Thermal plasma technology is a high technology area which fits perfectly with Quebec's enviable position in abundant hydroelectric energy. Thermal plasmas are a highly effective way of producing nanoparticles (metallic, ceramic and intermetallic) and we have demonstrated their use in several systems (Ni, Cu, Al, SiO2, TiN). In the present proposal we will focus on the synthesis of ceramic nanoparticles in two competing systemc (transferred arc and induction coupled plasmas) to allow an assessment to be made of the most promising technology. Specifically we will study the synthesis of stable nanosized titania stabilized with silica. The challenge is to maintain the high photocatalytic activity of this material while applying it in relatively high temperature systems. As in our previous work, the major focus is on reactor design and scale up. Industrial production requires powers of hundreds of kW to MW while most experimental work has been at the sub 50 kW scale. We will build on past modelling and experimental work.

热等离子体技术是一个高科技领域，非常适合魁北克在丰富的水力发电中令人羡慕的位置。热等离子体是生产纳米颗粒（金属，陶瓷和金属间）的高效方法，我们已经证明了它们在多种系统中的使用（Ni，Cu，al，Al，Sio2，Tin）。在本提案中，我们将重点介绍两个竞争SystemC（转移的ARC和诱导耦合等离子体）中陶瓷纳米颗粒的合成，以允许对最有前途的技术进行评估。具体而言，我们将研究用二氧化硅稳定的稳定纳米化钛的合成。面临的挑战是在相对较高的温度系统中应用该材料的高光催化活性。与以前的工作一样，主要重点是反应堆设计和扩展。工业生产需要数百kW到MW的能力，而大多数实验性工作一直处于低于50 kW的量表。我们将基于过去的建模和实验性工作。
