HIGH PRODUCTION RATE SYNTHESIS OF CDS NANOPARTICLES USING A REVERSE OSCILLATORY FLOW METHOD

摘要

A reverse oscillatory flow (ROF) mixing system is discussed having a reaction channel 460 ^m high by 152 mm wide for high flow rate processing of nanoparticle chemistries. The ROF system is demonstrated to produce CdS nanoparticles at a production rate of 115.7 g/hour with a coefficient of variation for particle size down to 19%. These production rates are substantially higher than those achieved using other microchannel mixers while maintaining comparable size distributions. Advantages of the ROF approach include the use of larger microchannels which make the reactor easier to fabricate and less vulnerable to clogging.
