Oxidation future research issues

In the review by Armor [1] a variety of pollutants are discussed with a focus on commercially applied processes using catalysis as a solution. Issues such as the removal of NO.v, SO.v, chlorofluorohydrocarbons (CFC), VOC, carbon monoxide, auto exhaust emission, ozone, nitrous oxide, byproducts from chemicals production, odor control, and toxic gas removal are discussed. In another review Armor [2] discusses specific topics such as monolith technology, new catalytic materials, and specific processes. Additionally, key suggestions for future research effort are given. 

The potential improvements that ionic liquids may impart to conducting polymers have been widely discussed - increased doping levels, smoother films, increased conductivity, decreased over-oxidation and improved electrochemical stability and so on. However, the research to date in this area has only just begun to investigate these hypotheses and demonstrate any material advantages in the use of ionic liquids future directions in this area must focus on some of these issues in addition to simply demonstrating the use of new ionic liquids for conducting polymer synthesis. 

Several contributions and review papers have been published on the SCR processes on metal oxides however, there are still several points that deserve to be commented upon. In this chapter, we will first discuss some general aspects of SCR with special focus on some issues and questions that should be clarified regarding future prospects and new directions of research in this field, which is centred on the use of metal oxide catalysts. Then, a more detailed discussion regarding the type of catalysts and reaction mechanism will be made for the SCR-NH3 and the SCR-HC processes.
