“…The advent of graphene has provided a great impetus for the development of Ni-related carbon composites because its unique 2D laminated structure, excellent electrical conductivity, active surface functional groups, and native defects render it an attractive component for high-performance MAMs [169,170]. To date, many techniques, including hydrothermal reduction, chemical reduction, γ-ray irradiation, electroless plating, electroplating, and microwave-assisted heat reduction, have been utilized to anchor Ni and Ni-based alloy nanoparticles on the surface of rGO [35,145,[171][172][173][174][175][176][177][178][179][180][181][182]. In these cases, the loading content and the chemical composition of Ni and Ni-based alloy nanoparticles can easily be regulated, which creates a good opportunity to tailor their EM properties, and is thus favorable for the enhancement of microwave absorption performance.…”

Microwave absorption is emerging as a sustainable pathway through which to alleviate various problems induced by increasingly serious electromagnetic (EM) pollution and interference. As a platform for the conversion of EM energy, microwave-absorbing materials (MAMs) have received widespread attention and have been intensively studied in the past two decades. Among all kinds of materials with characteristic EM functions, the metal Ni has always been regarded as one of the most promising candidates, due to its good magnetic loss, compatible dielectric loss, and high Snoek's limit, as well as its easy production and abundant global reserves. However, it is still difficult for raw Ni particles to realize desirable absorption efficiency, and thus a lot of research has been carried out in the areas of microstructure optimization, alloying, and the composite design of Ni particles to significantly upgrade their microwave absorption performance. This review provides a comprehensive introduction to recent advancements in various high-performance Ni-related MAMs, including hierarchical Ni particles, Ni-based alloy particles, Ni-related composites with metal oxides/sulfides/conductive polymers/various carbon materials, and multicomponent Ni-related composites. Thanks to the synergistic effects between different components and elaborate microstructure designs, these Ni-related MAMs can produce a remarkable improvement in microwave absorption performance. Moreover, the challenges and prospects are also discussed in order to provide some new insights into further research in the field of Ni-related MAMs.
