近期，我院教师郑家广（通讯）、张刘挺（通讯），研究生张智、高东强等的研究成果“Heterostructured VF₄@Ti₃C₂ catalyst improving reversible hydrogen storage properties of Mg(BH₄)₂”在《Chemical Engineering Journal》（IF=16.744，中科院SCI一区）上发表。

论文简介如下：

For solid-state hydrogen storage, Mg(BH₄)₂ has long been recognized as a promising material. However, its higher thermal stability is distant from conditions for practical application. Herein, it is effectively established that VF₄ nanoparticles anchored on 2D Mxene Ti₃C₂ (VF₄@Ti₃C₂) have efficiently catalytic effects towards the hydrogen storage process of Mg(BH₄)₂. The MBH-VF₄@Ti₃C₂ sample started releasing hydrogen at 90 °C, which was 182 °C and 55 °C lower than those of additive-free Mg(BH₄)₂ and MBH-20Ti₃C₂ composites. Additionally, the MBH-20VF₄@Ti₃C₂ composite desorbed more than 8 wt% H₂ at 275 °C. The activation energies of dehydrogenation were reduced, and the improved reversibility of VF₄@Ti₃C₂-doped Mg(BH₄)₂ was also discussed. According to microstructural study, the heterostructural VF₄@Ti₃C₂ interacted with Mg(BH₄)₂ to produce VH_2.01 and metallic Ti during re/dehydrogenation, which worked as active species to improve hydrogen storage performance in Mg(BH₄)₂.
