  Mixtures of 6LiBH4–RECl3–3LiH (RE = La, Er) have been produced by mechanochemical milling and their structure, thermal decomposition and reversibility have been studied. Hydrogen desorption starts around 300 °C in both composites. Heating to 400 °C yields LaB6, ErB4 and REH2+δ as major decomposition products. LiBH4 is destabilized by REH2+δ formed through decomposition of the parent borohydrides LiLa(BH4)3Cl and Er(BH4)3, respectively, and its hydrogen release temperature is reduced by 100 °C as compared to pure ball-milled LiBH4. The lanthanum-containing composite releases 4.2 wt.% H between 300 and 350 °C and shows a limited reversibility of ∼20% (340 °C, 10 MPa) probably due to hydrogen uptake by some amorphous boron-containing phases. For 6LiBH4–ErCl3–3LiH about 3 wt.% H is evolved up to 400 °C. Desorption against 0.5 MPa backpressure results in an increased reversibility (∼80%) as compared to vacuum (∼66%). Rehydrogenation (340 °C, 10 MPa) shows the formation of ErH3 and LiBH4 at drastically reduced conditions compared to pure LiBH4 (>400 °C, >10 MPa).

  The reversible hydrogen desorption–absorption of γ–Mg(BH4)2 ball milled with MoO3 and TiO2 has been investigated. No mechanochemical interaction between γ–Mg(BH4)2 and TiO2 was observed while for the 1:1 M ratio with MoO3, MoB2 was formed. There was little difference in the properties of γ–Mg(BH4)2 and γ–Mg(BH4)2 ball–milled with 0.02 mol percent TiO2 and MoO3. However, mixing in the same ratio γ–Mg(BH4)2 with TiO2 and MoO3 that had previously been subjected to high energy milling provided significant effects. For these materials, the DSC peaks appeared broader and were shifted to slightly lower temperatures, while the TPD peaks were decreased by ca. 20 °C, as compared to the pure γ–Mg(BH4)2. Faster hydrogen desorption kinetics was observed for the γ–Mg(BH4)2–MoO3 mixture. The reversible hydrogen storage capacity of γ–Mg(BH4)2–TiO2 at 271 °C was found to be 2.4 wt% H2 in the first cycle.

  Magnesium borohydride (Mg(BH4)2) is one of the most promising hydrogen storage materials. Its kinetics of hydrogen desorption, reversibility, and complex reaction pathways during decomposition and rehydrogenation, however, present a challenge, which has been often addressed by using transition metal compounds as additives. In this work the decomposition of Mg(BH4)2 ball-milled with CoCl2 and CoF2 additives, was studied by means of a combination of several in-situ techniques. Synchrotron X-ray diffraction and Raman spectroscopy were used to follow the phase transitions and decomposition of Mg(BH4)2. By comparison with pure milled Mg(BH4)2, the temperature for the γ → ε phase transition in the samples with CoF2 or CoCl2 additives was reduced by 10–45 °C. In-situ Raman measurements showed the formation of a decomposition phase with vibrations at 2513, 2411 and 766 cm−1 in the sample with CoF2. Simultaneous X-ray absorption measurements at the Co K-edge revealed that the additives chemically transformed to other species. CoF2 slowly reacted upon heating till ~290 °C, whereas CoCl2 transformed drastically at ~180 °C.

  The effect of transition metal fluorides on the decomposition of NaBH4 has been investigated for NaBH4 ball milled with TiF3, MnF3 or FeF3. The compounds were examined by thermal programmed desorption with residual gas analysis, thermo gravimetric analysis and volumetric measurements using a Sieverts-type apparatus. The phase formation process during thermal decomposition was studied by in situ synchrotron radiation powder X-ray diffraction on the as-milled powders. NaBF4 was among the products in all mechano-chemical reactions. 11B-NMR spectra analysis gave NaBF4:NaBH4 ratios of 1:150 for Na–Ti, 1:40 for Na–Mn, and 1:10 for Na–Fe. Pure NaBH4 possessed a hydrogen release onset temperature of 430 °C. The hydrogen release in the NaBH4–MnF3 system began as low as 130 °C. FeF3 decreased the onset temperature to 161 °C and TiF3 to 200 °C. TiF3 reacted completely with NaBH4 below 320 °C. All the examined systems have negligible emissions of diborane species. H-sorption studies performed at selected temperatures above 300 °C exhibited relatively fast desorption kinetics. Partial hydrogen re-absorption was observed for the Na–Mn and Na–Fe samples.

  Mechanochemical reactions between KBH4 and KBF4 result in the formation of potassium fluoroborohydrides K(BHxF4−x) (x = 0–4), as determined by 11B and 19F solid state NMR. The materials maintain the cubic KBH4 structure. Thermogravimetric (TG) data for a ball-milled sample with KBH4:KBF4 = 3:1 are consistent with only desorption of hydrogen.

  Oxygen-containing yttrium hydride thin films exhibit photochromic behavior: Transparent thin films reversibly switch from a transparent state to a photodarkened state after being illuminated with UV or blue light. From optical spectrophotometry and ellipsometry measurements of the transparent state and photodarkened state, it is concluded that the photochromic effect can be explained by the gradual growth, under illumination, of metallic domains within the initial wide-band-gap semiconducting lattice. This conclusion is supported by Raman measurements.
