High quality silver (Ag) decorated CeO2 nanoparticles were prepared by a facile one-step chemical method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), High resolution transmission electron microscopy (HR-TEM), fourier transform infrared spectrometer (FT-IR), electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), UV–Visible absorption (UV–Vis), photoluminescence (PL) and thermogravimetric analysis. The decoration of Ag on CeO2 surface was confirmed by XRD, EPR and HR-TEM analysis. Harmful textile pollutant Rose Bengal dye was degraded under sunlight using the novel Ag decorated CeO2 catalyst. It was found that great enhancement of the degradation efficiency for Ag/CeO2 compared to pure CeO2, it can be ascribed mainly due to decrease in its band gap and charge carrier recombination rate. The Ag/CeO2 sample exhibited an efficient photocatalytic characteristic for degrading RB under visible light irradiation with a high degradation rate of 96% after 3 h. With the help of various characterizations, a possible degradation mechanism has been proposed which shows the effect of generation of oxygen vacancies owing to the decoration of Ag on the CeO2 surface.

“…Shifting of peaks to higher 2θ reflects that crystallite size is decreasing with increasing dopant amount, due to smaller ionic radii of dopant Mo 4+ /Mo 6+ (0.68 Å/0.62 Å) (60,64). This smaller radii will alter the local symmetry by doping heteroatoms (65,66). Chemical composition and identification of functional group of Mo-doped La 2 O 3 were measured using FTIR analysis as represented in figure 4(b).…”

“…Consequently, the CeO 2 -Zr-1 electrode showed best specific capacitance as high as 905.4 F g À 1 (448.1 C g À 1 ) in 2 m KOH electrolyte, and the CeO 2 -Zr-1//AC asymmetric supercapacitor device assembled by this electrode and AC can still maintain 96.4 % of capacity retention over 6000 cycles. Additionally, other heterogeneous atoms or ions (e. g., Ni, [39,56] Co, [114] Ag, [115,116] etc.) have also been used as dopants to modify the electrochemical properties of CeO 2 .…”

Supercapacitors (SCs) can effectively alleviate problems such as energy shortage and serious greenhouse effect. The properties of electrode materials directly affect the performance of SCs. Rare earth (RE) is known as “modern industrial vitamins”, and their functional materials have been listed as key strategic materials. In the past few years, the number of scientific reports on RE‐based nanomaterials for SCs has increased rapidly, confirming that adding RE elements or compounds to the host electrode materials with various nanostructured morphologies can greatly enhance their electrochemical performance. Although RE‐based nanomaterials have made rapid progress in SCs, there are very few works providing a comprehensive survey of this field. In view of this, a comprehensive overview of RE‐based nanomaterials for SCs is provided here, including the preparation methods, nanostructure engineering, compounds, and composites, along with their capacitance performances. The structure–activity relationships are discussed and highlighted. Meanwhile, the future challenges and perspectives are also pointed out. This Review can not only provide guidance for the further development of SCs but also arouse great interest in RE‐based nanomaterials in other research fields such as electrocatalysis, photovoltaic cells, and lithium batteries.
