Ni Flower/MXene-Melamine Foam Derived 3D Magnetic/Conductive Networks for Ultra-Efficient Microwave Absorption and Infrared Stealth

open access: yesNano-Micro Letters, 2022
Ni-MXene/MF foam is synthesized via an electrostatic assembly and dip-coating process. The “micro-capacitor” structure of Ni/MXene and the 3D porous structure of MF endow the foam excellent impedance matching and wave absorption performance.

Renewable Hydrogen Production with Steam Reforming of Ethanol Using Siliceous Mesocellular Foam‐Supported Nickel Catalysts

open access: yesAdvanced Energy and Sustainability Research, Volume 4, Issue 11, November 2023., 2023
Herein, the use of nickel catalysts loaded on siliceous mesocellular foam to optimize the ethanol steam reforming reaction based on the aging of the support and the nickel loading is investigated. Fully aged catalyst and 10 wt% nickel loading reach optimal ethanol conversion and hydrogen selectivity from high material porosity, high dispersion of ...

Nickel‐Catalyzed Hydroborylative Polycyclization of Allenynes: an Atom‐Economical and Diastereoselective Synthesis of Bicyclic 5‐5 Fused Rings

open access: yesAdvanced Synthesis &Catalysis, Volume 364, Issue 10, Page 1716-1723, May 17, 2022., 2022
Abstract A diastereoselective synthesis of borylated bicyclic 5‐5 fused ring systems by a domino Ni‐catalyzed hydroborylative polycyclization of allenynes has been developed. The reaction provides two new C−C and one C−B bonds and constitutes an atom‐economical method.
