properties were analyzed by using the Williamson-Hall formalism. The calcination temperature followed the thermal events observed in the differential thermal analysis combined with the thermogravimetric analysis of the precursor xerogel. It was seen that the combination of PVA and pH variation can be used to minimize the calcination time and temperature. The morphological analysis showed samples with different sizes and appearances depending on pH and calcination temperature. Therefore, it was shown that the parameters in the synthesis process can be used to tailor the properties of Y 2 O 3 , such as crystallite size, degree of structural ordering, and morphology, and consequently, improve the desired application.

“…Based on present literature, large number of chemical methods like sol-gel [87][88][89], microemulsion or reverse micelles [90][91][92], citrate precursor method [93][94][95], co-precipitation [96,97], solvothermal synthesis [98,99], hydrothermal method [100][101][102] and other methods have been employed in the synthesis metal oxide nanoparticles [103,104]. In figure 4, we have summarized all the methods which have been used for the synthesis of rare earth doped metal oxide nanoparticles to the best of our knowledge.…”

Rare earth doped metal oxide nanoparticles for photocatalysis: a perspective

et al. 2022

Metal oxides are well-known materials that have been considered as the prominent photocatalysts. Photocatalysis is a promising way to address the environmental issues which arecaused by fossil fuel the combustion and industrial pollutants. Lots of efforts such as doping metal oxides with metals, non-metals or metals/non-metals have been made to enhance their photocatalytic activity. More specifically, in this review we have discussed detailed synthesis procedures of rare earth doped metal oxides performed in the past decades. The advantage of doping metal oxides with rare earth metals is that they readily combine with functional groups due to the 4f vacant orbitals. Moreover, doping rare earth metals causes absorbance shift to the visible region of the electromagnetic spectrum which results to show prominent photocatalysis in this region. The effect of rare earth doping on different parameters of metal oxides such as band gap and charge carrier recombination rate has been made in great details. In perspective section, we have given a brief description about how researchers can improve the photocatalytic efficiencies of different metal oxides in coming future. The strategies and outcomes outlined in this review are expected to stimulate the search for a whole new set of rare earth doped metal oxides for efficient photocatalytic applications.
