摘要
We have successfully synthesized bulk samples of the infinite-layer compound LaNiO2 by reduction of the perovskite LaNiO3 using CaH2. First, LaNiO3 has been prepared using molten KOH at 450 degrees C. Next, the infinite-layer compound LaNiO2 has been synthesized by heating LaNiO3 mixed with a double stoichiometric excess of CaH2 in an evacuated Pyrex tube at 300 degrees C for 24 h.
