Synthesis and characterization of Co and Titania nanoparticle -intercalated rGO as a high capacitance electrode for CDI

Preparation of a Polypyrrole/Graphene Oxide Composite Electrode by Electrochemical Codeposition for Capacitor Deionization

“…Figure a shows the FTIR spectrum of the PPy/GO composite electrode. It can be seen from the FTIR spectrum that the peak values of PPy/GO at 1170, 1460, and 1538 cm –1 are related to the tensile vibration and aggregation of C–H, CC, and CN in PPy, respectively . The new peak of PPy/GO at 1040 cm –1 is caused by the C–O stretching vibration at 1058 cm –1 in GO.…”

Recent progress in renewable energy based-desalination in the Middle East and North Africa MENA region

“…However, during regeneration oppositely charged ions can be adsorbed to the switched polarity electrode; thus ion exchange membrane, like those used in ED/EDR, hence called membrane capacitive deionization MCDI, has been utilized to improve regeneration efficiency [57] , [116] . Most of the R&D efforts in CDI are geared to develop efficient electrodes with high electroadsorption capacity [91] , [119] .…”

Nano-manganese oxide and reduced graphene oxide-incorporated polyacrylonitrile fiber mats as an electrode material for capacitive deionization (CDI) technology

“… 37 ) and CoTiO 2 (ref. 38 ) are some materials used for this purpose. The common rationale of improving the CDI performance of rGO electrodes by MO includes the intercalation of rGO layers by the MO nanoparticles, 35,38 thereby increasing the surface area 34 and specific capacitance of the composite, 32,36 and improving the hydrophilicity, 32,34 whereas pseudocapacitance has also been identified as a possible cause.…”
