Centimeter-long and large-scale micropatterns of reduced graphene oxide films : fabrication and sensing applications
Recently, the field-effect transistors (FETs) with graphene as the conducting channels have been used as a promising chemical and biological sensors. However, the lack of low cost and reliable and large-scale preparation ...
One-step growth of graphene–carbon nanotube hybrid materials by chemical vapor deposition
Graphene–carbon nanotube (CNT) hybrid materials were synthesized by simple one-step chemical vapor deposition (CVD) using ethanol as precursor. On a copper foil decorated with silicon nanparticles (Si NPs), a graphene film ...
3D grapheme-cobalt oxide electrode for high-performance supercapacitor and enzymeless glucose detection
Using a simple hydrothermal procedure, cobalt oxide (Co3O4) nanowires were in situ synthesized on three-dimensional (3D) graphene foam grown by chemical vapor deposition. The structure and morphology of the resulting 3D ...
3D graphene foam as a monolithic and macroporous carbon electrode for electrochemical sensing
Graphene, a single-atom-thick monolayer of sp2 carbon atoms perfectly arranged in a honeycomb lattice, is an emerging sensing material because of its extraordinary properties, such as exceptionally high specific surface ...
Fabrication of ultralong hybrid microfibers from nanosheets of reduced graphene oxide and transition-metal dichalcogenides and their application as supercapacitors
Two-dimensional materials have attracted increasing research interest owing to their unique electronic, physical, optical, and mechanical properties. We thus developed a general strategy for the fabrication of ultralong ...
