提出了一种常压等离子体增强纳米颗粒合成（APPENS）工艺，用于制备钛基可见光催化剂。将四异丙醇钛（TTIP）前驱体用N2载气气化，进入非热交流等离子体系统。利用等离子体能量将氮气解离成N原子，然后将其掺杂到前驱体蒸气中。制备的TiO2-xNx纳米颗粒具有高度均匀性和可调节的尺寸。钛基颗粒的粒径范围为25 ~ 40 nm，其大小取决于TTIP/H2O的前驱体比。除了生产光催化颗粒外，apaps工艺还具有作为连续流动纳米级单分散气溶胶发生器的潜在应用。
An atmospheric pressure plasma-enhanced nanoparticle synthesis (APPENS) process was proposed to produce a titania-based visible light photocatalyst. The titanium tetraisopropoxide (TTIP) precursor was vaporized with a N2 carrier gas and entered a nonthermal AC plasma system. The N2 gas was dissociated into N atoms by the plasma energy, and then they were doped into the precursor vapors. The produced TiO2-xNx nanoparticles were highly uniform and adjustable in size. The titania-based particle sizes ranged from 25 to 40 nm, and they depended on the precursor ratio of TTIP/H2O. In addition to producing the photocatalytic particles, the APPENS process has a potential application as a continuous-flow nanosize monodisperse aerosol generator.
