Synthesis of FeNi3 nanocrystals encapsulated in carbon nanospheres/reduced graphene oxide as a light weight electromagnetic wave absorbent

FeNi₃ nanocrystals encapsulated in carbon nanospheres/reduced graphene oxide (FeNi₃@C@rGO) composites have been synthesized through liquid-phase reduction reaction and then two-step hydrothermal processes followed by a pyrolysis process.
