offer the required chemical and thermal stability in oxi-dizing and reducing atmospheres and good oxygen ionic conductivity over a wide range of conditions 3 4 . The commonly used anode-supported SOFC design is based on porous cermets providing mechanical support and perme-ation path for the fuel and the reaction products. Ni–YSZ

Growth sintering and chemical states of Co supported on

Jan 28 2021 · In comparison with other transition metals including Ni Rh Pt and Au our studies demonstrate that Co on ceria exhibits a smaller particle size and higher thermal stability likely arising from strong metal–support interactions. The formed particles upon Co deposition at 300 K are present on the ceria surface after heating to 1000 K.

Enhancing Sintering Resistance of Atomically Dispersed

Installed on the zirconia nodes of a metal-organic framework (MOF) NU-1000 via targeted vapor-phase synthesis. The catalytic Pt clusters site-isolated by organic linkers are shown to exhibit high catalytic activity for ethylene hydrogenation while exhibiting resistance to sintering up to 200 degrees C.

The role of metal-support interactions in sintering and

tion of HDS catalyst by sintering of the support may also depend on other metal-support interac­ tions which simultaneously occur in given condi­ tions. Thus in the case of Co-Mo catalyst higher thermal stability of alumina support originates from formation of spinel-like regions with y­ Al20317. The study of model systems prepared on a
