Synthesis, Activation, Characterization and Properties of Titanium Complexes/Graphene Ox ide Composite Materials

文章提出了一种"盆栽"型的钛配合物/氧化石墨烯复合储氢材料模型,以层状石墨为原料制备出高氧化程度的氧化石墨烯,探讨用氧化石墨烯来担载过氟钛酸铵进行储氢性能的可行性。氟钛酸铵/氧化石墨烯复合材料在333 K、453 K和573 K活化1 h后,在77 K,1.2 Mpa时储氢量分别为1.4 wt%、1.2 wt%和2.6 wt%。

The paper presents a way of a ＂pot＂ type titanium complexes/graphene oxide composite hydrogen storage material model. The layered graphite as material was prepared graphene oxide, the oxidation degree of the obtained high based on the structure of graphene oxide, the graphene oxide to explore the use of transition metal titanium for supporting the feasibility of hydrogen. Ammonium titanium composites, respectively 333 K, 453 K and 573 K activated 1 h, at 77 k, 1.2 Mpa, the hydrogen storage capacity was 1.4 wt%, 1.2 wt% and 2.6 wt%.
