Finally, three design strategies were proposed to boost the Kr/Xe separation performance of MOFMs. Combining HTCS, ML and MF, we provide a new direction for designing high-performance MOFMs for Kr/Xe separation. 展开 关键词: Kr/Xe Metal–organic framework membrane Separation Machine learning ...
most SC–MOFs still show moderate magnetism because the spin coupling of metal ions is constrained within the MOF structure, and the presence of large–size ligands promotes the establishment of random spin arrangements23. As a result, SC–MOFs are highly susceptible to an imbalance in magnetoelect...
2D MOF nanosheets have several advantages, such as high purity, ultrathin layer thickness, well refined surface area, abundant exposed unsaturated metal sites, and adjustable chemical composition compared with their 3D counterpart [97]. The drug-loading capacity of 2D MOF nanosheets make them benefici...
Membranes could reform the field of molecular separations by enabling new low energy manufacturing technologies. This review article discusses the current state of the art and the potential in the 2D-enabled membrane separation processes by highlighting
structure of the MOF remained intact within the NiDOBDC/GO composites. Moreover, the aggregation of NiDOBDC nanocrystals was inhibited, which enhanced the overall gas storage capacity of the 2D–3D nanocomposite. Various mixed-dimensional nanocomposites for H2storage and CO2capture...
Since their seminal discovery in 2011, two-dimensional (2D) transition metal carbides/nitrides known as MXenes, that constitute a large family of 2D materials, have been targeted toward various applications due to their outstanding electronic properties. MXenes functioning as co-catalyst in combination...
Highly dense 2D MoS2 fin-like nanostructures on carbon nanospheres were fabricated and formed the main catalyst support structure in the oxygen reduction reaction (ORR) for polymer electrolyte membrane (PEM) fuel cells. These nanofins were observed growi
