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，完全符合魁北克在丰富的水力发电方面令人羡慕的地位。热等离子体是生产纳米颗粒（金属，陶瓷和金属间化合物）的一种非常有效的方法，我们已经证明了它们在几个系统（Ni，Cu，Al，SiO2，TiN）中的应用。在本提案中，我们将集中在两个竞争的systemc（转移电弧和感应耦合等离子体）的陶瓷纳米粒子的合成，以允许评估最有前途的技术。具体来说，我们将研究稳定的纳米二氧化钛稳定的二氧化硅的合成。挑战在于保持这种材料的高光催化活性，同时将其应用于相对高温的系统中。与我们以前的工作一样，主要重点是反应堆设计和放大。工业生产需要数百千瓦至兆瓦的功率，而大多数实验工作都在50千瓦以下。我们将建立在过去的建模和实验工作。
