Microwave absorption has been very critical for many civil and military applications. In this study, we report for the first time the porous plasmonic Cu9S5 nanonets possessing an excellent microwave absorption performance with a large reflection loss (RL) of −55.03 dB (over 99.999% absorption efficiency) and a maximal effective bandwidth of 4.15 GHz (RL ≤ −10 dB). The impressive microwave absorption performance is attributed to the large pore volume, multireflection of electromagnetic waves, and increased microwave absorption sites on the unique porous structure and the impressive plasmonic properties of Cu9S5 nanonets. The results have demonstrated potentially promising prospects of plasmonic Cu9S5 nanonets as a new material candidate for microwave absorption.
