“…Therefore, holey graphene has a band gap without much of compromising electrical conductivity and other properties of graphene [ 53 ]. Holey graphene does outperform graphene in some applications such as supercapacitors [ 50 ], batteries [ 71 ], water desalination [ 72 ], bioseparation, fuel cell [ 73 ], hydrogen storage [ 74 ] etc. The 3D graphene/3D graphene composites do have a band gap and outshine the holey graphene in terms of performance in certain application.…”

In the last decade, carbon-based nanostructures such as buckyball (C 60), carbon nanotube (CNT), graphene and three-dimensional (3D) graphene have been identified as promising materials for electronic, electrochemical energy storage (batteries and supercapacitors), optical and sensing applications. Since the discovery of graphene in 2004, scientists have devised mass production techniques and explored graphene as a promising material for a wide range of applications. Most of the electronic and solar cell applications require materials with good electronic conductivity, mobility and finite bandgap. Graphene is a zero bandgap material which prevents it from the mainstream applications. On the other hand, 3D graphene has good electronic conductivity, mobility, bandgap and electrochemical properties. This review article will focus on the synthesis of the 3D graphene, its structure-property relationships, biotechnology and electronic applications and the hidden properties that are yet to be explored fully.

“…Motivated by this consideration, researchers have focused on various nanostructured materials, including two-dimensional (2D) sheets (boron-based nanomaterials, graphene-like nanomaterials, MXenes, MoS 2 , CxNy, etc.) [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ], metal atom-modified covalent organic frameworks (COFs) [ 14 , 15 , 16 ], and metal organic frameworks (MOFs) [ 17 , 18 , 19 , 20 , 21 ]. These materials can exhibit significantly improved kinetics during the adsorption process by decreasing the enthalpy of formation and hydrogenation temperature, and they exhibit many other catalytic effects [ 22 , 23 , 24 ].…”

Reversible Hydrogen Storage Media by g-CN Monolayer Decorated with NLi4: A First-Principles Study

et al. 2023

A two-dimensional graphene-like carbon nitride (g-CN) monolayer decorated with the superatomic cluster NLi4 was studied for reversible hydrogen storage by first-principles calculations. Molecular dynamics simulations show that the g-CN monolayer has good thermal stability at room temperature. The NLi4 is firmly anchored on the g-CN monolayer with a binding energy of −6.35 eV. Electronic charges are transferred from the Li atoms of NLi4 to the g-CN monolayer, mainly due to the hybridization of Li(2s), C(2p), and N(2p) orbitals. Consequently, a spatial local electrostatic field is formed around NLi4, leading to polarization of the adsorbed hydrogen molecules and further enhancing the electrostatic interactions between the Li atoms and hydrogen. Each NLi4 can adsorb nine hydrogen molecules with average adsorption energies between −0.152 eV/H2 and −0.237 eV/H2. This range is within the reversible hydrogen storage energy window. Moreover, the highest achieved gravimetric capacity is up to 9.2 wt%, which is superior to the 5.5 wt% target set by the U.S. Department of Energy. This study shows that g-CN monolayers decorated with NLi4 are a good candidate for reversible hydrogen storage.

“…However, there are serious issues with these substrate materials, such as high desorption temperature for metal hydrides, lower hydrogen uptake for zeolites, instability at high temperatures, clustering of the metal atoms, etc. Metal doped carbon nanomaterials such as fullerenes [8,[21][22][23][24], carbon nanotubes [25][26][27][28][29][30][31][32][33][34], graphene [35][36][37][38][39], graphyne [40][41][42][43], advanced 2d materials [44][45][46][47] have also been studied widely for hydrogen storage due to their low molecular mass and high surface area. Pristine carbon nanomaterials are not suitable for hydrogen storage as they bind the hydrogen molecules only by the weak van der Waals forces at ambient conditions [48,49], hence desorption temperature is lower than the room temperature.…”
