摘要:

納米材料的氣相燃燒合成一般是指利用氣體燃料燃燒提供高溫，通過物理或者化學(xué)過程從氣溶膠中獲得納米材料的過程。氣相燃燒法可以制備不同結(jié)構(gòu)的納米材料，具有過程連續(xù)、易于規(guī)�；�、無后處理、低成本等優(yōu)點，是納米材料制備最具工業(yè)化潛力的方法之一。氣相燃燒制備納米材料涉及快速高溫反應(yīng)和產(chǎn)物單體成核、生長、凝并、團聚等過程，這些過程互相關(guān)聯(lián)、交互影響；納米材料制備過程中材料結(jié)構(gòu)調(diào)控及材料生長機理成為近年來國內(nèi)外的研究重點。主要介紹了氣相燃燒反應(yīng)器結(jié)構(gòu)、材料制備、結(jié)構(gòu)調(diào)控、應(yīng)用性能和工業(yè)生產(chǎn)等方面的研究進展，并對其前景進行了展望。

Abstract:

The gas combustion flame technology refers to the formation of nanomaterials from gases in flames. Flame synthesis which has many advantages, such as continuous, scalable, without post�瞭reatment, low cost and large quantities, has become an established way to produce nanomaterials with desired characteristics on an industrial scale. The flame aerosol synthesis for the nanoparticles involves the following processes such as rapid high�瞭emperature vapor reaction, the nucleation, growth, agglomeration, and so on. Meanwhile these processes correlate and interact, which making complex for the formation of nanomaterials. Therefore, the study of the preparation of nanoparticles and the corresponding growth mechanism in this complex flame environment has become the research emphasis in recent years. In this paper, we mainly introduced flame reactor, material preparation, structure control, application filed and commercial process base on flame aerosol process, and to explore its possible development in the future.
