Gas permeation through graphdiyne-based nanoporous membranes

Graphdiyne (GDY), a rising star of carbon allotropes, features a two-dimensional all-carbon network with the cohybridization of sp and sp 2 carbon atoms and represents a trend and research direction in the development of carbon materials. The sp/sp 2 -hybridized structure of GDY endows it with numerous advantages and advancements in controlled growth, assembly, and performance tuning, and many studies have shown that GDY has been a key material for innovation and development in the fields of catalysis, energy, photoelectric conversion, mode conversion and transformation of electronic devices, detectors, life sciences, etc. In the past ten years, the fundamental scientific issues related to GDY have been understood, showing differences from traditional carbon materials in controlled growth, chemical and physical properties and mechanisms, and attracting extensive attention from many scientists. GDY has gradually developed into one of the frontiers of chemistry and materials science, and has entered the rapid development period, producing large numbers of fundamental and applied research achievements in the fundamental and applied research of carbon materials. For the exploration of frontier scientific concepts and phenomena in carbon science research, there is great potential to promote progress in the fields of energy, catalysis, intelligent information, optoelectronics, and life sciences. In this review, the growth, self-assembly method, aggregation structure, chemical modification, and doping of GDY are shown, and the theoretical calculation and simulation and fundamental properties of GDY are also fully introduced. In particular, the applications of GDY and its formed aggregates in catalysis, energy storage, photoelectronic, biomedicine, environmental science, life science, detectors, and material separation are introduced.

Carbon allotropes have contributed to all aspects of people’s lives throughout human history. As emerging carbon-based low-dimensional materials, graphyne family members (GYF), represented by graphdiyne, have a wide range potential applications due to their superior physical and chemical properties. In particular, graphdiyne (GDY), as the leader of the graphyne family, has been practically applied to various research fields since it was first successfully synthesized. GYF have a large surface area, both sp and sp2 hybridization, and a certain band gap, which was considered to originate from the overlap of carbon 2p z orbitals and the inhomogeneous π-bonds of carbon atoms in different hybridization forms. These properties mean GYF-based materials still have many potential applications to be developed, especially in energy storage and catalytic utilization. Since most of the GYF have yet to be synthesized and applications of successfully synthesized GYF have not been developed for a long time, theoretical results in various application fields should be shared to experimentalists to attract more intentions. In this Review, we summarized and discussed the synthesis, structural properties, and applications of GYF-based materials from the theoretical insights, hoping to provide different viewpoints and comments.

Graphdiine (engl. graphdiynes=GDYs) sind zweidimensionale graphenähnliche Kohlenstoffsysteme und gelten aufgrund ihrer einzigartigen physikalisch‐chemischen Eigenschaften als potenzielles Membranmaterial. Die Maßstabvergrößerung der Präparation von GDY‐Membranen ist jedoch eine technologische Herausforderung. Wir berichten hier über eine einfache und effiziente alkinierte oberflächenvermittelte Strategie zur Herstellung von wasserstoffsubstituierten Graphdiin[1c] (HsGDY)‐Membranen auf kommerziellen Aluminiumoxidrohren, die zuvor Alkin‐modifiziert wurden. Die Oberflächenalkinierung der Keramik erlaubt eine oberflächenbegrenzte Kupplungsreaktion in Gegenwart eines Kupferkatalysators und ermöglicht so das epitaktische Wachstum von HsGDY im Nanomaßstab. Eine kontinuierliche und ultradünne HsGDY‐Membran (∼100 nm) kann innerhalb von 15 min hergestellt werden. Die resultierenden Membranen weisen eine sehr hohe Molekularsiebung zusammen mit hervorragender Wasserpermeanz (ca. 1100 L m−2 h−1 MPa−1) auf und zeigen aufgrund der superhydrophilen Oberfläche und hydrophoben Porenwände ein stabiles Trennverhalten in der Cross‐Flow‐Nanofiltration.
