Broadband infrared (IR) absorption is sought after for wide range of applications. Graphene can support IR plasmonic waves tightly bound to its surface, leading to an intensified near‐field. However, the excitation of graphene plasmonic waves usually relies on resonances. Thus, it is still difficult to directly obtain both high near‐field intensity and high absorption rate in ultra‐broad IR band....
A kind of metal–organic framework (MOF) aerogels are synthesized by the self‐assembly of uniform and monodisperse MOF nanofibers. Such MOF nanofiber aerogels as carbon precursors can effectively avoid the aggregation of nanofibers during calcination, resulting in the formation of well‐dispersed hollow porous carbon nanofibers (HPCNs). Moreover, HPCNs with well‐dispersion are investigated as sulfur...
Composite materials with multifunctional properties usually possess synergetic effects in catalysis toward cascade reactions. In this work, a facile strategy to the encapsulation of octahedral Cu2O nanocrystals (NCs) by metal–organic frameworks (MOFs) is reported, and an oriented growth of MOF enclosures (namely, HKUST‐1) around Cu2O NCs with desired feedstock ratio is achieved. The strategy defines...
The surface reconstruction of oxygen evolution reaction (OER) catalysts has been proven favorable for enhancing its catalytic activity. However, what is the active site and how to promote the active species generation remain unclear and are still under debate. Here, the in situ synthesis of CoNi incorporated Fe3N nanotubes (CoNi–Fe3N) on the iron foil through the anodization/electrodeposition/nitridation...
Porous nanostructured materials are demonstrated to be very promising in catalysis due to their well accessible active sites. Thermally stable metal‐organic frameworks (MOFs) as hard templates are successfully utilized to afford porous metal oxides and subsequently metal sulfides by a nanocasting method. The resultant metal oxides/sulfides show considerable Brunauer–Emmett–Teller (BET) surface areas,...
