Requirements for nanoparticle processing based on energy and cost-effective technologies have increased in recent years. Flame synthesis is widely used on an industrial scale and is superior to gas phase one-step processes for producing nanoparticles; however, further improvements are required from the viewpoint of energy efficiency. In this work, we present a new aerodynamically stable nanoparticle processing method with extremely low energy losses, based on the use of a tubular flame. The developed tubular flame apparatus is inexpensive and simple to set up, allowing for a uniform and high temperature field with a high energy efficiency. Consequently, highly crystalline and uniform WO₃ nanoparticles were successfully synthesized with a high production rate. The simple and energy-effective process proposed in this work has potential for application to various types of functional nanoparticle production.

管状火焰燃烧用于纳米粒子生产

近年来，对基于能量和具有成本效益的技术的纳米颗粒处理的需求不断增加。火焰合成在工业规模上被广泛使用，并且优于用于生产纳米颗粒的气相一步法。但是，从能量效率的观点出发，还需要进一步的改进。在这项工作中，我们基于管状火焰，提出了一种具有极低能量损失的新型空气动力学稳定的纳米颗粒加工方法。所开发的管状火焰设备便宜且易于安装，从而允许具有高能量效率的均匀且高温的场。因此，高度结晶且均匀的WO ₃以高生产率成功地合成了纳米颗粒。在这项工作中提出的简单而节能的方法具有应用于各种类型的功能纳米颗粒生产的潜力。
