文摘
- •
High-purity Co/C composites are prepared by optimizing pyrolysis of ZIF-67.
- •
The as-prepared Co/C composites show strong microwave absorption.
- •
Dual loss mechanism and matched impedance account for their microwave absorption.
- •
Ordered structure and pure Co phase contribute to upgrading their performances.
- •
The effective microwave absorption frequency can be tuned by the polyhedron size.
