摘要： The present invention provides a metal/metal oxide doped-WO3 flower-like assemblies as a photocatalyst applied to photocatalytic inactivation of influenza virus and bacteria under UV or visible light activation, and further provides a surface-modulator-driven synthesis method for producing WO3 flower-like assemblies, as well as doping methods for doping the metal/metal oxide to the WO3 flower-like assemblies. The metal/metal oxide doped in WO3 flower-like assemblies can further enhance the antiviral and antibacterial performances.

摘要： Chemically and mechanically protective oxide film was formed on Mg alloys using micro-arc oxidation (MAO) methods. Further modification of the obtained MAO surfaces was made in various aspects and the processes thereof were described. Firstly, the protection is enhanced by forming super-hydrophobic surfaces, with water contact angle higher than 140°, attributed to hierarchical nano-micro structures. Secondly, the electrical property of the MAO surfaces is modified. A film with sheet resistance as low as 0.05 Ω/sq is achieved by electro-less Ni deposition on MAO surfaces. Thirdly, black colors are achieved by the sol-gel process on MAO samples.

摘要： A plasma driven catalyst apparatus useful for disinfecting and purifying air. The apparatus has a synergistically favorable effect from plasma and catalyst on high disinfecting and purifying efficiency and efficacy, low by-product formation, and low energy consumption. The plasma combined with catalyst enhances the production of new reactive species, increases the oxidizing power of the plasma discharge, as well as activate the catalyst that additionally contributes towards the disinfection and purification process and the elimination of toxic by-products.
