A Facile Strategy for the Functionalization of Boron Nitride Nanotubes with Pd Nanoparticles

A facile in situ fabrication of palladium nanoparticles decorated boron nitride nanotubes (Pd-BNNTs) is described. The decoration of BNNTs was carried out by the self-regulated reduction of palladium chloride (PdCl₂) with the aid of sodium dodecyl sulfate (SDS). During the preparation process, the surfactant SDS plays a dual role: it aids the dispersibility of BNNTs and produces the reductant of CH₃(CH₂)₁₀CH₂OH. Then the CH₃(CH₂)₁₀CH₂OH can reduce Pd²⁺ to form Pd nanoparticles on the surface of BNNSs. The as-prepared Pd-BNNTs were characterized by field emission scanning electron microscopy, transmission electron microscopy, X-ray energy dispersive spectroscopy, and Fourier transform infrared spectroscopy. The results show that the Pd nanocrystalline particles can be deposited onto the BNNTs surface via this simple route. This approach constitutes a basis for the assembly and integration of nanoscale materials onto BNNTs and puts a light on the potential application of the BNNTs in electronic, catalysis, and hydrogen storage fields.
