现代火焰气溶胶纳米颗粒合成是一个快速变化的领域：虽然在过去的几十年里主要生产简单的氧化物商品，如二氧化硅或二氧化钛，但对该过程的更深入了解现在允许生产具有高功能的更复杂的产品。早期颗粒形成和生长的过程模拟和诊断的进步促进了这一发展。这在非均相催化剂的合成中得到了说明，其中干焰技术可用于生产高活性纳米颗粒。通过这种方式，可以生产出形态和成分受到严格控制的无机亚微米颗粒，从而产生一系列由湿化学主导多年的新产品或新工艺。(C) 2002 Elsevier Science B.V.版权所有
Modem flame aerosol synthesis of nanoparticles is a rapidly changing terrain: While producing mainly simple oxide commodities such as silica or titania in the last few decades, a deeper understanding of the process allows now the production of more sophisticated products with high functionality. Advances in process simulation and diagnostics of early particle formation and growth contributed to this development. This is illustrated in the synthesis of heterogeneous catalysts, where dry flame technology can be used to produce highly active nanoparticles. That way, inorganic submicron particles with closely controlled morphology and composition are produced, giving rise to a series of new products or processes that have been dominated by wet chemistry for years.
