In this work, a modified separator coated with a functional layer of reduced graphene oxide (RGO) anchored by cerium oxide (CeO) nanoparticles was developed. The superior conductivity of RGO and chemical immobilization of high-ordered sulfur-related species (mainly LiS 4 ≤ n ≤ 8) of CeO yielded batteries with enhanced characteristics. A remarkable original capacity of 1136 mAh g was obtained at 0.1 C with capacity retention ratio of 75.7% after 100 charge/discharge cycles. Overall, these data indicate that the separator with CeO/RGO composite is promising to suppress the shuttling of polysulfides for better utilization of the active material.

A two-dimensional (2D) CeO-Pd-PDA/rGO heterojunction nanocomposite has been synthesised via an environmentally friendly, energy efficient, and facile wet chemical procedure and examined for hydrogen (H) gas sensing application for the first time. The H gas sensing performance of the developed conductometric sensor has been extensively investigated under different operational conditions, including working temperature up to 200 °C, UV illumination, H concentrations from 50-6000 ppm, and relative humidity up to 30% RH. The developed ceria-based nanocomposite sensor was functional at a relatively low working temperature (100 °C), and its sensing properties were improved under UV illumination (365 nm).

Here we presented a new facile strategy to fabricate ultrathin two-dimensional (2D) metal oxide nanosheets, by using polydopamine-coated graphene (rGO@PDA) as a template under simply wet-chemical conditions. Based on the strategy, graphene-like CeO-TiO mesoporous nanosheet (MNS-CeO-TiO) was prepared and was loaded with dispersive Ag nanoparticles (AgNPs) to obtain effective electrocatalysts (denoted as Ag/MNS-CeO-TiO) for electrochemical detection of superoxide anion (O). Characterizations demonstrated that MNS-CeO-TiO exhibited ultrathin thickness, larger specific surface area, and pore volume in comparison with its bulk counterpart.
