RuO₂/TiO₂催化剂在Deaon反应中的研究现状

Research Status of RuO₂/TiO₂ Catalyst in Deaon Reaction

Cl2是一种重要的化工产品和原料,其生产过程中产生了大量副产物氯化氢,造成氯资源的浪费。Deacon工艺是解决大量副产物HCl的有效方法,是氯资源“高效–清洁–循环”的重要途径之一。RuO2/TiO2催化剂具有优异的反应性能,是研究者研究的热点之一,且已在工业中应用。但是RuO2/TiO2催化剂也存在成本高和高温烧结的问题,如何降低Ru的负载量、提高反应活性和反应的稳定性是未来的重要研究方向。本文主要综述用于Deacon工艺的RuO2/TiO2催化剂最新的研究进展,介绍催化剂的反应机理、目前提高催化剂活性和稳定性的研究,并对其未来的发展进行展望。

Cl2 is an important chemical product and raw material, and a large amount of by-product hydrogen chloride is produced in its production process, resulting in the waste of chlorine resources. Deacon process is an effective method to solve a large number of by-products HCl, and it is one of the important ways of “efficient-clean-recycling” chlorine resources.RuO2/TiO2 catalyst has excellent reac-tion performance, which is one of the hot spots studied by researchers and has been applied in industry. But RuO2/TiO2 catalyst also exists high cost and high temperature sintering, how to reduce the loading of Ru, improve the reaction activity and stability is an important research direction in the future. In this paper, the latest research progress of RuO2/TiO2 catalyst used in Deacon process is reviewed, the reaction mechanism of the catalyst, the research on improving the activity and stability of the catalyst are introduced, and its future development is prospected.
