Rambutan-like Nb2O5@SHCs microspheres for improved microwave absorption performance

Abstract Rambutan-like Nb2O5 coated single-layer hollow carbon spheres (Nb2O5@SHCs) with unique morphology were synthesized by using SHCs as template via a simple hydrothermal method. The as-fabricated rambutan-like Nb2O5@SHCs presents improved electromagnetic wave (EMW) absorption performance, especially strong reflection loss (RL) and wide effective absorption bandwidth (EAB, RL
