Application

  • Composites.
  • Conductive inks.
  • Electrodes for LiB.
  • Energy storage & harvesting applications.
  • Bio-medical applications.

Preparation Note

Preferred dispersing organic solvents: pyrrolidones and chlorinated solvents, also dispersible in acetone, ethyl acetate, dimethyl formamide, ethylene glycol, or 1,2-dimethoxyethane at concentration ≤0.1 mg/mL after bath sonication for 15 min with stability for a few hours.
  • Less preferred dispersing organic solvents: cyclohexanone and γ-butyrolactone.
  • Aqueous dispersions are possible at 0.1 mg/mL with triton-X-100, sodium cholate and deoxycholate and cellulose-based surfactants.

Analysis Note

Raman Spectroscopic Data:
ID/IG = 1.84±0.25
I2D/IG = 2.12±0.32
2D FWHM = 41 cm-1

Since its discovery little more than a decade ago,1 the two-dimensional (2D) allotrope of carbon—graphene—has been the subject of intense multidisciplinary research efforts.

Catalytic water splitting produces hydrogen crucial for renewable energy, petroleum refining, and chemical industry applications like methanol production.

Advances in scalable synthesis and processing of two-dimensional materials
