Oxygen‐free Layer‐by‐Layer Assembly of Lithiated Composites on Graphene for Advanced Hydrogen Storage
نویسندگان
چکیده
A facile hydrogenation-induced self-assembly strategy to synthesize lithium hydride (LiH) nanosheets with a thickness of 2 nm that are uniformly distributed on graphene is reported and designed. Taking advantage of LiH nanosheets with high reactivity and a homogeneous distribution on graphene support as a nanoreactor, the confined chemical synthesis of oxygen-free lithiated composites is effectively and efficiently realized.

Introduction A new class of materials called metal-organic frameworks (MOFs) introduced by Yaghi and coworkers has drawn the attention of many scientists [1] owing to their high porosity and their “cumulative” features originating from combining both inorganic and organic solids via assembly of metallic ions and organic ligands [1]. Their applications include gas separation/purification/storage...
