Structurally optimized transition metal phosphides are identified as a promising avenue for the commercialization of lithium–sulfur (Li–S) batteries. In this study, a CoP nanoparticle‐doped hollow ordered mesoporous carbon sphere (CoP‐OMCS) is developed as a S host with a “Confinement–Adsorption–Catalysis” triple effect for Li–S batteries. The Li‐S batteries with CoP‐OMCS/S cathode demonstrate excellent...
Achieving strong adsorption and catalytic ability toward polar lithium polysulfide species (LiPSs) of the sulfur host in lithium–sulfur (Li–S) batteries is essential for their electrochemical cyclic stability. Herein, a strategy of “self‐termination of ion exchange” is put forward to synthesize the novel yolk‐shell sulfur host composed of ZnO nanoparticles confined in Co‐doped NiO (CDN) polyhedron...
Metal–organic frameworks (MOFs) have attracted enormous research interest as precursors/templates to prepare catalytic materials. However, the effect of structural isomerism of MOFs on the catalytic performance has rarely been studied. In this contribution, two topologically different Ce‐benzene tricarboxylate (Ce‐BTC) based on the same ligands and metal centers (viz., “MOF isomers”) are prepared...
A new family of single‐atom‐thick 2D germanium‐based materials with graphene‐like atomic arrangement, germanene and functionalized germanene, has attracted intensive attention due to their large bandgap and easily tailored electronic properties. Unlike carbon atoms in graphene, germanium atoms tend to adopt mixed sp2/sp3 hybridization in germanene, which makes it chemically active on the surface and...
Catalytic nanomaterials can be used extrinsically to combat diseases associated with a surplus of reactive oxygen species (ROS). Rational design of surface morphologies and appropriate doping can substantially improve the catalytic performances. In this work, a class of hollow polyvinyl pyrrolidone‐protected PtPdRh nanocubes with enhanced catalytic activities for in vivo free radical scavenging is...
A simple method to prepare metal‐organic framework (MOF) nanotubes is developed by employing polyoxometalates (POMs) as modulators. The local structure of the MOF nanotubes is investigated combining XANES and EXAFS studies. These nanotubes show both an excellent catalytic performance in the detoxification of sulfur compounds in O2 atmosphere and a remarkable cycling stability as the anode material...
