composites for tunable low-frequency electromagnetic wave absorption

What is it about?

The rational design of electromagnetic wave (EMW) absorbing materials within the low-frequency range of 2-8 GHz has significant importance. However, achieving controlled low-frequency migration of electromagnetic materials absorption windows remains challenging. In this study, a MOF-on-MOF precursor (UiO-66@MIL-88B) is constructed via an in situ growth strategy and converted into CeO2/Fe@C (CFC) composites by temperature-programmed pyrolysis, enabling the shift of the absorption window toward lower frequencies.
