Polymer assisted approach to two-dimensional (2D) nanosheets of B4C

Large-Scale Synthesis of Graphene-Like MoSe2 Nanosheets for Efficient Hydrogen Evolution Reaction

“…Two-dimensional (2D) materials have attracted great attention of researchers due to their fascinating properties and promising applications. − As known to all, graphene has extraordinary properties, such as optical, electronic, thermal, and mechanical properties together with a superior surface area, which offers great benefits when they are used in transistors and as electrochemical electrodes . However, their switch current ability in transistors is seriously reduced because of the zero band gap of pristine graphene .…”

Microstructure and microwave‐absorbing properties of B4C/C composite powders produced by combustion synthesis with an AC foaming agent

“…Among the existing dielectric loss ceramic materials, B 4 C exhibits remarkable potential as a P-type semiconductor with a relatively narrow energy band gap (2.09 eV), which brings a tunable conductivity and higher dielectric loss capacity owing to the easier electronic transition, and also with a low density (2.52 g/cm 3 ), a high hardness (29.1 GPa), and a high melting point (2450 • C) that lead to prominent thermostability, antioxidation, and noncorrosion. 9,10 To develop its microwave-absorbing properties, B 4 C/C composite powders are synthetized with novel morphologies comprising nuclear-shell, nanoparticle, nanowire, nanosheet, and porous structure in the recent studies, such as the B 4 C@GN nanosheets, which were prepared by a molten salt-mediated carbothermal reduction method 11 ; the ACF@B 4 C hybrid nanowires, which were prepared via an in situ thermal growth method 12 ; and the C-encapsulated B 4 C (B 4 C@C) nanoparticles, which were prepared via a sol-gel route. 13 Consequently, it is obvious that the higher conductivity, diverse composition, and various microstructures create more efficient microwave-absorbing properties owing to the improved conductive network and enhanced polarization.…”

Exploring the feasibility of a two-dimensional layered cobalt-based coordination polymer for supercapacitor applications: effect of electrolytic cations

“…Over the past few years, graphene and other 2D materials such as MXenes, 21,22 2D covalent organic frameworks (COFs), 23 B 4 C, 24 C 3 N 4 , 25 2D coordination polymers (CPs) 26 and layered metal oxides/hydroxides 27,28 have been highly explored as supercapacitor materials. Among these materials, CPs have properties like tunable porosity, extensive surface area, and their flexibility to host a number of guest molecules and are attractive materials to be utilized for supercapacitor application.…”
