Electrocapacitive Deionization: Mechanisms, Electrodes, and Cell Designs

Advanced Functional Materials, Год журнала: 2023, Номер 33(18)

Опубликована: Фев. 26, 2023

Abstract Capacitive deionization (CDI) is an emerging water desalination technology for removing different ionic species from water, which based on electric charge compensation by these charged species. CDI becoming popular because it more energy‐efficient and cost‐effective than other technologies, such as reverse osmosis distillation, specifically in dealing with brackish having low or moderate salt concentrations. Over the past decade, research field has witnessed significant advances used electrode materials, cell architectures, associated mechanisms applications. This review article first discusses ion storage/removal carbon Faradaic materials aided advanced situ analysis techniques computations. It then summarizes progress toward terms of structure, surface chemistry, composition. More still, architectures highlighting their design concepts. Finally, current challenges future directions are summarized to provide guidelines research.

Inspired by Wood: Thick Electrodes for Supercapacitors

ACS Nano, Год журнала: 2023, Номер 17(10), С. 8866 - 8898

Опубликована: Май 1, 2023

The emergence and development of thick electrodes provide an efficient way for the high-energy-density supercapacitor design. Wood is a kind biomass material with porous hierarchical structure, which has characteristics straight channel, uniform pore good mechanical strength, easy processing. wood-inspired low-tortuosity vertically aligned channel architecture are highly suitable construction electrochemical supcapacitor high energy densities. This review summarizes design concepts processing parameters electrode supercapacitors inspired by natural woods, including wood-based structural regulation, electric double layer capacitances (EDLCs)/pseudocapacitance construction, electrical conductivity optimization. In addition, optimization strategies preparing wood-like structures (e.g., 3D printing, freeze-drying, aligned-low tortuosity channels) also discussed in detail. Further, this presents current challenges future trends structures. As guideline, brilliant blueprint will promote sustainable structure broaden application scopes.

Oxygen‐Rich Cobalt–Nitrogen–Carbon Porous Nanosheets for Bifunctional Oxygen Electrocatalysis

Advanced Functional Materials, Год журнала: 2022, Номер 32(23)

Опубликована: Март 4, 2022

Abstract Metal–nitrogen–carbon (M–N–C) materials have attracted much interest in bifunctional oxygen‐involving electrocatalysis for rechargeable Zn–air batteries. Such M–N–C electrocatalysts with M–N x sites show good activity the oxygen reduction reaction (ORR) but moderate evolution (OER). Herein, an oxygen‐rich material (O–Co–N/C) a highly porous nanosheet structure is reported as electrocatalyst, which prepared by direct pyrolysis of ultrathin CoO nanosheets decorated zeolitic imidazolate framework‐8 nanoparticles under inert atmosphere. Particularly, Co O–Co–N/C electrocatalyst contain both Co–N and Co–O coordination environments to provide intrinsic active ORR OER, respectively. Furthermore, electrochemical studies that catalyst retains comparable common half‐wave potential 0.85 V vs reversible hydrogen electrode better OER overpotential 0.29 at current density 10 mA cm −2 . This study provides insights into development effective metal centers coordinated nitrogen atoms.
