Synthesis, structure and properties of bimetallic sodium rare-earth (RE) borohydrides, NaRE(BH4)4, RE = Ce, Pr, Er or Gd
Abstract
<p>Formation, stability and properties of new metal borohydrides within RE(BH<sub>4</sub>)<sub>3</sub>-NaBH<sub>4</sub>, RE = Ce, Pr, Er or Gd is investigated. Three new bimetallic sodium rare-earth borohydrides, NaCe(BH<sub>4</sub>)<sub>4</sub>, NaPr(BH<sub>4</sub>)<sub>4</sub> and NaEr(BH<sub>4</sub>)<sub>4</sub> are formed based on an addition reaction between NaBH<sub>4</sub> and halide free rare-earth metal borohydrides RE(BH<sub>4</sub>)<sub>3</sub>, RE = Ce, Pr, Er. All the new compounds crystallize in the orthorhombic crystal system. NaCe(BH<sub>4</sub>)<sub>4</sub> has unit cell parameters of a = 6.8028(5), b = 17.5181(13), c = 7.2841(5) Å and space group Pbcn. NaPr(BH<sub>4</sub>)<sub>4</sub> is isostructural to NaCe(BH<sub>4</sub>)<sub>4</sub> with unit cell parameters of a = 6.7617(2), b = 17.4678(7), c = 7.2522(3) Å. NaEr(BH<sub>4</sub>)<sub>4</sub> crystallizes in space group Cmcm with unit cell parameters of a = 8.5379(2), b = 12.1570(4), c = 9.1652(3) Å. The structural relationships, also to the known RE(BH<sub>4</sub>)<sub>3</sub>, are discussed in detail and related to the stability and synthesis conditions. Heat treatment of NaBH<sub>4</sub>-Gd(BH<sub>4</sub>)<sub>3</sub> mixture forms an unstable amorphous phase, which decomposes after one day at RT. NaCe(BH<sub>4</sub>)<sub>4</sub> and NaPr(BH<sub>4</sub>)<sub>4</sub> show reversible hydrogen storage capacity of 1.65 and 1.04 wt% in the fourth H<sub>2</sub> release, whereas that of NaEr(BH<sub>4</sub>)<sub>4</sub> continuously decreases. This is mainly assigned to formation of metal hydrides and possibly slower formation of sodium borohydride. The dehydrogenated state clearly contains rare-earth metal borides, which stabilize boron in the dehydrogenated state.</p>
