NiFe 2 O 4 as an active component of a platinum group metal-free automotive three-way catalyst
To develop a platinum group metal (PGM)-free automotive three-way catalyst (TWC), we investigated the structure–activity relationship for Fe–Ni oxide catalysts and found NiFe 2 O 4 with a spinel structure is an active component of the three-way catalytic reaction (NO–C 3 H 6 –CO–O 2 ). The NiFe 2 O...
