High temperature annealing effects on carbon spheres and their applications as anode materials in Li-ion secondary battery

Synthesis of uniform and size-controllable carbon nanospheres by a simple hydrothermal method and fabrication of carbon nanosphere super-hydrophobic surface

“…4(d)) or at higher temperatures and longer times led to some morphologies like polyhedrons with rough surfaces. Existence of such morphologies is consistent with those reported by Huang and Kroto [2,10]. In order to understand the CS size reduction mechanism, it is necessary to consider the microstructure of CNSs that is explained and showed elsewhere [2,10,11].…”

“…Existence of such morphologies is consistent with those reported by Huang and Kroto [2,10]. In order to understand the CS size reduction mechanism, it is necessary to consider the microstructure of CNSs that is explained and showed elsewhere [2,10,11]. From those reports and the discussions in Section 3.1, one can conclude that every CNSs is constructed of too many two-dimensional graphitic curved and small flaks compacted over each other with an interlayer distance of about 3-4Å.…”

“…Recently, carbon nano-and microspheres have attracted great attention due to their wide range applications such as electrode for supercapacitors, anode in secondary lithium batteries, material reinforcement, templates for hollow structures, capsules for magnetic nanoparticles, refinement of aqueous solutions, catalyst for direct methanol fuel cells, etc. [1][2][3][4][5][6].…”

CVD synthesis of carbon spheres using NiFe-LDHs as catalytic precursors: structural, electrochemical and magnetoresistive properties

“…Furthermore, their unclosed graphitic flakes give rise to dangling bonds throughout the surface of the spheres, increasing their reactivity and boosting their applicability in adsorption, lubricants, tribological coatings, catalysis, batteries, supercapacitors or fuel cells among others. [10][11][12][13][14][15] Conversely, when it comes to their transport and magnetic properties, the list of examples is very scarce, 16,17 despite their potential for use as electronically active reinforcing agents of functional composites. 18,19 Indeed, the recent discovery of organic magnetoresistance (OMAR) in graphene and other related nanocarbons has significantly attracted increasing attention to these systems, as they are promising materials for flexible, low-cost and transparent electronics.…”

Electrochemical and photo-electrochemical properties of carbon spheres prepared via chemical vapor deposition

“…Many different types of carbon spheres with different morphologies and sizes have been prepared through different processes using various carbon containing reagents as precursors [8][9][10][11][12][13][14][15][16].…”
