New Non-toxic And Low-cost Synthetic Crystals Can Convert Heat Into Electrical Energy
As shown in Eq.6, the Fe-Ni nanoparticle exsolution, together with the exhaustion of B-site cations and lattice oxygen, in a traditional way would trigger the stripping out of Sr cations to re-establish stoichiometry. In this study, the promising double perovskite Sr2Fe1.3Ni0.2Mo0.5O6-δ was selected as a prototype example to elaborate on the effects of the structure evolution of the perovskite scaffold on the stability of P-eNs15. Either controlling the A-site deficiency or implementing the topotactic ion exchange is anticipated to be…
