近期，我院研究生武亞可、朱艷龍（通訊）、張劉挺（通訊）等的研究成果“Constructing Ni-O-Zr interfaces to induce oxygen vacancies with enhanced metal-carrier interactions for robust hydrogen storage in magnesium hydride”在《Fuel》（IF=6.7）上發(fā)表。
論文簡(jiǎn)介如下：
By constructing Ni-O-Zr interfaces, oxygen vacancies were generated and the interaction between the metal and the support in the catalyst was significantly enhanced. This synergy between Ni0 and oxygen vacancies greatly boosted the catalytic activity of Ni50/ZrO2 in the hydrogen storage system. Experimental tests showed that the MgH2+10wt%Ni50/ZrO2 composite had a reduced initial hydrogen desorption temperature of 194.5 °C and released 6.30 wt%H2 within 10 minutes at 265 °C. Notably, this composite exhibited excellent low-temperature hydrogen absorption kinetics, initiating absorption at 29 °C and nearly completing it (6.67 wt%H2) at 134 °C. Furthermore, the activation energy for the modified MgH2 had been substantially decreased from 76.66 kJ/mol to 32.01 kJ/mol (absorption) and 155.84 kJ/mol to 83.93 kJ/mol (desorption), respectively. The presence of oxygen vacancies at the Ni-O-Zr interface significantly amplified the catalyst's charge conduction capabilities and provided a promising avenue for the development of effective catalysis for robust hydrogen storage.
