Production of oxygen-deficient tungsten oxide nanoparticles with a diameter of around 10 nm have been successfully developed using a microwave-induced plasma in liquid technique. The prepared blue-green nanoparticles exhibit strong absorption in the visible region; thus, these could be efficient visible-light photocatalysts. The high-angle annular dark-field images revealed the dislocation of tungsten, which causes oxygen deficiencies.
利用液体中的微波诱导等离子体技术，已成功制备出直径约为10纳米的缺氧氧化钨纳米颗粒。制备出的蓝绿色纳米颗粒在可见光区域表现出强烈的吸收；因此，这些颗粒可能是高效的可见光光催化剂。高角度环形暗场图像揭示了钨的位错，这会导致氧缺陷。
