Morphology- and defect-coordinated prominent microwave absorption, thermal exhaustion, and electrical insulation in SnO2@SnP2O7@Sn2P2O7 hierarchical architectures

A series of SnO 2 @SnP 2 O 7 @Sn 2 P 2 O 7 hierarchical architectures synthesized via a facile hydrothermal–annealing route exhibit morphology- and defect-co-dominated microwave absorption, thermal exhaustion, and electrical insulation.
