Nanosized Titanium Carbide MXene‐Supported Bimetallic Au@Ag Nanocubes as a Highly Efficient Catalyst for Nitroaromatics Reduction

Advanced Materials Interfaces, EarlyView.
Using NaBH4 as a reductant at room temperature, nanosized Ti3C2 MXene‐supported Au@Ag nanocubes (MX/Au@Ag NCs) function as an efficient catalyst for the reduction of nitroaromatics. The optimal 50%‐MX/Au@Ag NCs demonstrate excellent catalytic efficiency in the conversion of nitroaromatics to their respective amine derivatives, with reduction rates of ...

Morphology vs. Specific Surface Area: Which Plays the Leading Role in Microwave Absorption?

Advanced Materials Interfaces, EarlyView.
The role of morphology and specific surface area on microwave absorbing characteristics is systematically evaluated and compared. The matrix effect on microwave absorbing performance is studied using polyacetylurea. Implanted carbon nanotubes by red phosphorus and in situ polymerization of polyindole promoted microwave absorption.
