“…published a review on CDI electrode materials, which highlighted the differences between non‐faradaic and faradaic electrodes. The group has pointed out that faradaic CDI electrodes reach higher salt adsorption capacities (greater than 55 mg g −1 ) than non‐faradaic electrodes [49] . The difference in performance can be attributed to their adsorption mechanisms.…”

Capacitive deionization (CDI) is a potential technology to provide cost efficient desalinated and/or softened water. Several efforts have been invested in the fabrication of CDI electrodes that not only has outstanding performance but also high chance of large scalability. In this personal account, the different techniques in developing carbon‐based materials are presented together with its actual effect on the surface and electrochemical properties of carbon. The categories presented are based on the studies done by the Electrochemical Reaction and Technology Laboratory, the Ertl Center, different research groups in South Korea, and selected papers from the past three years. Our perspective about research gaps and prospects are also included with the aim to increase interest for CDI research.

“…Traditional CDI electrodes are carbon-based, such as active carbon (AC), hierarchically porous carbon (HPC), carbon nanotubes (CNT), and graphene (GE). A summary of the properties of this different class of materials can be found in Table 2 , adapted from Zhao et al [ 112 ]. Carbon-based materials tend to be favored for CDI applications, as they are low cost and have desirable SC and ESC properties, which are correlated with the SA .…”

“…Both electrodes are charged with an applied voltage, causing salt ions to migrate from the solution into the electrical double layers (EDLs) along the pore surfaces at the electrode/solution interphase, generating clean fresh water. Once the surface of the electrodes is saturated with the salt ions, a discharge step is used by stopping or reversing the applied potential to release the salt ions into a brine stream and regenerate the sorbent (Figure 13) [112][113][114][115]. The CDI electrodes can be categorized into non-faradaic electrodes and faradaic electrodes according to the ion adsorption mechanism [37,113,114,116].…”

Metal–organic-frameworks (MOFs) are emerging materials used in the environmental electrochemistry community for Faradaic and non-Faradaic water remediation technologies. It has been concluded that MOF-based materials show improvement in performance compared to traditional (non-)faradaic materials. In particular, this review outlines MOF synthesis and their application in the fields of electron- and photoelectron-Fenton degradation reactions, photoelectrocatalytic degradations, and capacitive deionization physical separations. This work overviews the main electrode materials used for the different environmental remediation processes, discusses the main performance enhancements achieved via the utilization of MOFs compared to traditional materials, and provides perspective and insights for the further development of the utilization of MOF-derived materials in electrified water treatment.

Graphene, an SP2 hybridized 2‐D atomic crystal, has been one of the most significant materials of the current century. Researchers in the recent years find graphene to be highly appealing for its superlative electrochemical energy storage applications and some of its unique features such as fractional quantum hall effect which is even exhibited in normal temperatures such as room temperature, ballistic conduction of charge carriers along with the exhibition of ambipolar electric field effect and modifiable bandgap. Enhanced electrochemical performances have been achieved by coalescing graphene with other electrochemical materials. This review focuses on various bio‐precursors involved in the synthesis of graphene and its diverse production methods along with their merits and demerits. It also summarizes the ensuing features and macro‐structural complexity of the graphene‐derived structural composites as well as its applications as competent electrode material in energy storage devices. It specifically endeavors in providing a comprehensible idea on the availability of a variety of biomass sources and its synthesis techniques for a better and optimized mass production of graphene with uncompromising purity as well as the perspectives of the graphene‐based composites that pave path for its improved application in advanced storage devices. This review article casts light upon the enormous opportunities of graphene production with easy synthesizing techniques that could aid in the fabrication of high performance of supercapacitors.
