The atomic‐local environment of catalytically active sites plays an important role in tuning the activity of carbon‐based metal‐free electrocatalysts (C‐MFECs). However, the rational regulation of the environment is always impeded by synthetic limitations and insufficient understanding of the formation mechanism of the catalytic sites. Herein, the possible cleavage mechanism of carbon nanotubes (CNTs)...

In article number 2302686, Jiurong Liu, Zhihui Zeng, and co‐workers report a type of N‐doped carbon nanotube encapsulated CoNi alloy nanocomposites with diverse heterostructures, which deliver excellent electromagnetic wave absorption performance involving a minimum reflection loss of −84.0 dB at the thickness of 3.2 mm and a maximum effective bandwidth of 4.3 GHz.
Developing carbon encapsulated magnetic composites with rational design of microstructure for achieving high‐performance electromagnetic wave (EMW) absorption in a facile, sustainable, and energy‐efficiency approach is highly demanded yet remains challenging. Here, a type of N‐doped carbon nanotube (CNT) encapsulated CoNi alloy nanocomposites with diverse heterostructures are synthesized via the facile,...
