“…Until now, a great deal of work has been performed to design and produce different nanostructures containing noble metal (Pt, Pd, Au, Ag) cores and CeO2 shells with outstanding optical and catalytic properties [6][7][8][9][10]. However, the synthetic protocols for the production of these NCs have become considerably more and more complicated as the control of NC's morphology and architecture becomes more precise, often requiring multiple steps and exotic techniques [7,11].…”

Well-defined colloidal Au@CeO2 hybrid nanocrystals (NCs) comprising different core/shell morphologies have been synthesized via a novel and simple one-pot aqueous approach. The method allows producing hybrid morphologies composed by an active and accessible Au core coated by a porous CeO2 shell with varying shell thickness and dimensionality by simply adjusting the Au 3+ /Ce 3+ precursor ratio. These hybrid NCs are highly monodisperse and welldispersed in water, showing intense surface plasmon resonance bands that offer unique opportunities for advanced material applications, such as plasmonics and catalysis.

“…This Au/CeO 2 catalyst demonstrates an enhanced activity in comparison to conventionally prepared systems, this behavior being assigned to the variation of the nucleation velocity during the catalyst preparation. Very recently, a novel method based on the photo-thermal effect generated from localized surface gold plasmon resonance (LSPR) has been proposed for preparing Au/CeO 2 core-shell structures [107]. The method benefits from the heat generated by LSPR on Au nanoparticles, which induces the polymerization reaction of the ceria precursor sol and results in ceria formation just on the Au nanoparticles surface.…”

Abstract:In this comprehensive review, the main aspects of using Au/CeO 2 catalysts in oxidation reactions are considered. The influence of the preparation methods and synthetic parameters, as well as the characteristics of the ceria support (presence of doping cations, oxygen vacancies concentration, surface area, redox properties, etc.) in the dispersion and chemical state of gold are revised. The proposed review provides a detailed analysis of the literature data concerning the state of the art and the applications of gold-ceria systems in oxidation reactions.

“…Therefore, only the light with a short wavelength can offer sufficient energy to excite the electrons in the valence band, forming photogenerated carriers. Some researchers have reported the formation of heat due to the localized surface plasmon resonance effect of Au [45][46][47][48]. In order to further investigate the effect of LOM photocatalytic degradation in this study, experiments at different temperatures were also conducted.…”

With the fast development of intensive poultry and aquaculture, the consumption of antibiotics has ever been increasing. Absorbed or metabolized antibiotics usually enter the water environment in the form of active drugs and metabolites, which can enhance the resistance of pathogenic microorganisms and even cause serious water pollution. Considering the bacteriostatic activity of antibiotics, the main biological method used to treat organic waste water has limited efficiency. Herein, we prepared Au/TiO2 for the efficient photocatalytic degradation of lomefloxacin (LOM) antibiotic wastewater. Based on the characteristics of prepared Au/TiO2, the short–wavelength light can be converted into photogenerated carriers with TiO2 support and the long–wavelength light can be converted into heat, likely due to the localized surface plasmon resonance effect of Au, synergistically promoting the LOM degradation. This study not only demonstrates that Au/TiO2 is an efficient photocatalyst for LOM degradation, but also further indicates the effectiveness of photocatalytic technology in the treatment of antibiotic wastewater.
