Boron magnesium co-doped VO2 powder, preparation method and application thereof

The invention discloses a boron magnesium co-doped VO2 powder, a preparation method and an application thereof. The preparation method comprises the following steps: dissolving a magnesium source anda boron source into hydrogen peroxide, and then adding a vanadium source, thereby preparing a V5+ complex hydrogel containing B3+ and Mg2+; adding a reducing agent into the V5+ complex hydrogel for performing reduction reaction, thereby acquiring a blue V4+ precursor solution; performing hydrothermal reaction on the V4+ precursor solution till generating sediment, cleaning and drying sediment, thereby acquiring an initial VO2 powder; calcining the initial VO2 powder under a protective gas atmosphere, thereby acquiring the boron magnesium co-doped VO2 powder. The invention can solve the problemof the prior art that a VO2 material with both low phase-transition temperature and high visible light transmittance cannot be acquired. 本发明公开了种硼镁共掺杂VO粉体及其制备方法和应用，其中，所述方法包括步骤：将镁源及硼源溶于双氧水中，再加入钒源，配制成含B和Mg的V配合物水凝胶；向V配合物水凝胶中加入还原剂
