Recently, the influence of polar facets on the gas sensing performance of metal oxides has
drawn much attention, yet the facet-dependent gas sensing properties of rare earth oxides …

CO2 hydrogenation to methane is gaining increasing interest as one of the most promising
ways to store intermittent renewable energy in the form of chemical fuels. Ni particles …

In the present study, we perform systematic density functional investigations on the single-
atom Pt catalysts dispersed on CeO2 (111),(110), and (100) surfaces. The structural and …

Ni-based catalysts have garnered significant attention as alternative materials for the
methanol oxidation reaction with its interesting Ni2+/Ni3+ redox couple. Enhancing the …

Fundamental understanding of support effects and metal–support interaction is critical in
heterogeneous catalysis. In this work, theoretical investigations are carried out to study the …

CeO2 nanocubes (c-CeO2), nanoparticles (p-CeO2), and nanorods calcined at 500° C (r-
CeO2-500) and 700° C (r-CeO2-700) were used as supports to synthesize a series of …

The asymmetric oxygen vacancies on the surface of doped oxides and at the interface
between the metal and oxide are commonly regarded as the real active sites for the …

Anion exchange membrane fuel cells (AEMFCs) offer several important advantages with
respect to proton exchange membrane fuel cells, including the possibility of avoiding the use …

The effects of transition metal (Fe, Co and Ni) modification (adsorption, insertion and
substitution) of CeO2 surfaces on oxygen vacancy formation and CH4 activation are studied …

Ceria (CeO 2) based catalysts have been widely reported as potential materials for
elemental mercury (Hg 0) oxidation in flue gas. However, the effect of sulfur dioxide (SO 2) …
