Study on catalytic mechanism of Yb2O3 on RE-Mg based hydrogen storage alloys
Source abstract
Abstract
Mg 90Ce 5Y 5 + x wt % Yb 2O 3 ( x = 2, 4, 6, 8, 10, 20) samples were prepared by high energy ball milling. The kinetic and thermodynamic properties of the composites were investigated by XRD, TEM, SEM, EDS and PCT. And all samples were tested for hydrogen absorption and desorption. The Mg 90Ce 5Y 5 + 10 wt % Yb 2O 3 sample displays the fastest hydrogen uptake rate, namely full hydrogenation takes only 125 min at 473 K. And it can fully dehydrogenate in just 75.6 min at 553 K. In addition, the value of E des is reduced to 95.5 kJ/mol. The improvement of dynamic performance is due to the change of microstructure: Yb 2O 3/YbH 2, YH 2 and CeO 2 provide plenty of active sites, and abundant defects and grain boundaries lead to the emergence of many high-energy regions and diffusion channels. The ∆ H value of Y10 (77.6 kJ/mol H 2) is not significantly lower than Mg 90Ce 5Y 5, indicating that the addition of Yb 2O 3 do not improve the thermodynamic properties.
