Two‐Dimensional MXene‐Polymer Heterostructure with Ordered In‐Plane Mesochannels for High‐Performance Capacitive Deionization

Angewandte Chemie International Edition, Год журнала: 2021, Номер 60(51), С. 26528 - 26534

Опубликована: Ноя. 8, 2021

The application of traditional electrode materials for high-performance capacitive deionization (CDI) has been persistently limited by their low charge-storage capacities, excessive co-ion expulsion and slow salt removal rates. Here we report a bottom-up approach to the preparation two-dimensional (2D) Ti3 C2 Tx MXene-polydopamine heterostructure having ordered in-plane mesochannels (denoted as mPDA/MXene). Interfacial self-assembly mesoporous polydopamine (mPDA) monolayers on MXene nanosheets leads mPDA/MXene heterostructure, which exhibits several unique features: (1) undergoes reversible ion intercalation/deintercalation possesses high conductivity; (2) mPDA layers establish redox characteristics Na+ selectivity, also help prevent self-stacking oxidation MXene; (3) enable smooth transport ions at internal spaces this stacked 2D material. When applied an material CDI, exhibit top-level CDI performance cycling stability compared those so far reported materials. Our study opens avenue rational construction MXene-organic hybrid heterostructures, further motivates development

Abstract The highly efficient energy conversion of the polymer‐electrolyte‐membrane fuel cell (PEMFC) is extremely limited by sluggish oxygen reduction reaction (ORR) kinetics and poor electrochemical stability catalysts. Hitherto, to replace costly Pt‐based catalysts, non‐noble‐metal ORR catalysts are developed, among which transition metal–heteroatoms–carbon (TM–H–C) materials present great potential for industrial applications due their outstanding catalytic activity low expense. However, during testing in a two‐electrode system high complexity have become big barrier commercial applications. Thus, herein, simplify research, typical Fe–N–C material with relatively simple constitution structure, selected as model catalyst TM–H–C explore improve such kind Then, different types active sites (centers) coordination systematically summarized discussed, possible attenuation mechanism strategies analyzed. Finally, some challenges faced prospects proposed shed light on future development trend advanced catalysis.
