Key Points

CVD growth of boron nitride nanotubes was selectively enhanced using a specific oxidation-controlled catalyst.
The oxidation-controlled catalyst combined Ni and Pd, resulting in improved interactions that favored the growth of core/shell nanowires.
Using advanced techniques like TEM and DFT provided insights into the catalyst behavior during the growth process.
These findings indicate potential advancements in the fabrication of nanostructures for various applications.

Implication

An oxidation-controlled Ni–Pd catalyst promotes selective CVD growth of BNNTs at 1100 °C, suggesting effective catalyst interactions.

Abstract

An oxidation-controlled supported Ni–Pd catalyst enables selective CVD growth of BNNTs and MgO–BN core/shell nanowires at 1100 °C; TEM/DFT show quasi-liquid catalyst and strong h-BN interaction governing tip growth.
