Abstract Capacitive deionization (CDI) desalination has attracted much attention due to innovations in electrode manufacturing. In this study, a combination of reduced graphene oxide (rGO) doped with different ratios of titanium, nickel and cobalt oxides. The rGO-15TiO2 electrode achieved the highest specific capacitance of 635.1 F/g. The rGO-15TiO2 electrode reaching 24.578 mg/g salt removal at 1.2 V with initial conductivity 150µs/cm. Furthermore, The electrochemical measurements demonstrated that rGO-15(50Ni-50Co) electrode revealed the best capacitive performance. That samples achieved specific capacitance 461.5 F/g. Also Co, and titanium oxide nanoparticles (10 rGO-1Co-xTiO2, x= 1~9) was used. The cyclic voltammetry results showed that Co/rGO-Ti7 had the best performance in terms of capacitance (720 F/g) and salt removal, reaching 26.1 mg/g. Reactor design for continuous reactor for rGO-15TiO2 was given and shows that volume of reaction is about 433 ml for flow rate of 15ml/min. While for Co/rGO-Ti7 about 381.2ml for flow rate of 20ml/min. |
