Study of hydrogen absorption in a novel three-dimensional graphene structure: Towards hydrogen storage applications
نویسندگان
چکیده
The use of a novel three-dimensional graphene structure allows circumventing the limitations two-dimensional nature and its application in hydrogen absorption. Here we investigate hydrogen-bonding on monolayer conformally grown via epitaxial growth method (0001) face porousified 4H-SiC wafer. Hydrogen absorption is studied Thermal Desorption Spectroscopy (TDS), exposing samples to either atomic (D) or molecular (D2) deuterium. temperature, exposure morphology are investigated related their effect structures chemically bind deuterium when exposed D2. This first report such an event unfunctionalized graphene-based materials implies presence catalytic splitting mechanism. It further shown that dendritic porous material temporarily retains desorbed molecules causes delayed emission. capability chemisorbing atoms after hydrogen, coupled large surface-to-volume ratio, make these promising substrate for storage devices.

Prospects for hydrogen storage in graphene.
Hydrogen-based fuel cells are promising solutions for the efficient and clean delivery of electricity. Since hydrogen is an energy carrier, a key step for the development of a reliable hydrogen-based technology requires solving the issue of storage and transport of hydrogen. Several proposals based on the design of advanced materials such as metal hydrides and carbon structures have been made t...

In this paper, we explore the linear response of one dimensionalquasiperiodic structure based on Fibonacci sequence composed of silicon dioxide,polystyrene and graphene materials. Here, a graphene monolayer is sandwichedbetween two adjacent layers. The numerical results are obtained by using the standardtransfer matrix method. Due to the presence of graphene sheet in eac...

متن کاملLocalised Neutral Hydrogen Absorption Towards the Radio
We present ∼ 0. ′′ 15 (56 pc) resolution MER-LIN observations of neutral hydrogen (H i) λ21 cm absorption detected towards the arcsecond-scale radio jet of the Seyfert 1.5 galaxy Markarian 6. Absorption is detected only towards a bright, compact radio feature located, in projection, ∼ 380 pc north of the likely location of the optical nucleus. Based on comparison with an archival HST image, we ...
