Abstract

The polarizable organic/water interface is used to construct MoS₂ /graphene nanocomposites, and various asymmetrically dual-decorated graphene sandwiches are synthesized. High-resolution transmission electron microscopy and 3D electron tomography confirm their structure. These dual-decorated graphene-based hybrids show excellent hydrogen evolution activity and promising capacitance performance.

Keywords: 2D materials; asymmetric sandwiches; capacitance; electron tomography; hydrogen evolution.
