“…Table 4 summarize some typical published papers of VO 2 (A), which demonstrates VO 2 (A) does not have rich morphologies as VO 2 (B), and nanorod, nanobelt, or nanowire are the common shapes . Such one‐dimensional nanostructures possess excellent surface activities and have short Li‐ion insertion/extraction distances, which is beneficial for electrochemical batteries . Due to the structure phase‐transition, VO 2 (A) also displays a thermochromic property.…”

Vanadium dioxide (VO ) is a widely studied inorganic phase change material, which has a reversible phase transition from semiconducting monoclinic to metallic rutile phase at a critical temperature of τ ≈ 68 °C. The abrupt decrease of infrared transmittance in the metallic phase makes VO a potential candidate for thermochromic energy efficient windows to cut down building energy consumption. However, there are three long-standing issues that hindered its application in energy efficient windows: high τ , low luminous transmittance (T ), and undesirable solar modulation ability (ΔT ). Many approaches, including nano-thermochromism, porous films, biomimetic surface reconstruction, gridded structures, antireflective overcoatings, etc, have been proposed to tackle these issues. The first approach-nano-thermochromism-which is to integrate VO nanoparticles in a transparent matrix, outperforms the rest; while the thermochromic performance is determined by particle size, stoichiometry, and crystallinity. A hydrothermal method is the most common method to fabricate high-quality VO nanoparticles, and has its own advantages of large-scale synthesis and precise phase control of VO . This Review focuses on hydrothermal synthesis, physical properties of VO polymorphs, and their transformation to thermochromic VO (M), and discusses the advantages, challenges, and prospects of VO (M) in energy-efficient smart windows application.

“…Meanwhile, the transformation from VO 2 (A) to VO 2 (M) face the same issues as that of VO 2 (B), such as the high annealing temperature and resultant coarsening of VO 2 (M). Researches on VO 2 (A) are mainly concentrate on its structure phase transition and electrochemical properties …”

“…As a consequence, VO 2 (M) has been recently extensively studied with the aim of developing novel sensors and switching devices. [13][14][15][16] The studies showed that VO 2 (A) undergoes a reversible structural phase transition at around 435 K and is probably used as cathode, electron emission, and optical switch materials. [8][9][10] Nevertheless, presently VO 2 (A) has been received much less attention compared with VO 2 (M), although a comprehensive study of VO 2 (A) phase transition is scientically important to understand the exact physical mechanism of the rst-order structural phase transition which has been debated for decades.…”

Structural transition and temperature-driven conductivity switching of single crystalline VO₂(A) nanowires

et al. 2014

Single crystalline VO 2 (A) nanowires were synthesized by a facile hydrothermal method. The structural transition and temperature-driven conductivity switching of the VO 2 (A) nanowires were investigated. Our experimental results show that VO 2 (A) nanowires exhibit a distinct structural transition accompanied with an order of magnitude change in resistance, and a clear temperature-dependent current switching hysteresis. In order to analyze experimental results, theoretically, the electrical conductivity behavior was found to be consistent with Mott's small polaron model, the first-principles calculations also indicated that the apical V-O bond changes were mainly responsible for the band gap evolution and hence led to the conductivity switching.

“…25 In addition, Dai et al prepared 1D VO 2 (A) nanostructures via a one-step hydrothermal method using VOSO 4 and NH 3 $H 2 O as precursors; the prepared material was used as a high performance cathode in LIBs. 26 Much effort has been put into developing synthetic strategies for the fabrication of VO 2 nanostructures, using methods such as sol-gel, templating, ion implantation, precursor pyrolysis, hydrothermal and solvothermal syntheses, magnetron sputtering and gas-phase deposition. [27][28][29][30][31] These methods generally produced VO 2 (R) or VO 2 (B), but the metastable VO 2 (A) was only obtained by the hydrothermal method.…”

Monocrystalline VO 2 (A) nanoplates have been synthesized via a one-pot hydrothermal process. In situ powder X-ray diffraction was used to monitor the hydrothermal synthesis and it was found that VO 2 (A) nucleates and grows directly from solution after the complete hydrolysis of a 2.0 M VO(acac) 2 precursor solution, rather than involving a previously reported intermediate phase VO 2 (B). A hydrating-exfoliatingsplitting mechanism was established to explain the formation of the nanoplate architecture. The synthesized VO 2 (A) nanoplates showed outstanding peroxidase-like activity and hence are a promising candidate for artificial peroxidase.
