General description

N-doped graphene may be prepared by chemical vapor deposition (CVD), direct synthesis of N-graphene and also by electrical annealing of graphene nanoribbons in NH3 in the presence of NH3.Another technique of preparing N-doped graphene by microbial reduction of graphene oxide was reported. N doping alters the electrical properties of graphene effectively by modifying its band structure. A report also shows that doped graphene can act as excellent support for Pt catalysts and show better performance in Li ion batteries.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". High concentrated graphene oxide sheets provide the prerequisite viscosity to bind the electrode materials together and enable 3D printing. Using water as a green solvent makes this aqueous ink system feasible for processing and drying safety and low cost. Click here for more information.
