Insight into MgO-supported NiO reactivity from atomic-scale electronegativity for oxygen carrier design and catalyst production applications

Lattice variation as a function of concentration and grain size in MgO–NiO solid solution system

“…NiO exhibits catalytic activity for various reactions, such as CO oxidation and hydrocarbon reforming, while MgO is known for its basicity and ability to promote reactions involving acid-base interactions. Combining these materials can create synergistic effects, leading to enhanced catalytic performance and selectivity [ 31 , 32 ]. Furthermore, NiO is an antiferromagnetic material with a Néel temperature above room temperature.…”
