Facile synthesis of Ni/ZnO composite: Morphology control and microwave absorption properties

Facile design of a ZnO nanorod–Ni core–shell composite with dual peaks to tune its microwave absorption properties

“…29,30 Liu 31 prepared Ni/ZnO nanocapsules by a modied arc-discharge technique, and these Ni/ZnO nanocapsules show excellent microwave absorption properties. In our previous study, 32 coreshell structured Ni/ZnO (ZnO polyhedron coating) composites with superior absorption were fabricated by a two-step method. The microwave absorption mainly originated from the coreshell structure and ZnO polyhedrons.…”

Electromagnetic Wave Absorption Properties of Core-Shell Ni-Based Composites

“…Ni microspheres were prepared based on our previous publication [15]. Ni/ZnO composites were synthesized through a facile hydrothermal method [23]. Typically, 0.05 g of the as-obtained Ni microspheres was distributed in 60 mL distilled water.…”

“…At the high content of NH 3 •H 2 O, long ZnO nanorods could be produced because of the fast growth rate along the [0001] direction [27]. [23]…”

Controlling the electric permittivity of honeycomb-like core–shell Ni/CuSiO3 composite nanospheres to enhance microwave absorption properties

“…4,11,12 Various types of core-shell composite microstructures have been reported based on Ni as the core material and different shell materials including polymers, C, SnO 2 , TiO 2 , SiO 2 , ZnO, ZnS, CuO, and graphene composites. 9,[13][14][15][16][17][18][19][20] Zhao et al reported ZnS-wrapped Ni spheres that exhibited a reection loss (RL) of À42.4 dB with high effective bandwidth. 17 Deng et al prepared ZnO nanorod-coated Ni spheres and reported an RL of À30.2 dB.…”
