Abstract Aerosol spray coupled with high-temperature pyrolysis is an emerging technique for continuous manufacturing of nanomaterials at large scale that demonstrates extremely high production efficiency. Current aerosol spray techniques using a tube furnace can only attain a low temperature range (generally 95%), during which salt decomposition and particle nucleation/growth occur. The high temperature critically enables homogeneous mixing of elements in the resultant nanoparticles and the short residence time is key to suppress particle growth and agglomeration. Compared with the traditional aerosol spray pyrolysis, the carbonized wood reactor can achieve a record high temperature (≥2000 K), a much shorter residence time (∼tens of milliseconds), highly efficient, uniform heating, and provide a platform for continuous nanomaterial manufacturing for a broad range of applications.

连续 2000 K 液滴到粒子合成

摘要 气溶胶喷雾结合高温热解是一种新兴的大规模纳米材料连续制造技术，具有极高的生产效率。目前使用管式炉的气溶胶喷雾技术只能达到较低的温度范围（通常为 95%），在此期间会发生盐分解和颗粒成核/生长。高温至关重要地使所得纳米颗粒中的元素均匀混合，而较短的停留时间是抑制颗粒生长和团聚的关键。与传统的气溶胶喷雾热解相比，炭化木反应器可以达到创纪录的高温（≥2000 K），更短的停留时间（~几十毫秒），高效，加热均匀，
