Cyclic oxygen exchange capacity of Ce-doped V2O5 materials for syngas production via high-temperature thermochemical-looping reforming of methane

Cerium doping into the V2O5 lattice forms a reversible V2O3/VO redox pair after sequential methane partial oxidation and CO2/H2O splitting reactions and produces syngas (H2, CO) with fast rates and high oxygen exchange capacity.

Influence of cerium doping on Cu–Ni/activated carbon low-temperature CO-SCR denitration catalysts

In the process of denitrification, the reaction between NO and CO (NO + CO → N2 + CO2) occurs. There will be a redox reaction between copper, nickel and cerium (Cu2+ + Ce3+ → Cu+ + Ce4+, Ni3+ + Ce3+ → Ni2+ + Ce4+).

Synthesis of Ce-doped SnO2@Ti3C2 nanocomposites for enhanced lithium-ion storage

It is accepted that cerium doping is a great way to stabilize the structure of metallic oxides and improve the electrochemical performance of lithium (Li)-ion batteries (LIBs). Using a simple hydrothermal method, we doped Ce into tin-based oxides and synthesized Ce-doped SnO2@Ti3C2 nanocomposites with Ti3C2-MXene as a framework. The as-prepared Ce-doped SnO2@Ti3C2 nanocomposites show higher surface area and lower Li+ diffusion barrier, and the galvanostatic charge/discharge cycle stability is better than that of SnO2@Ti3C2. Additionally, the nanocomposites exhibit excellent initial discharge capacity (1482.6 mAh g[Formula: see text] at 100 mA g[Formula: see text] and a remarkable cycle rate performance. After 150 cycles, the achieved discharge capacity remained at 310.8 mAh g[Formula: see text]. This study provides a new method of using two-dimensional (2D) layered materials and rare earth elements as lithium-ion storage materials.
