Monocrystalline VO2(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 VO2(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 VO2(B). A hydrating-exfoliating-splitting mechanism was established to explain the formation of the nanoplate architecture. The synthesized VO2(A) nanoplates showed outstanding peroxidase-like activity and hence are a promising candidate for artificial peroxidase.
