Poster: Synthesis and characterization of Ce-Mg based hydrogen storage alloys

Rare earth-Mg based alloys are interesting candidates for efficient and sustainable hydrogen storage. Some recently studied compounds include Ce3-xMgxCo9, Nd3-xMgxCo9 and La2Mg17 phase and its transition metal doped variants are already being studied for their hydrogen absorption and desorption properties. In this study, we will explore the synthesis and characterization of Ce-Mg alloys with varying compositions to optimize their hydrogen storage performance. The alloys will be synthesized using high-temperature solid-state reactions and characterized by X-ray diffraction (XRD) to assess crystal structure, scanning electron microscopy (SEM) for phase purity and microstructural analysis. Characterization techniques such as thermogravimetric analysis (TGA) will be conducted to evaluate hydrogen storage capacity and cycling stability. Doping will be one of our key strategies for tuning the alloy properties to enhance hydrogen storage efficiency. We expect to identify chemically tuned Ce-Mg alloys that will demonstrate favorable hydrogen uptake characteristics at ambient pressures and relatively low temperatures, positioning them as strong candidates for next-generation hydrogen storage materials.
