“…In this work, we focus on the performance of the hierarchically stacked Gr-CNT structure, rather than proposing the direct use of our Gr-CNT composite as an anode in the actual case. Such vertically periodical -Gr-CNT-Gr-CNT-structure combined with single-layered graphene and short CNT is hard to fabricate on a large scale now, but the Gr-CNT fragment already experimentally exists in the interface between multilayer graphite and CNTs [14,15,48] and also exists in porous graphene [49][50][51] and amorphous carbons. [52,53] With the van der Waals interaction, pristine CNTs tend to accumulate, which affects their performance as anode.…”

A thermodynamically and kinetically stable 3D hierarchical carbonaceous nanostructure is constructed to examine its potential as an anode for sodium-ion batteries (SIBs). Heptagonal and quadrilateral staggered carbon rings are formed where the graphite layers and the CNT interconnect vertically. Based on first-principles calculations, such a graphite-CNT hybrid with expanded interlayer spacing allows effective binding to Na atoms and contributes a high specific capacity of 324.3 mAh g −1 . It maintains a great electronic conductivity for both pristine and Na-adsorbed graphite-CNT along the expanded graphite layers, and constructs a 3D electronic transport network when a large number of Na atoms are adsorbed. This hierarchical nanostructure predicts a fast inner 3D Na-ion transport network, with energy barriers of 0.56 and 0.50 eV along the expanded graphite layer and the CNT channel, respectively. This research manifests the feasibility of obtaining well-performed graphite-based anodes for SIBs through purposeful microcosmic morphology modification.

Graphene is the main allotropy of carbon which exhibits properties like super conductivity, high electron transfer, and large surface area. Porous graphene (PG) has unique porous structure and many exposed edges. In 2D graphene pore ranges from several angstroms to nanometers. Similar to 3D graphene, which also has a porous structure, there are four different types: foam, sponge, and graphene hydrogel (GH). Graphene oxide (GO) and reduced graphene oxide (rGO) are used to create PG. This review focuses on various methods of synthesis of PG along with its inherent properties and methods to modify its properties by surface functionalization. Emphasis is also given on the discussion of various techniques that are involved in the PG characterization. This article discusses the formation of hybrids, and composites using PG. Applications and limitations of PG have also been indicated. This review shows an extensive overview of the main principles and the recent synthetic technologies about fabricating various innovative 3D graphene‐based materials. Subsequently, recent progresses in electrochemical energy devices and hydrogen energy generation/storage are explicitly covered. The applications of PG and its composites in the fields such as energy storage, solar units, sensors, supercapacitors, etc. have been discussed The up to date progress for pollutants detection and environmental remediation are also reviewed. Finally, challenges and outlooks in materials development for different applications are suggested.

Sodium‐ion batteries are considered one of the most promising candidates for affordable and scalable energy storage as required in smart grid and renewable energy. One of the principal challenges sodium‐ion batteries being faced is to search suitable anode materials that can accommodate and store large amounts of Na+ ions reversibly and sustainably at reasonable galvanostatic rates. Molybdenum‐based materials such as oxides and sulfides might meet this challenge as they afford a capacity much greater than those of the carbonaceous materials and exhibit rich Na‐reaction chemistry. However, these materials are facing several technical issues, such as multiple‐phase transformation, particle pulverization as the result of volume swelling, and low surface activity during sodiation/desodiation. To tackle these issues, materials design and engineering are of indispensability. In this brief review, we present a state‐of‐the‐art overview of the research progress of molybdenum‐based materials for sodium storage, and highlight materials engineering strategies that are capable of addressing the mentioned challenges. We also offer valuable insights into their further development direction and discuss their potentiality in practical batteries.
