Embodiment 1

[0020] 1. In an argon atmosphere glove box, weigh about 1g of LaNi through an electronic balance 5 Pour the sample into an agate mortar and grind it thoroughly until the particle size of the sample powder is between 10 μm and 20 μm. The particle size of the powder is confirmed by SEM, and then 0.04g LaNi is weighed by an electronic balance in an argon atmosphere glove box. 5 Powder samples are loaded into small glass weighing boats for later use.

[0021] 2. Move the capillary holder into the argon atmosphere glove box, and insert a paper funnel into the funnel at the upper end of the capillary, then pour all the powder samples in the glass weighing boat into the weighing paper funnel, and use a wire of about 1mm Push the powder sample into the funnel of the capillary.

[0022] After there is no powder sample in the weighing paper funnel, remove the weighing paper funnel, take out the transparent plexiglass tube together with the sponge and the capillary with the funnel at th...

Abstract

The invention relates to a quick preparation method for a synchrotron radiation X-ray diffraction test sample of a hydrogen storage material and relates to the technical field of synchrotron radiation X-ray diffraction test. The quick preparation method comprises the following steps: inserting a capillary tube into a sponge; hermetically covering the sponge in a transparent organic glass fixing bracket; supporting a piece of transparent organic glass on a metal fixing bracket; filling the ground sample powder into the capillary tube through a weighing paper funnel; packaging an opening end of the capillary tube with vacuum grease, wherein the grinding, filling and packaging processes of the sample powder are all performed in an argon glove box. According to the quick preparation method, the dosage of the sample is reduced, the quick efficient preparation for the test sample is realized and the hydrogen storage material is prevented from being oxidized, so as to acquire the high-accuracy synchrotron radiation X-ray spectrums of the material and know the microstructure of the material according to the X-ray spectrums.

Description

technical field [0001] The invention relates to the technical field of synchrotron radiation X-ray diffraction testing, in particular to a rapid preparation method for a hydrogen storage material synchrotron radiation X-ray diffraction test sample. Background technique [0002] The energy crisis and environmental pollution have prompted many countries to develop various new energy technologies. Hydrogen energy is recognized as one of the most effective solutions to replace fossil energy, because it has the advantages of abundant sources, convenient use, and no pollution. However, for large-scale applications, hydrogen must be stored safely and efficiently. Hydrogen storage materials can safely store hydrogen, but the disadvantage is that the reversible hydrogen storage capacity is not high, and further development is needed. In addition, different engineering applications have different requirements on the performance of hydrogen storage materials, which involves material ...
