Mixed matrix membranes (MMMs), conjugating the advantages of flexible processing‐ability of polymers and high‐speed mass transfer of porous fillers, are recognized as the next‐generation high‐performance CO2 capture membranes for solving the current global climate challenge. However, controlling the crystallization of porous metal‐organic frameworks (MOFs) and thus the close stacking of MOF nanocrystals...
Gas Separation Membranes
In article number 2208177, Ming‐Jie Yin, Quan‐Fu An, and co‐workers propose a “confined swelling coupled solvent controlled crystallization” strategy to rapid preparation of mixed matrix membrane for CO2 capture. The fabricated membrane exhibits 4‐fold enhancement in CO2 permeability, benefiting from the high ZIF‐8 loading creating additional speedy mass transfer channel for...
Effective utilization of solar energy in battery systems is a promising solution to achieve sustainable and green development. In this work, a photoassisted Fe–air battery (PFAB) with two photoelectrodes of ZnO–TiO2 heterostructure and polyterthiophene (pTTh)‐coated CuO (pTTh–CuO) grown on fluorine‐doped tin oxide (FTO) is proposed. The band structure of semiconductors and the charge‐transfer mechanism...
Carbon dots (CDs) are widely studied for years due to their unique luminescent properties and potential applications in many fields. However, aggregation‐caused quenching, monotonous emission modes, and unsustainable preparation impose restrictions on their performance and practical applications. Here, this work reports the facile synthesis of sustainable silk‐derived multimode emitting CDs with dispersed‐state...
Natural materials, such as silk, nacre, and bone, possess superior mechanical properties which are derived from their unique hierarchical structures. Individual carbon nanotubes (CNTs) are considered as one of the strongest materials. However, macroscopic CNT fibers usually have breaking strength far below that of individual CNTs. In this work, by mimicking the structure of natural silk fibers, strong...
From manufacture to disposal, the interaction of graphdiyne based nanomaterials with living organisms is inevitable and crucial. However, the cytotoxic properties of this novel carbon nanomaterial are rarely investigated, and the mechanisms behind their cytotoxicity are totally unknown. In this study, the antibacterial activity of graphdiyne (GDY) and graphdiyne oxide (GDYO) is reported. GDY is capable...
Pseudocapacitors or redox capacitors that synergize the merits of batteries and double‐layer capacitors are among the most promising candidates for high‐energy and high‐power energy storage applications. 2D transition metal carbides (MXenes), an emerging family of pseudocapacitive materials with ultrahigh rate capability and volumetric capacitance, have attracted much interest in recent years. However,...
Interfacial engineering of perovskite solar cells (PSCs) is attracting intensive attention owing to the charge transfer efficiency at an interface, which greatly influences the photovoltaic performance. This study demonstrates the modification of a TiO2 electron‐transporting layer with various amino acids, which affects charge transfer efficiency at the TiO2/CH3NH3PbI3 interface in PSC, among which...
