The obtained results indicate the presence of well-crystalized Co\(_3\)O\(_4\) nanoparticles onto the rGO nanosheets in the lamellar structure of rGO/Co\(_3\)O\(_4\). Despite slight decrease in BET specific surface area (from 389.9 m\(^2\)/g of rGO to 218.7 m\(^2\)/g of rGO/Co\(_3\)O\(_4\)), cyclic voltammetry studies show that the rGO/Co3O4 electrode exhibited high specific capacitance (95.8 F/ g at 50 mV/ s) with redox properties. The synthesized composites are expected to be a potential electrode candidate in supercapacitor as well as in hybrid capacitive deionization (HCDI) system for the desalination purpose.}, number={4}, journal={Communications in Physics}, author={Pham, Thi Nam and Nguyen, Thi Thom and Nguyen, Thi Thu Trang and Dinh, Thi Mai Thanh and Vo, Thi Kieu Anh and Nguyen, Anh Son and Tran, Dai Lam}, year={2020}, month={Dec.}, pages={409} }
