RT Journal Article T1 Electro-spun graphene-enriched carbon fibres with high nitrogen-contents for electrochemical water desalination A1 Belaustegui, Yolanda A1 Zorita, Saioa A1 Fernández-Carretero, Francisco A1 García-Luis, Alberto A1 Pantò, Fabiola A1 Stelitano, Sara A1 Frontera, Patrizia A1 Antonucci, Pierluigi A1 Santangelo, Saveria AB Electro-spun carbon fibres doped with very high nitrogen concentrations (19–21 wt%) are obtained operating carbonisation at low temperature (500 °C). The as-synthesised fibres are evaluated as electrode materials for the electrochemical desalination of water. The effect of the enrichment of the nitrogen doped carbon fibres with thermally reduced graphene oxide is also investigated. The fibrous electrodes are able to remove amazing amounts of NaCl (17.0–27.6 mg/g) from a salty solution with an initial concentration of 585 mg/L. The nitrogen doping, which dramatically improves the wettability, plays a crucial role in determining the outstanding electro-sorption capacities of the fibres. It allows fully profiting of the more favourable pore size distribution in the graphene-enriched fibres, endowed with higher conductivity and capacitance, for the obtainment of unprecedented electro-sorption capacities via an extremely simple synthesis process, with no need of activation treatments.
