Graphene-like nanostructures: synthesis and use for preparation of catalysts and hydrogen storage composites

Experimental and density functional theory studies of laminar double-oxidized graphene oxide nanofiltration membranes

“…Although the separation performance of GO membranes reported in the present work has been optimized only by changing the oxidation level of GO nanosheets, their separation behavior is more favorable than many reported membranes. For HGOM, considering the trade-off of water flux and rejection for NF membranes, reaching 230 L/(m 2 .h) water flux with 99.9% rejection (2.5 bar pressure) is excellent (Zhang et al, 2020b;Zhu et al, 2020b;Arbuzov et al, 2016;Kong et al, 2019). The high water flux of HGOM was attributed to the increased interlayer spacing of HGO nanosheets due to the higher level of oxidation, confirmed by the XRD patterns shown in Fig.…”

Graphene Supports for Metal Hydride and Energy Storage Applications

“…100 • C). Some of these shortcomings can be alleviated by the inclusion of the active hydrogen-storing compound in a nanoporous matrix such as graphene [12]. Graphene is a 2D material with very appealing properties, highlighting its potential use as support for various reactive species, including metals and metal hydrides [13].…”

Nickel-Graphene Nanostructures: Synthesis, Study and Applications

“…Until now numerous studies have considered graphene and graphene-like materials (GLM) as promising carriers of nanosized metal and metal oxide catalysts to be used for the development of and functional catalytic composites. [1] GLM have layered structure of sp 2 hybridized carbon atoms arranged in a two-dimensional hexagonal lattice. [2] The most promising techniques for the formation of metal-containing graphene composites include simultaneous reduction of graphite oxide and growth of metal nanoparticles.…”
