Hydrogen-induced structural transformation of AuCu nanoalloys probed by synchrotron X-ray diffraction techniques.
نویسندگان
چکیده
In situ X-ray diffraction measurements reveal that the transformation of a AuCu nanoalloy from a face-centered-cubic to an L10 structure is accelerated under a hydrogen atmosphere. The structural transformation rate for the AuCu nanoalloy under hydrogen above 433 K was found to be 100 times faster than that in a vacuum, which is the first quantitative observation of hydrogen-induced ordering of nanoalloys.

متن کاملTime-Resolved X-Ray Absorption Spectroscopy of Infrared-Laser Induced Temperature Jumps in Liquid Water
A time-resolved x-ray absorption study of the structural dynamics of liquid water on a picosecond time scale is presented. We apply femtosecond mid-infrared pulses to resonantly excite the intramolecular O-H stretching band of liquid water and monitor the transient response in the oxygen K-edge absorption spectrum with picosecond x-ray pulses. In this way, structural changes in the hydrogen bon...
متن کاملHydrogen Storage in light complex Hydrides – structural studies
The most important unsolved problem for the introduction of the Hydrogen Economy is efficient and safe storage of hydrogen. Alanates, compounds based on the AlH4 unit, are among the most promising metal hydrides for reversible hydrogen storage. The storage capacity is large, e.g. NaAlH4 can release 5.6 wt% hydrogen below 200 C. Work during the last years has revealed that Ti additives improve t...
