“…After doping with Ce, Y, or B ions, the bactericidal activities of the Zn-TiO 2 materials are significantly improved at different calcination temperatures (Wang et al, 2017). In their next experiment, TiO 2 materials codoped with B and Ce ions (B/Ce-TiO 2 ) with different calcination temperatures were prepared, and all materials had a large ZOI, suggesting that the materials have excellent antimicrobial activities (Wang et al, 2018). Besides the antibacterial effect of Ce, B 2 O 3 was found in the materials and is dissolved in water to produce metabolic acid and boric acid.…”

Infectious diseases caused by bacteria remain a serious and global problem in human health. Herein, the discovery and application of antibiotics, which has attracted much attention in the past years, has helped to cure numerous infectious diseases and made huge contributions in the biomedical field. However, the widespread use of the broad-spectrum antibiotics has led to serious drug resistance for many human bacterial pathogens. In particular, bacterial drug resistance decreases therapeutic effects and leads to high mortality. Inspiringly, the introduction of nanomaterials in the biomedical field makes it possible to overcome the difficulty in bacterial drug resistance attributed to their unique antibacterial mechanism. Recently, a variety of metal-and metal oxide-based nanomaterials have been fully integrated in antibacterial applications and achieved excellent performances. Among them, cerium-and cerium oxide-based nanomaterials have received much attention worldwide. Remarkably, cerium oxide nanoparticles with lower toxicity act as effective antibacterial agents owing to their unique functional mechanism against pathogens through the reversible conversion of oxidation state between Ce(III) and Ce(IV). This article provides an overview of the state-of-the-art design and antibacterial applications of cerium-and cerium oxidebased materials. The first part discusses the underlying antibacterial mechanisms for cerium-and cerium oxide-based materials currently applied in biomedicine. The second part focuses on various antibacterial-related materials and their applications. In addition, the existing problems and future perspectives of the cerium-and cerium oxide-based materials make up the third part of this review. This paper could provide the possible mechanisms for antibacterial activities, various designs of cerium-and cerium oxide-based materials, and related antibacterial properties.

“…The peaks due to the Ce 3d 3/2 level for Ce 3+ ions are found at 882.7 and 896.9 eV, whereas, for the Ce 4+ state, a peak at 888.1 eV is formed. 31,32 At the same time, the peak owing to the Ce 3d 5/2 level for Ce 4+ cations has appeared at 902 and 916.9 eV along with a peak at 907.6 eV for the Ce 3+ state. 7,28,33 The observed peaks for the U-CeO 2− x sample have the same peaks with a minor variation in their positions; nevertheless, a noteworthy change in the intensity of the peaks was observed.…”

“…The XPS spectrum of Ce 3d can be assigned to 3d5/2 and 3d3/2 spinorbit states denoted as U and V, respectively. The peaks U, U'', U''', V, V'' and V''' can be attributed to the chemical state of Ce 4+ , while U' and V' correspond to Ce 3+ state [55]. Thus, the cerium species present in both form of Ce 4+ and Ce 3+ on the surface of TiO2.…”

Co-doped titanium dioxide was synthesized by doping with manganese (Mn) and cerium (Ce) through a sol-gel method for the degradation of diclofenac (DCF). The synthesized products were successfully characterized by X-ray diffraction (XRD), Raman spectroscopy, Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), Nitrogen physisorption at 77 K, X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance (UV-DRS), photoluminescence spectroscopy (PL) and total organic carbon (TOC). It was shown that co-doping increased the specific surface area, improved the visible light absorption and extended the lifetime of photogenerated charge carriers. Furthermore, the results of the photocatalytic experiments show that the photodegradation rate of diclofenac can be approached by pseudo first-order kinetics and it followed the Langmuir-Hinshelwood model very well. The co-doped catalyst with 0.6 % Mn and 1 % Ce molar ratios appeared to be the most photoactive catalyst with 94 % of DCF removal and an apparent rate constant of 0.012 min -1 .
