Abstract Cerium oxide (CeO 2), one of the most significant rare-earth oxides, has attracted
considerable interest over the past decades. This is primarily due to the ease in Ce 3+/Ce 4+ …

Developing robust nonprecious-metal electrocatalysts with high activity towards sluggish
oxygen-evolution reaction is paramount for large-scale hydrogen production via …

Herein, we have developed Ln 2 Ce 2 O 7 (Ln= Er, Ho) ceramic nanostructures through a
rapid and green sonochemical approach and scrutinized their photocatalytic efficiency …

The high-level contamination of pharmaceuticals in aquatic environment, and their toxicities
is a serious issue. This review highlights the use of ceria photocatalyst for treatment of …

Nitrogen doping sites greatly affected the electronic structure of catalysts. However,
identification of nitrogen doping sites in CeO 2 and their effects on catalytic ozonation have …

With the fast-growing populations and development, energy crisis have raised critical
requirements for utilization of clean solar energy. Some effective methods to capture and …

Oxynitrides of transition metals, alkaline earth metals and rare earth metals are intensively
investigated as a group of materials to expand and tune the properties of oxides. The …

In photocatalysis, surface engineered CeO 2 could be vital due to oxygen vacancies arise
from multiple valency, ie Ce 3+ and Ce 4+. This study reports photocatalytic properties of gC …

Noble-metal catalysts have been limited in removal of NO x in diesel vehicles due to the
poor NO x conversion in high air-fuel ratio, poor resistance to SO 2 and earth rarity. Thus …
