Developing oxygen reduction reaction (ORR) catalysts with high performance at low cost is critical for the practical application of fuel cell technology. In this work, novel Fe-N-C hybrid mulberry-like fibers (denoted as MB-CFs), which are composed of hollow mesoporous carbon spheres (HMCSs) encapsulated in N-doped carbon fiber, have been synthesized by a facile electrospinning method. These composite...
This paper reported on preparation technique, fluidity mechanism and significant characteristics of covalent nanocrystals-decorated solvent-free graphene oxide liquids (CN-GOLs), which were achieved through the introduction of nanocrystals onto the surface of graphene oxide (GO), and then by surface chemical engineering of the nanocrystals-decorated graphene oxide (N-GO) with organosilanes as corona...
We theoretically predict self-imaging induced by multi-mode interference in multi-walled carbon nanotube arrays at visible wavelengths. To obtain propagation constants of guided modes and positions of self-imaging, the dispersion relation based on a dielectric function of frequency of the designed multi-walled carbon nanotube arrays is analyzed. The field distribution of self-imaging is performed...
By taking advantage of design and construction of strong graphene–matrix interfaces, a ternary nanoparticle (GNS-Fe3O4@PZM) consisting of graphene, Fe3O4 nanoparticles and highly cross-linked polyphosphazene has been synthesized via a two-stage process consisting of co-precipitation and precipitation polymerization. And then the bismaleimide (BMI) matrix composites with aligned GNS-Fe3O4@PZM are fabricated...
In order to improve the electrochemical performance of Na/CFx cell, fluorinated multi-walled carbon nanotubes (F-MWCNTs) and a new composite consisting of CFx, graphene nanosheets (GNS) and FeF3 (labeled as CGF for short) were employed as cathode materials in rechargeable room-temperature sodium batteries for the first time. The polarizations of Na/F-MWCNTs and Na/CGF cell were found to be 1600 and...
