Low-temperature chemical synthesis of intermetallic TiFe nanoparticles for hydrogen absorption
نویسندگان
چکیده
Nanosizing of TiFe hydrogen storage alloy is conducted to facilitate its activation. Here, pure intermetallic nanoparticles (45 nm) were prepared using chemical reduction oxide precursors at 600 °C, which the lowest temperature ever used in synthesis. This was achieved a strong reducing agent (CaH2) molten LiCl. When for absorption, obtained surprisingly exhibited almost no absorption. The results demonstrated that are more difficult activate than bulk powder because oxidized surface layers become stabilized, prevents morphological change necessary their
