不斷擴大的全球能源危機除了氫之外基本上沒有有效的治療方法。 對於改變依賴化石燃料的經濟來說，一種特別有吸引力的替代能源是氫。
在這項研究工作中，研究了具有精細調整微觀結構的商用鎂合金AZ31-Mg合金和AZ91-Mg合金的儲氫性能。 使用不同的加工方法，包括等通道角擠壓 (ECAP) 和高能球磨 (HEBM)，對合金的微觀結構和相組成進行細化。 使用 X 射線衍射 (XRD)、掃描電子顯微鏡 (SEM) 和光學數字顯微鏡 (ODM) 對氫吸收和解吸過程中發生的微觀結構和相變進行了表徵。 在300°C和375°C的溫度下，使用Sieverts型裝置測量所製備的合金的氫化計算。 ECAP 和 HEBM 工藝均顯著改善了加工合金的氫化性能。 經處理的合金中不存在壓力滯後。 結果表明，粉末形貌和塊體樣品的微觀結構均顯著影響AZ鎂合金的吸放氫性能。
在接下來的步驟中，我們採用化學氣相沉積（CVD）技術合成了WS2無機納米管，並通過實驗研究了AZ31-WS2納米管和Pd（AZ31-WS2 NTs/Pd）複合材料的活化和儲氫動力學。 。 採用機械球磨製備了三種不同類型的AZ31-WS2 NTs/Pd複合材料，並使用透射電子顯微鏡（TEM）表徵了形貌和納米管結構。 採用差示掃描量熱法（DSC）分析熱分解性能。 WS2NTs/Pd催化劑的加入大大增強了脫氫特性，催化機理分析將為無機納米管和過渡金屬在儲氫材料開發中的應用提供指導

The expanding global energy crisis essentially has no effective treatment other than hydrogen. A particularly attractive alternative energy source for shifting an economy dependent on fossil fuels is hydrogen.
In this research work, the hydrogen storage properties of commercial magnesium alloys with a finely tuned microstructure, AZ31-Mg alloy, and AZ91-Mg alloy, are investigated. The microstructure and phase composition of the alloys were refined using varying processing methods, including equal channel angular pressing (ECAP) and high energy ball milling (HEBM). The microstructure and phase changes that occurred throughout the hydrogen absorption and desorption processes were characterised using X-ray diffraction (XRD), scanning electron microscopy (SEM), and optical digital microscopy (ODM). At a temperature of 300°C and 375°C, the Sieverts' type apparatus is used to measure the hydrogenation calculations of prepared alloys. Both the ECAP and HEBM processes significantly improved the hydrogenation properties of processed alloys. No pressure hysteresis was present in the treated alloys. It was demonstrated that the morphologies of powders and the microstructure of bulk samples both significantly influence the hydrogen absorption and desorption properties of AZ magnesium alloys.
In the steps that followed, we synthesised WS2 inorganic nanotubes using the chemical vapour deposition (CVD) technique, and we experimentally investigated the activation and hydrogen storage kinetics of the composite made of AZ31-WS2 nanotubes and Pd (AZ31-WS2 NTs/Pd). Mechanical ball milling was used to prepare three different types of AZ31-WS2 NTs/Pd composites, and transmission electron microscopy (TEM) was used to characterise the morphologies and nanotube structures. Differential scanning calorimetry (DSC) was used to analyse the thermal decomposing properties. The dehydrogenation characteristics were greatly enhanced by the inclusion of WS2NTs/Pd catalysts, and the catalytic mechanism analysis would provide guidance for the use of inorganic nanotubes and transition metals in the development of hydrogen storage materials
