| Abstract Scope |
Graphene nanosheets, transition metal oxides, and metal–organic frameworks (MOFs) are attrative in considerations of specific surface area, active reaction sites, tunable pore structures etc and hence, have great potentials in environmental and energy applications. However, each individual has more or less drawbacks limiting their effective utilizations such as selective nitrogen oxide reduction or reversible energy storage.
We have developed a series of graphene supported hybrids, including graphene aerogel-oxide nanocomposites, graphene supported-MOF and derivatives, with various chemistries and morphologies. The surface areas, electrical properties, and the amount of active sites have been tuned through controllable processing conditions. The performances of these materials in selective NOx reduction, lithium-ion battery, and supercapacitors, have been assessed. Significant performance improvements have been achieved from these graphene-based hybrids compared to their individual counterparts. |
