Porous Co₃O₄ Nanotubes Derived From Co₄(CO)₁₂ Clusters on Carbon Nanotube Templates: A Highly Efficient Material For Li‐Battery Applications

Abstract

Over the past decades, a worldwide effort has been made to search for alternative anode materials of lithium batteries for improving their energy density and safety.[1] It has been found that 3d transition metal oxides such as nickel oxide, cobalt oxide, and iron oxide exhibit reversible capacities about three times larger than those of graphite (372 mAh g -1

Evaluating the performance of nanostructured materials as lithium-ion battery electrodes

“…The porosity of Co3O4 nanowire samples has been suggested to aid the structural integrity of the material by accommodating much of the volume strain associated with the early intercalation of Li + (LixCo2O3), and the phase changes brought about during the electrochemical conversion sequence [189]. Other reported 1D Co3O4 nanostructures of note include C/Co3O4 nanowires [191], CNT-templated porous nanotubes [192], solution-grown needle-like nanotubes [193], nanoneedles [194], and nanobelts [195]. In particular, mesoporous Co3O4 nanobelts, which were prepared by the calcination of α-Co(OH)2 nanobelts, delivered high capacity and stable early cycling.…”

Carbon nanotubes/magnetite hybrids prepared by a facile synthesis process and their magnetic properties

“…With the great progress achieved in this field, CNTs have been used to synthesize not only various polymer/CNTs composites [4][5][6][7][8] but also various CNTs/metal oxide hybrids [9][10][11][12][13], where CNTs can serve as high-performance supporting materials. The decoration of CNTs with metal oxide nanoparticles can give them new properties and potentials for various applications [14][15][16][17][18].…”

Synthesis of Co3O4 nanotubes and their catalytic applications in CO oxidation

“…Among them, Co 3 O 4 nanotubes have received particular attention because of the hollow interior and the high aspect ratio [15]. To date, Co 3 O 4 nanotubes with the outer diameter in 30-300 nm range have typically been fabricated by topotactic transformation [11], hydrothermal synthesis [12], microemulsion [13] and template-directed synthesis [14]. The Kirkendall effect was also applied to prepare Co 3 O 4 nanotubes.…”

“…In recent years, great efforts have been paid to tune the shape of Co 3 O 4 nanomaterials [10][11][12][13][14][15]. Among them, Co 3 O 4 nanotubes have received particular attention because of the hollow interior and the high aspect ratio [15].…”
