Abstract
Core-shell Al@Ti nanoparticles are generated by ablation of a composite Ti-Al target in liquid isopropanol saturated with molecular hydrogen using a Nd:YAG laser with pulse duration of 10Â ps and repetition rate of 200Â kHz. The target is made of two plates of corresponding metals stacked together and placed into a flowing cell reactor. Transmission Electron Microscopy analysis of generated NPs reveals their core-shell structure with Ti core and Al shell. Average size of NPs determined by means of measuring disk centrifuge is around 40Â nm. Saturation of NPs by hydrogen is due to sharp dependence of its solubility in these metals on temperature. XRD studies of generated NPs show the peaks of both metallic Ti and Al with some amount of TiO2. No peaks of Ti-Al alloys are observed.
